...As much as money lost, there are money earned as well. Maybe there are 1 million people who wagered 1 dollars each versus one guy with one million dollars and just one person won and 1 million people lost. It is not as clear as that usually, but the winner people could be less than losers, but they are still there.
Not only individual traders earn money on the cryptocurrency market, but also exchanges, regardless of whether they are centralized or decentralized. I personally think that exchanges earn much more by manipulations that lead to the elimination of margin positions.
But I think centralized exchanges earns more money compare to the decentralized exchanges because more people uses them daily although with the huge traffic that they get, this can also cause their site to malfunction sometimes so they still use some of their money for the site's maintenance. Other than exchanges we also have wallets, cryptocurrency itself, and so on. The one that develops or maintains them do earn too.

Yes, there is a major difference because one is 5 usd and the other is 100 usd, the leverage multiplier that each of them use are also not the same. One is 1x and the other is 50x. Is there anything you want to know? or you are confuse if what to choose? I believe that the higher the leverage multiplier the higher the risk, also risk depends on the funds that you're going to use.
