"Let us manage your crypto assets on your behalf and grow them for you."
Have you ever been approached with words like these by a stranger on social media or a dating app? In April 2026, Japanese manga artist Jun Tanaka disclosed having fallen victim to an investment scam, losing 5,832,000 yen.
I was caught up in a crypto asset investment scam between February and March. The total damage was 5,832,000 yen — all of my savings, gone. I might not be able to recover from this…

No specialized knowledge required — you simply hand over your funds, and profits accumulate automatically. The trading screen shows a balance that grows day by day, and small initial withdrawals are approved without a hitch. Once trust has been established this way, the moment you add a larger sum, withdrawals suddenly become impossible. This is the typical pattern of what is known as a "crypto asset management scam" (also called an asset management proxy scam).
In recent years, the tactics have grown more sophisticated, and even people with financial knowledge reportedly find them harder to spot. However, the underlying structure of these scams tends to follow recognizable patterns, and knowing the warning signs in advance can help many people avoid becoming victims.
This article walks through why crypto asset management scams work in the first place, the checkpoints worth confirming before entrusting any funds, and where to turn if you do end up a victim.

What Is a Crypto Asset Management Scam?
A crypto asset management scam broadly refers to schemes in which a perpetrator, under the pretext that "an expert or an AI will manage your assets and grow them for you," persuades victims to hand over crypto assets (also known as virtual currencies) or funds — only to ultimately refuse withdrawals or refunds. In recent years, consultations to consumer affairs centers and the Financial Services Agency (FSA) regarding these schemes have increased, prompting public warnings (source: National Consumer Affairs Center of Japan).
What makes this tricky is that the point of entry rarely looks like an investment scam at first glance. The language used is polite, and at a glance some schemes can be hard to distinguish from legitimate investment services. Here, we look at the kinds of pitches used to draw people in, and where the legal line is drawn.
The Truth Behind "We'll Manage It and Grow It for You"
Solicitations claiming to offer asset management on your behalf tend to share several common patterns. Typical phrases include the following:
- A professional trader manages the funds for you, so no prior knowledge is needed.
- It's an automated AI trading system, so your assets grow while you do nothing.
- All you need to do is deposit funds. Leave the rest to us.
What all of these have in common is an emphasis on not having to make your own decisions and not having to put in any effort. The pitch is designed to appeal especially to those unfamiliar with investing, deliberately omitting technical explanations in favor of convenience and reassurance.
Behind such pitches lies a structural problem: the substance of the "management" is never visible. Who is trading, based on what strategy, and in which assets — information that should form the basis of any investment decision — tends to be left vague, dismissed as "too technical to explain" or "proprietary to the system."
Only the outcome — "it will grow" — is emphasized, while the process of "how it grows" is never explained. This asymmetry is a trait commonly found across pitches claiming to offer asset management on your behalf. The pitch itself is not necessarily illegal, but this lack of transparency is worth remembering as a point of judgment later on.
How It Differs From Legitimate Asset Management Services: Why FSA Registration Matters
So how is a service that "manages assets on your behalf" actually treated under Japanese law? The act of holding and managing another person's assets is not something anyone in Japan can freely do. To protect investors, laws such as the Financial Instruments and Exchange Act (FIEA) require certain registrations or licenses.
A business that raises funds from others, manages them, and distributes the results generally falls under categories such as investment management business, which requires registration with the FSA (or a Local Finance Bureau). Registered operators are obligated to follow rules such as reporting their financial condition and segregating client assets, and are subject to oversight by the relevant regulatory authority. This framework is what gives users a certain degree of protection.
By contrast, many schemes referred to as crypto asset management scams are characterized by offering to "manage your assets for you" without ever obtaining such registration. Undertaking asset management without registration can itself constitute a violation of the law.
The FSA publishes a list of registered operators as well as warnings about unregistered operators. If someone claims to be "managing assets on your behalf" but their business name doesn't appear on the list of registered operators, that alone should be reason enough to proceed with caution.
That said, the presence or absence of registration is not the only factor to judge by. Because scammers sometimes impersonate registered operators, it's important to cross-check information against the operator's official website.
Why Deposited Funds Become Impossible to Withdraw
In crypto asset management scams, things often appear to be going smoothly immediately after funds are deposited. The dashboard shows growing profits, and small withdrawals may even be approved. But the moment a victim tries to withdraw a larger sum, the story changes and the funds stop moving. This is the typical pattern.
A coworker invited me, saying, "There's a system where AI makes investment decisions in crypto assets and it's profitable — let's do it together." I was also pushed to sign a contract at a seminar. When I said I didn't have the funds, I was told, "You can borrow from a consumer loan company and pay it back quickly," and instructed to borrow from two different consumer loan companies. I borrowed 600,000 yen and handed it directly to my coworker. At first, I could see on my phone that the 600,000 yen I deposited was growing through the management program, but recently I haven't been able to log in to check. When I told my coworker I wanted to stop and asked for a refund, I was told, "We'll convert it to crypto assets and refund it," and then the replies stopped and I can no longer reach them. I had heard that you get a referral fee for bringing in others, but I never referred anyone myself. I want my money back.
