First time trading and winning is rare. People get experience by losing early in trading and that is true for every other persons. the first mistake will all trader make in start is they always get in when coin already pumped thinking it will pump more but then they get dumped on and they lose.
I think high expectations always lead to disappointment, the key is to get into trading with patience and without big expectations. All thou I lost much more then I made profit on trading, I still make trades and I`m getting into the trading more and more. Most of us here never knew about trading, only now we meet with stock markets, pumps & dumps, so its normal for us to lose money before we actually start to make something of it.
When we are agreeing like losses are also part of trading, we also must admit that disappointments also part of trading. We must make use of disappointment for improving ourselves to make good decisions in future trades. When traders are failing to make use of those lessons from disappointments, they could never find improvement in their trading.
