You lose the most when you are sure that you will win
Love the quote.
That being said, although Poker is definitely good for helping teach you how to manage your money, play by the numbers and leave out emotion, it's certainly not as effective as simply learning how to trade.
However, I do think that expert poker players would almost certainly make great traders, though Poker is a much slower game than trading the crypto markets.
It might actually be better to learn how to trade first, then move onto poker, since the game would be practically inherent at that point.
