I couldnt disagree a trader must have a trading system,money and a good mindset,most of the new traders are lacking with these factors thats why they couldnt achieve success.
a trading system is good because it could take away the emotional side of trading. a cool trader who is just following his trading system strictly without emotions is better and stress-free compared to a trader that have no system at all and just randomly trades at will.
We should be wise and always follow the system we are using, if the system is not working anymore then we have to improve it.
It's a long term journey, you keep improving your strategy as the trend does not always happen all the time, the market is changing so as a trader
you should know how to change for improvement.
Trading is nothing but an educated gambling nowadays in crypto markets. It's something predictable, but this is solely for professional traders and brokers. Regular people can't make that accurate predicitons with the current situations.
