Yes you read the topic right!

The biggest lessons are learnt from failure.
Unfortunately, some people fail to learn from their failure and continue making same mistake multiple times. The biggest failure is failing to learn from your failures.
I lost some money, decided to chase the market to make it back.
Many traders are not aware of this as a mistake that hinder their success while trading. The moment you're after your loss, you're bound to make silly decisions that'll cost your trade. The rules are simple; to revenge in trading simply means you're ready to pay for the consequences. You might get a successful revenge sometimes but you're likely to be loser most of the times.
- Trading every coin instead of choosing a few that I could understand their movement
Jack of all trades, master of none. Lol trading every coins that comes your way means you have no focus towards your trading. You don't need to trade every tradable coins before you can make profits, you need just a few selections that you can be to cover and study their movements and you're good to go.
Those are the few lessons I learnt from failure, what did you learn?
But tbh, these aren't the things I expected to read here after reading your topic. I already started laughing thinking I will read more about how you flipped account from $100 to zero at a go.
