Cryptocurrencies often promise financial revolution, but many are plagued by scammy practices. The absence of regulation allows for fraudulent schemes and pump-and-dump tactics, where unsuspecting investors are left with worthless tokens. Whitepapers can be misleading, promising groundbreaking tech that's never delivered. The focus on quick profits over genuine innovation attracts bad actors. While blockchain holds promise, the crypto space is ripe with projects that prioritize hype over substance, exploiting the FOMO-driven market. Always research thoroughly before investing!
