If you've been researching crypto assets (also known as virtual currencies), you may have come across the term "airdrop."

An airdrop is a mechanism in which a crypto asset project distributes tokens to people who meet certain conditions.

In many cases, tokens are given away without any payment required, so airdrops are often introduced as a way to receive crypto assets for free.

While that may sound appealing at first glance, you may also wonder whether receiving something for free is really safe.

Airdrops are not an unusual mechanism in the crypto asset world, but getting involved without fully understanding how they work can expose you to unexpected risks.

This article explains what airdrops are in a way that's easy to understand, even for those new to crypto assets.

What Is a Crypto Airdrop?

An airdrop is a mechanism through which crypto assets (tokens) are distributed to people who meet certain conditions.

To put it more simply, an airdrop is like a crypto-asset version of a promotional giveaway.

New services or growing projects sometimes distribute tokens with goals such as "getting people to try the service first" or "raising awareness that the project exists."

What's important here, though, is that tokens are not handed out to just anyone unconditionally.

People eligible for an airdrop typically include:

People who previously held a specific crypto asset
People who have used a designated service
People who have connected their wallet to a specific platform

and others who meet some kind of qualifying condition.

Why Are Airdrops Carried Out?

Airdrops are carried out to increase the number of users.

New crypto assets typically start out with low awareness, so at first almost no one uses them.

No matter how well-designed the underlying mechanism is, if no one uses it, it's essentially the same as not existing at all.

That's why projects give tokens to "people who have already used the service" or "people who meet certain conditions," as a way to first spark interest.

In a sense, it's a form of advertising — not one where the project pays cash for ads, but one where it distributes tokens instead.

Another reason is to distribute tokens more widely.

In crypto asset projects, having a small number of people hold large quantities of tokens is generally undesirable, since it can lead to price manipulation and distrust.

By distributing small amounts to a large number of users through an airdrop, a project can more easily create the impression that "everyone is involved."

What's important to understand here is that while an airdrop is a free giveaway from the user's perspective, it's an investment from the project's perspective.

The idea is to distribute tokens in advance to people who may become users in the future.

That's precisely why:

Projects with little future potential
Airdrops carried out purely for the sake of generating buzz

can result in tokens that hold little to no value even after they're distributed.

Notable Airdrop Examples

One of the most famous examples is the "UNI airdrop" carried out by Uniswap.

In September 2020, 400 UNI tokens were distributed for free to wallets that had previously used Uniswap.

The tokens were worth roughly a few thousand dollars at the time of distribution, but the price rose significantly afterward, resulting in cases where even beginners saw gains ranging from tens of thousands to several hundred thousand yen or more (roughly a few hundred to a few thousand USD).

The airdrop of ApeCoin (APE) is another example that became a major topic of discussion.

A large volume of tokens was distributed to holders of Bored Ape Yacht Club (BAYC) NFTs, which had a significant impact on the market.

There is also a project called Auroracoin, which attempted to distribute tokens to an entire nation's population.

This was an attempt in 2014 to distribute crypto assets to the residents of Iceland, and it is often cited as a unique early example of an airdrop.

The developers used the Kennitala national identification system to give away 50% of the total issuance of Auroracoins to the population of Iceland, a process known as an airdrop, hoping to bootstrap a network effect and introduce cryptocurrency to a national audience.

As these examples show, airdrops are not simply free giveaways — in some cases they attract attention as a way of rewarding users' behavior and engagement with a network with valuable tokens.

That said, in none of these cases is there any guarantee that value will rise, and it's important to understand that outcomes vary greatly depending on market conditions and how the project itself is evaluated.

Airdrop Safety and Drawbacks

While airdrops offer benefits, they also come with drawbacks that shouldn't be ignored.

This section explains the key points to be aware of when it comes to airdrops.

Scams That Exploit the Airdrop Concept

Airdrops are one of the areas most commonly exploited in crypto asset scams.

This is because the "free to receive" image tends to come first, making it easy to attract users whose judgment has become clouded.

A typical tactic is to use urgency-inducing language such as "limited time only" or "claim now or it will expire," pressuring victims into acting on impulse without time to calmly investigate — ultimately tricking them into connecting their wallet or signing a transaction.

In addition, even legitimate airdrops sometimes come with little advance notice, which makes it difficult to tell whether an offer is genuine.

