I would tell you that the cryptocurrency market is not so profitable as we all think.
How can you say that thing? many people have earned much with cryptocurrency so if you haven't earned from the market then you can say that its not so profitable as everyone thinks. But as someone that has been into the market for few years, I can say that its profitable if you ever bought during the dip and you took the risk for those coins that you think is worth of buying and holding.
It is only profitable to a minority of people. How many people are still in profit and in loss? 2 person in profit and 8 in loss? Crypto is profitable in a bull market. Not in a bear market. The persons who did exit in profit near $20000 were the biggest winners.
Someone who has a large amount of money is unlikely to come out, because he has gained wealth from here then he will continue to struggle to increase his wealth. Profit is not just luck but profit is the result of patience and hard work.
