> In blackjack with basic strategy your expected value is, what, 49%? Assuming you number is correct, that's after just one game. So you're expected to lose 2% each game (51-49). So if you play 20 games, you lose 33.3% (1-0.98^20). And you can't win against the casino in the long run. With cryptocurrency investments you can. In fact, if you choose a random time to invest, in, say, Bitcoin, you will win most of the time.