Why doesn't the deposited money come back? The picture becomes clearer when you look at it from three angles: how the funds are actually being handled, what the profits shown on screen really represent, and what happens when a withdrawal is requested.
The Deposited Funds Are Never Actually Invested
In most cases, the root cause of being unable to withdraw funds is that the deposited money was never actually invested in the first place. If assets were genuinely being managed, the withdrawable amount would fluctuate with market movements — but in scam cases, it's common for the funds never to have entered any real market at all.
A structure where a portion of collected funds is redirected to pay "dividends" to later participants is known as a Ponzi scheme. As long as new deposits keep coming in, dividends continue to be paid, making the operation look as though it's succeeding — but because the source of those payouts is not investment profit but other people's principal, the scheme collapses the moment new deposits slow down.
In such structures, the deposited funds often remain in the hands of the operator or are spent on living expenses or other purposes. With no actual investment activity taking place, there may simply be no funds left to return, even when users demand them. The inability to withdraw is not a temporary glitch — in many respects, it is a structural inevitability.
The Trick Behind a Trading Screen That "Appears to Grow"
If the funds aren't actually being invested, why do the numbers on screen keep climbing steadily? In many schemes, the figures shown to users on the trading screen or app have no connection to real trades. The display is simply something the operator can freely rewrite, often set to "increase" automatically in proportion to the amount deposited. Some scams use sophisticated screens that mimic real exchanges, or convincing fake websites, making it difficult to judge authenticity by appearance alone.
This "ever-growing number" is believed to serve the purpose of reassuring users and steering them toward additional deposits. As unrealized gains swell, users feel psychologically drawn to deposit even more, becoming less likely to grow suspicious along the way. Approving small withdrawals is often itself a deliberate step to build trust and encourage larger deposits. The numbers on the screen should be understood as nothing more than a performance — one that in some cases has no underlying assets to back it up.
Secondary Damage: Being Asked for "Taxes" or "Fees" at Withdrawal Time
When a victim tries to withdraw a substantial sum, they are often asked to make an additional payment as a precondition for the withdrawal. This is the stage where the damage deepens further.
Common pretexts include "taxes," "fees," "collateral," or "a fee to unfreeze the account." Victims are told things like "you must pay the tax on your profits before you can withdraw" or "once you pay the fee, we'll transfer everything at once," prompting further transfers.
Even when profits appear to be showing in a crypto asset trading account or app, attempting to withdraw them can result in being billed under names such as "fees," "taxes," or "collateral."
Under Japan's tax system, taxes are, in principle, paid by the individual through the final tax return (kakutei shinkoku) process — there is no legitimate reason to deposit tax payments with an operating business as a precondition for a withdrawal, which makes such demands inherently unnatural. Even after paying once, victims are often asked for further payments under a different pretext, with the demands never ending. Driven by the desire to recover the funds already deposited, victims comply again and again, and the losses grow — this is the structure of secondary damage.
Once you are asked to make an additional payment as a condition for withdrawal, you should treat this as a point where scam suspicion is strongly warranted.
Common Tactics and Pitches Used in Crypto Asset Management Scams
In most cases, crypto asset management scams make initial contact through channels that don't raise immediate suspicion, gradually build trust, and then request funds using persuasive language. In other words, there are recognizable common patterns in both the point of entry and the closing pitch.
Conversely, knowing these typical patterns in advance increases the chances of recognizing a crypto asset management scam when it happens. Here, we explain where perpetrators tend to make contact and what kind of language they use to cloud judgment.
Points of Contact: Social Media, Dating Apps, Investment Groups, and Impersonation Ads
Many crypto asset management scams begin in places that seem, at first glance, unrelated to crypto assets. Common points of entry include direct messages on social media, dating apps, investment-related group chats, and impersonation ads featuring celebrities or companies.
Social media | An account that appears to be a successful investor suddenly sends a message, or leaves a friendly comment. The profile may be filled with images of a lavish lifestyle and profit screenshots, designed to make you think, "I want to learn from this person too." |
|---|---|
Dating apps | The perpetrator poses as a romantic or platonic interest, builds a relationship over time, and brings up investment once trust has formed. Because it exploits romantic feelings or a sense of closeness, this approach is known for making the target less likely to feel suspicious. |
Investment groups/communities | Victims may be drawn into an atmosphere of "only select members can join" or "a mentor is managing this specially for us," with other participants in the group reporting their profits. In reality, it has been suggested that some of these participants may be affiliated with the perpetrators. |
Impersonation ads | These ads use the names and logos of real celebrities, financial institutions, or exchanges without authorization, making it appear as though the offer is officially endorsed. Many reports describe conversations with someone posing as a representative beginning after the target is led there through such an ad. |
What these points of entry have in common is that the approach comes from the other side. The moment someone brings up asset management or a money-making opportunity unprompted, it's worth pausing to think it through.
