Cryptocurrencies often promise high returns with little understanding required, attracting those seeking quick wealth. The lack of regulation makes them fertile ground for scams, with projects vanishing overnight or using complex jargon to mislead. While blockchain offers potential, many coins serve as vehicles for pump-and-dump schemes or Ponzi structures. Always research thoroughly and be wary of too-good-to-be-true claims. Remember, if it looks like a scam and sounds like a scam, it probably is.
