Finally, a rational analysis.
Stocks then forex and now crypto have been / are promoted as some "easy money" or "make money online" schemes which can't be further from the truth. As you correctly mentioned over 80% of traders lose, so much for an easy money scheme. It's mainly those unscrupulous entities which make money when most of retail traders lose.
If you coming in crypto for becoming rich overnight then you are deemed to lose money. First of all understand that there is no shortcut of success, it comes through hard work ( your knowledge) and takes time. 80% traders lose money because of there mistakes ( lack of knowledge, not familiar with trading tools, greed etc). If you are hodler, then you can earn alot from this market.
