Yup, I remember many shitcoins scammed people but it was from a time that I wasn't really interested in cryptos at all but my friend was and told me everything that was happening. So yeah, there is that too but still.
Maybe there is no fast money for crypto investment, the price goes up and down like a currency pair, high volatility if traders buy crypto coins when the price is already high, and they might suffer losses if the price then goes down, now Bitcoin is under pressure at around $58k, still need long time to get back to $73k.