Warning Signs Hidden in "Principal Guaranteed" or "Guaranteed to Grow"
After getting past the initial point of contact, the perpetrator uses reassuring language to extract funds. Phrases worth watching closely include "principal guaranteed," "guaranteed to grow," and "absolutely no losses" — language that claims to eliminate risk entirely.
Crypto assets are inherently subject to large price swings, and the possibility of a decline in value cannot be avoided. This means that promising guaranteed profits or guaranteed principal is fundamentally at odds with reality. Even a legitimate, FSA-registered operator cannot promise "absolute" outcomes when it comes to investing.
Warning signs also show up in how returns are presented. When offers cite unusually high figures — "X% every month" or "several times your money in a short period" — that go far beyond typical investment returns, the source of such returns is almost never explained. Since high returns naturally carry commensurate risk, any pitch describing high returns without explaining the risk deserves caution.
In addition, watch for language designed to rush a decision, such as "only now," "just for you," or "act quickly before the spots fill up." Denying someone the time to think calmly can itself be a tactic to obscure facts that are inconvenient for the other party.
What to Do If You Fall Victim to a Crypto Asset Management Scam
Whether you've just realized something is wrong or you've already deposited funds, there are still steps you can take. What matters is not to follow the other party's instructions in a panic, but to act methodically. In seeking help for this kind of damage, being able to confirm the facts — when, with whom, what kind of exchange took place, and how much was sent — makes a significant difference in how smoothly the process moves forward.
Here, we outline the steps to take once you realize you've been victimized.
Immediate Actions and How to Preserve Evidence
Once you realize you've been victimized, first preserve records of your exchanges with the other party and evidence of any transfers made. The longer you wait, the more likely the other side is to delete their accounts or website, causing available information to disappear.
The first thing to confirm is whether the transfer or payment can be stopped. If you transferred funds to a domestic bank account, contact both the receiving financial institution and the one you used as soon as possible. Depending on the circumstances, the account may become eligible for a freeze under Japan's Act on Payment of Damage Recovery Benefits from Funds in Deposit Accounts Used for Crime (commonly known as the furikome sagi kyusai ho, or wire-transfer-fraud victim relief law) — a Japanese framework under which funds remaining in an account used for fraud can be frozen and distributed to victims.
If you sent crypto assets, it's also advisable to contact the domestic exchange you used and report the situation (note that once crypto assets have been transferred, halting their movement can be difficult). Alongside this, it's recommended to preserve the following records as thoroughly as possible:
- Screenshots of exchanges with the other party (chat logs, emails, call records)
- The other party's stated name, contact information, social media account, and claimed affiliation
- The receiving bank account number or crypto wallet address, along with the date, time, and amount of the transfer
- URLs and screenshots of the advertisement, group, or website used to solicit you
- Any contract, terms of service, or trading screen screenshots you were shown
These records become the material you'll use to accurately convey the situation when consulting public agencies or professionals later on. Rather than relying on memory alone, organizing everything chronologically with dates makes consultations go more smoothly.
Public Consultation Channels
Once you've preserved your evidence, it's also important not to handle the situation alone — reach out to a public consultation channel. Each serves a different role, so use them according to your situation.
Police Consultation Hotline ("#9110") | A non-emergency line for consulting about scam damage or suspected scams. You can receive guidance on whether the case may constitute a crime and what steps to take next. If the damage is clear-cut and urgent, calling 110 (Japan's emergency police line) is also an option. |
|---|---|
Consumer Hotline ("188") | A general consultation line for disputes involving contracts or transactions. Calling this number connects you to your nearest consumer affairs center or consultation desk, where you can explain your situation to a counselor. |
FSA "Counseling Office for Financial Services Users" (Kinyu Service Riyosha Sodanshitsu) | Accepts consultations and provides information regarding financial services and operator registration. Useful as a reference point when you want to confirm whether the other party is a properly registered operator. |
Note that these are consultation channels intended for people in Japan, and they are, in principle, operated in Japanese — whether multilingual support is available should be checked with each channel. Whichever channel you use, having the records described above on hand will make it easier to convey the facts accurately to the counselor. If you're unsure where to start, calling "188" or "#9110" first and following their guidance to the next appropriate channel is also a reasonable approach.
Note that cases involving crypto assets often involve legal proceedings. For individual matters, it's also worth considering consultation with Japan Legal Support Center (Houterasu) or a lawyer.

