Cryptocurrencies have taken the world by storm, but let's face it: many of them are scammy. Here's why: the lack of regulation makes it a breeding ground for fraudsters. Pump-and-dump schemes are rampant, where prices are artificially inflated before being dumped, leaving investors in the dust. Many coins lack transparency, with creators often anonymous or hiding behind pseudonyms. The promise of quick riches lures people in, but remember, if it sounds too good to be true, it probably is. Always research and approach with caution; not all that glitters is gold in the crypto world.
