Common risks of cryptocurrency airdrops include:

Fraud Risk: Some airdrops are scams where fraudsters use fake airdrop activities, impersonation, and other means to lure users with free tokens, create phishing websites mimicking legitimate projects, or impersonate well-known platforms and influencers to deceive users into revealing personal information, wallet addresses, and private keys, leading to asset loss.

Value Fluctuation Risk: The value of airdrop tokens is highly unstable and can quickly depreciate or even drop to zero due to market fluctuations or poor project development. Most airdrop coins have low initial value and poor liquidity, making them difficult to trade or exchange.

Security Risk: Connecting a digital wallet to participate in an airdrop may expose the wallet to security risks. If the wallet used has vulnerabilities or is attacked, the tokens can be easily stolen.

Information Disclosure Risk: Participating in airdrops often requires providing personal information, such as email addresses and wallet addresses, which may be sold or used for marketing, causing harassment or other potential risks to users.

Tax Risk: Different countries and regions have different tax treatments for cryptocurrencies, and airdrop income may be taxable. Not understanding the relevant regulations may lead to tax risks.

Market Order Risk: Some project teams manipulate market prices through large-scale airdrops, causing market chaos and unfair competition, affecting normal market order and increasing the difficulty for investors to make judgments.

Trading Restriction Risk: Airdrop tokens may have trading restrictions, such as being unable to sell or transfer immediately, affecting liquidity and the implementation of investment strategies.

Time Cost Risk: Participating in airdrops requires spending time and effort, such as completing tasks and tracking token status. If significant time is invested with poor returns, it means that the input-output ratio is disproportionate.
