What trading rules do you swear by?
Proper risk control. I had been a massive idiot in the past. If a certain coin/token is going to pump based on my research, I put 30-50% of my bankroll on that coin/token like a mighty degenerate. Now, I only do a maximum of 5% when I'm really really certain, even thought I think 5% is too big of a risk.

sometimes when I get a signal for pump, I don't even bother much because, it could also be opposite. You put money in such and you cry later because of dump. Live is about risk though.
They get out of that trading pump group.

I don't risk that much as all when I do trades, around 5-7% is too big for me already and if my order falls around that category I immediately push the panic button and call it a day.
I'm no longer the gung-ho type that I used to be. Maybe I can maturity and doesn't want to gambler more because we all know that this market is very unpredictable and most of the time it doesn't go on our favour.
