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.
Having thought of becoming rich overnight in any business will not give them a chance to make money as nothing can do that and we know that everything will have a process that we need to pass.
When we decide to invest in something, we need to learn about that so we can know what we need to do and how we can prevent the risk.
Most traders, especially new traders dream of making money from trading but they do not know that to become a successful trader needs time and skills and that will not happen in just one night.
They need to change their mind and start learning more and more to improve their skills and knowledge because that is the only way for them to make money from crypto.