Will the Money Come Back? The Reality of Refunds and the Risk of Recovery Scams
If you've fallen victim to a crypto asset management scam, the reality is that funds sent as crypto assets are often difficult to recover. Because crypto assets can move across borders quickly, and perpetrators often route funds through highly anonymous channels, tracing and recovering them becomes considerably harder.
Also be wary of secondary scams that claim to offer "refunds" or "recovery." It's not uncommon to be contacted shortly after the initial loss with messages like "we can get your money back" or "pay a recovery fee and we'll retrieve it for you." This is a tactic that targets people who have already been victimized once. Offering to "recover" funds while defrauding the victim of yet more money is known as a recovery scam.
It is, in some cases, not legally permitted for operators without the proper credentials to handle refund negotiations for a fee. Do not respond to any "recovery" pitch that asks for money — instead, consult a legitimate channel such as Houterasu or a lawyer regarding refunds or legal proceedings.
Frequently Asked Questions About Crypto Asset Management Scams
When faced with a pitch offering to manage your assets on your behalf, it's not uncommon to be unsure how to judge it. Below, we address some of the questions most frequently raised in consultations, useful whether you're considering depositing funds or have already done so.
Is it safe if I only entrust a small amount?
The size of the amount has no bearing on safety. Starting with a small amount is often a tactic to lower your guard, get you to "try it out," and then encourage larger deposits once it appears to be working. Being able to withdraw the first few tens of thousands of yen without issue may itself be bait designed to build trust. Rather than judging by the amount, what matters is "who you're entrusting the funds to and under what structure."
I was able to withdraw funds without any problem — can I trust it now?
Approving initial or small withdrawals to build trust before soliciting a larger deposit has been repeatedly reported as a tactic. The fact that you could withdraw once does not guarantee you'll be able to do so again in the same way. In fact, cases exist where withdrawal conditions change or additional payments are demanded right after a larger deposit — so the reasoning "I've withdrawn before, so it must be safe" should be treated with caution.
How can I check whether an operator is registered with the FSA?
The FSA's official website publishes information on registered crypto asset exchange service providers and a list of financial instruments business operators. It also publishes a list of operators suspected of conducting financial instruments business without registration, as a public warning.
If the company name the other party gives doesn't appear on the registered list, or does appear on the warning list, exercise caution. That said, since impersonation of registered company names does occur, it's also advisable to check whether the contact information matches what's listed on the operator's official website.
I was shown a performance report — does that mean it's safe?
Contracts, trading screens, and performance reports are all documents that the other party can freely create or fabricate. Even a polished document or an upward-trending chart is not, on its own, proof of asset safety or actual investment activity. Rather than judging by appearances, what matters is whether the party entrusted with the funds is a properly registered operator and whether the flow of funds can actually be verified.
Is it still dangerous even if a trusted acquaintance (or friend) introduced it?
Even the person who introduced you may be unaware they're involved in a scam, having recommended it in good faith. In particular, tactics involving investment pitches from someone you grew close to on social media or a dating app are a known method of exploiting a relationship to lower a target's guard. Rather than trusting something simply because "it came from someone I trust," it's important to examine the content of the offer on its own merits, separate from who introduced it.
If the operator is overseas, is there nothing that can be done?
When the operator is based overseas, or the only means of contact is social media, tracing funds and reaching the perpetrator does tend to be more difficult. Still, before giving up, it's important to consult the police or a consumer affairs center and preserve records of your exchanges and evidence of transfers. The prospects for recovery vary significantly depending on the individual case, so consulting a public agency or professional early is recommended.
If I hire a lawyer, can I recover the assets I deposited?
Unfortunately, there's no guarantee that hiring a lawyer will result in recovery. The outcome depends on whether the perpetrator can be identified and how far the funds can be traced. Also be aware that recovery scams exist, targeting victims with claims of "guaranteed recovery" only to defraud them of further fees. When consulting a lawyer, it's advisable to find one through a trustworthy channel, such as the Japan Federation of Bar Associations or a local bar association.
Summary
Crypto asset management scams present themselves as a seemingly generous offer to "manage your assets and grow them for you" — but behind that offer lies a structure in which the deposited funds were never actually invested in the first place. Businesses that hold and manage other people's assets are required to register with the FSA, and checking whether the other party's name appears on the list of registered operators is one useful benchmark for making a level-headed judgment.
Even if you've already deposited funds, there are still steps you can take. Start by preserving records of your exchanges with the other party and evidence of any transfers, then contact a public consultation channel such as the police consultation hotline, the consumer hotline, or the FSA's counseling office for financial service users.
Legal proceedings should also be pursued through legitimate channels such as Houterasu or a lawyer. Don't try to handle it alone — reaching out to a professional early is the best way to prevent the damage from growing further.
