I just want to know how did you manage yourselves to become an expert in crypto trading?
How may we know if we are now expert in trading? If you understand the risks of it and now have the ability to challenge it.
Building experience is the key since you will automatically learned those trading fundamentals while on the way. With your experienced, you will be used to do trading and therefore you can now build your own strategy to make a better winning stats.
My suggestion, understand first the aspects of BUY LOW SELL HIGH method then do trades even by small ones as a start. Once you will be used to it, you can now step on much advance level and that's it, you are now building your trading experience.
Is it hard to become an expert trader from the start?
Being an expert can't be achieved if you just started. There's a process and you need to enhanced it. Goodluck.
