I learnt how to trade all by myself without a mentor because in Crypto currency been updated about information is more important than technical analysis that can be render useless by unsuspecting whales.
Of course, we can make our own way to become successful but that was so easy if we have some who guide and help us especially in doing technical analysis where it needs time to develop.
The next I am going to learn is technical analysis because of the people I will start teaching soon. In Crypto don't hope on shit coin and new projects.
Well, it is not difficult for you if you already understand the market behavior. But we should have to think that there is no instant way to know learn and having more time and trading experience will give you a way to develop.
