In trading you always have to consider a lot about what we have, the concept of luck, and another part of the strategy, although many traders do not see it, I know that some are looking for the way to do things well, either with strategy or without strategy, but in itself casino games like slots, and roulette and others will always be based on luck, for me experience has a lot to do with when we have to bet, if we bet well it is because it goes according to the strategy and that is where the player's expertise is seen.
