Most cryptocurrencies are scammy because they promise revolutionary change but often lack transparency, regulation, and real-world utility. Many projects focus on hyped-up marketing, drawing in investors with FOMO tactics, only to vanish or underdeliver. The space is rife with pump-and-dump schemes, where insiders profit at the expense of newcomers. Without proper oversight, these projects can easily manipulate the market. Always do thorough research and approach with caution, as the allure of quick riches often leads to financial ruin.
