Crypto isn’t useful yet outside of crime or speculation. It’s impossible to know if it’s under or overvalued. This makes it speculation by definition. It’s also manipulated by the major holders.
I know some guys who have gotten very, very comfortable (on paper, still holding) betting early on BTC and they think they’re geniuses. I’m happy for them, but they aren’t.
I don’t think there’s anything wrong investing 5-10% of an investment portfolio in speculative stuff like crypto, TSLA, etc. But huge proportionate bets will eventually burn the bettor. The smartest investors in the world are, by and large, not investing. When something like BTC, Theranos, Magic Leap get huge techbro buy-in and the sharp money stays away, this is usually a clue.