This ambiguity is part of what blurs the line between scams and legitimate airdrops.

Airdrops Can Trigger Tax Obligations

One point to be careful about with airdrops is taxation.

Under Japan's current tax rules, if you receive crypto assets through an airdrop and they are deemed to have value at that point in time, they are, in principle, subject to tax.

In most cases, this income is treated as miscellaneous income, calculated based on the market value at the moment the tokens are received.

As of July 2026, gains on crypto assets are classified as miscellaneous income and subject to aggregate taxation (progressive income tax rates plus a flat local resident tax) under current law. On July 15, 2026, an amendment to the Financial Instruments and Exchange Act (FIEA) was passed by Japan's House of Councillors, which will reclassify crypto assets as financial instruments under the FIEA. This is expected to bring in a flat 20% separate self-assessment tax rate starting from the fiscal year following the amendment's enforcement (expected around January 2028). Until then, the rules described in this article, including aggregate taxation of miscellaneous income, remain in effect.

In other words, simply receiving the tokens — even without selling them — can be enough to trigger a tax liability.

Note that losses on crypto assets, including airdropped tokens, can only be offset against other miscellaneous income; they cannot be offset against employment income or other income categories.

What makes this especially tricky is price volatility.

Even if a token was worth a reasonable amount immediately after being received but then quickly lost value, the tax calculation is still based on the price at the moment it was received.

As a result, it's possible to end up owing tax even though no actual profit was made.

You should also be careful that if you receive airdrops frequently, taxable income can accumulate before you even realize it.

There are also cases where tokens that seemed too small in value to worry about later rose in price and became a tax issue.

For this reason, when participating in airdrops, you should keep a record of:

When you received the tokens
Which tokens you received
What value they had at the time you received them

Without this information, you may run into trouble when it comes time to handle your taxes.

The Cost of Keeping Up with Information Is Surprisingly High

Another drawback of airdrops is the significant cost involved in keeping up with information.

Checking whether you're eligible to receive tokens
Checking for changes to the eligibility conditions
Keeping track of when tokens will be distributed
Deciding when to sell

and other tasks require ongoing attention.

In addition, information about airdrops is scattered across official websites, X (formerly Twitter), Discord, and overseas blogs.

Much of this information is also primarily in English, so you have to judge each time whether it's accurate and not a scam.

As a result, keeping up can consume a considerable amount of time and focus.

What makes this even more frustrating is the reality that, despite all that effort, many airdrops end up having little to no value.

Even airdrops that generated a lot of buzz have often seen their price drop sharply soon after listing, resulting in:

Value that's essentially zero once gas fees are deducted
Proceeds of only a few hundred yen even after selling

Outcomes like these are not uncommon.

On top of that, the tax issue compounds the problem.

Because the tokens had value at the time they were received, they became taxable — but by the time they're sold, the price may have already dropped.

In this scenario, you can end up owing tax even though almost nothing remains in your hands.

In other words, after spending time chasing airdrops, you could still end up at a net loss.

If you enjoy gathering information or are doing it to learn how crypto assets work, there's value in the process. But if your motivation is purely to get an easy profit, you may find, before you know it, that you've spent both time and money for little in return.

Airdrops are not necessarily beneficial for everyone.

It's important to stop and consider whether participating actually aligns with your own goals and approach.

Conclusion

Depending on the conditions, airdrops can lead to gains.

That said, once you factor in the risk of scams and phishing, visible costs such as gas fees and other charges, and the time and tax burden involved in keeping up with information, it's not necessarily a favorable deal.

Beginners in particular may end up worse off if they operate their wallet without fully understanding how airdrops work, or if they chase tokens of uncertain value.

Rather than viewing airdrops as "an easy way for anyone to profit," it's more realistic to treat them as something to selectively pursue only once you understand the risks and effort involved.

If you're interested in participating in an airdrop, it's worth asking yourself:

Why is this token being distributed?
Is it really worth receiving?
Is it worth spending my time and assets on?

Keeping these questions in mind is important.

Airdrops can be a useful entry point for getting involved with crypto assets, but there's no need to chase them at all costs.

Choosing an approach that matches your own goals and risk tolerance is, ultimately, the most important factor for maintaining a long-term relationship with crypto assets.
