Good point cause 80% of all the newly created are hype base and this is the expanse where every crypto traders need to have knowledge not only to read the chart/candle but also have the awareness of the perfect investment in the which is not hype base.
I don't trade often cause i don't like spending much time on trading but i surprised some traders usually complain they only make losses whereas in the knowledge they lack.
True, and I forgot to mention such thing as "opportunity cost" like - okay you earned your 5% in active trading by spending 12 hours/day, but you could earn 3% (for example) with some safe bonds and with 0hrs. spent of your efforts. Was it really worth that?
And yes, sometimes get overconfident just because they get lucky for a specific period of time and they think it's their skill... and when the reality shows them that they know nothing about trading, they say they just got unlucky

I Don't understand what do you mean in 1%. Many trader brake in crypto market but many Newbie join for trading. Trading is risky way but many people make huge profits.
The fact that you mention that many people leave and come-in just prove some of the points listed - that most of the people are not even able to stay for a long enough time. But those 1% are the ones who do stay in the trading for many many years.
