sometimes crypto trading is fun when you get profit and can be made entertainment, but if you get a long loss this is certainly not entertainment but the risk that must be faced by each individual who trades crypto on the market.
Crypto trading can only be considered fun when you see yourself doing things right and you are sticking with a strategy. Usually, you would not expect someone who is just busy making wrong calls, trading with emotions, losing on every trade and seeing trade as a game of luck to consider it as fun because losing is never fun.
However, when you are having winning trades more than losing trades, and even in your losing trades, you know how to always manage the risks, knowing that in most ways, it is unavoidable, there is no way you will not be seeing yourself making loads of profit over time, and that is what I classify as fun.
