Trade too much
The trading volume is too large
Know too many methods
1. it depend on situation , sometimes, market movements can change suddenly. u know like some whales make a pump scenario to coins wich low volume, and posiblity we can take some profit from that if we can follow the whale's movements.
2. well, this might have a point
3. totaly agree about this one, sometimes, when u lose , u will think using another method , but with market conditions that are still the same , it doesn't help much.because basically you have used the wrong method when you first take action trading.it actually makes you seem inconsistent.
I also think that whether to trade or not highly depends on the situation. Not only this, if someone has good day trading skills and can make even little profits on daily basis he should go for it. During the peaks of dumps and pumps, trading volume should always be as large as possible. For the last one, I think it would be enough to say that the more you know, the better you will survive.
