It's because most people, especially newbies, are smart and bright during the bull run. They think profiting is easy as 1,2,3. The same goes with Future Trading, once they successfully gained some profits during the first phase of their actual run, their mindset is, it's not that hard to gain profit in crypto.
And after the series of wins, consecutive losses take place which leads to frustrations, disappointment, and regrets.
It's good for me to see newbies struggling since that will be their foundation in becoming good traders in the future.
Consecutive losses filter out those newbies that don't want to continue; this is really the testing phase in which you'll see if your strategy in putting trades and your risk management are working well since no matter how good your strategy is without a proper risk-reward ratio, you'll still end up losing everything. Experience is a good foundation; losses mold you to be a better trader and also strengthen your strategy, with which you can win more trades. Mental health is also the key in trading; if you can control it, then you are good to go.
