but if you have a mentor who only teaches you because you pay for his teaching, I think it is better to just self-study, because what you will pay him is better to have him buy some of the top altcoins and then hold them while studying crypto trading, what do you think? isn't good or bad idea?
That's BS.
These mentors that would like to teach than to make money for themselves, they're only in it because they can easily make money from those newbies.
I agree to just self study but maybe some of their personal experience and teachings could be of useful for someone who aspires to become a full time trader.
Not all of them are just concerned about themselves and the intention to just milk newbies because some of them are dedicated to their role in helping newcomers.
Choosing the right mentor for us is quite difficult. That is why it is encouraged to just do it on our own. The availability of information online makes it easy for us to learn. But it is a different experience if we have a mentor who guides us, as I believe it was fast and easy for us to understand, especially on technical issues.
I won't say it is not necessary, but if we can afford to acquire a mentor, it is a good idea. Provided that it is reliable and can be trusted.
