No, it's not the profound observation that crypto-markets are modern casinos - although they are. Black-Jack can teach you a lot more than just that. You only need to pay attention, and understand how things work. If you can understand Black-Jack, you can understand crypto. If you believe Black-Jack is just a card game, you should sell all crypto you own, and close your accounts like yesterday.

To understand Black-Jack, you have to understand the card deck. If you don't know that Aces count for either 11 or 1, you miss half of the Black-Jack rules. If you cannot get the correct result in the question 'how much is 6+8?' you shouldn't even sit on a Black-Jack table. Likewise, if you do not know basic economic theory and terminology - the other day someone was complaining about being scammed, because he thought APY means daily return - you should stay out of the crypto markets. You are financially illiterate, and you most probably will lose all you gamble in crypto. Learning about theory and terms by losing your hard-earned money, does not make you the Albert Einstein of crypto. Quite the opposite.

Then, we have those players who only know the rules, but they cannot understand what those rules mean and why they exist. If you cannot comprehend that your chances to draw a card counting for 10 is exactly X%, only when no cards have been already drawn, you are toast. Same happens if you cannot understand what overbought and oversold market means. Some other guy was complaining he lost all his money by taking a short position on Ethereum.

Then we have the players that know the rules, but fail to understand when those rules apply. A Black-Jack player who believes that the rule written on the table 'The dealer must draw on or under 16 and stand on or over 17' applies to him as well, will inevitably lose his socks. Likewise, halving means that Bitcoin miners will need double processing power (and probably double electricity consumption) to mint the same amount of Bitcoins. It doesn't mean the price will double overnight because of halving.

Last, come those players who although they know the rules of the game, they get addicted or emotionally attached to the game. Although they keep losing their socks, they believe that the next hand will pay back all the money they have lost. Even if and when they get luck to just get their money and run, they believe that it's their lucky day and keep betting, until they lose again everything.

Just like in Black-Jack, there are only a few professional players in the crypto-markets. They know and understand how economy and markets work, and they know when to get in and when to get out. Casino chips are worth something only in the casino. Outside the casino they worth nothing. None of the casino earnings is real, until the player cashes out his chips.

Black-Jack professionals know one more thing. The only real winners in the casino business are the casino owners, and the loan-sharks sitting at the door. But then again, even casinos may go under. In the casino business, it's the loan-sharks that always win.
