Many altcoins claim to be innovative but in reality have serious fake market cap issues. Many projects use pump-and-dump schemes, with market cap data heavily inflated, making it difficult for investors to identify true value. These coins are highly volatile, with a high risk of sudden crashes, often without warning. Instead of chasing such risky assets, it is better to focus on mainstream coins like BTC and other projects with solid fundamentals. Before participating in altcoin trading, be sure to conduct risk assessments and beware of traps disguised as opportunities.
