Learning by experience is a very effective way to learn but it is also incredibly painful, it is better to try to learn all what you can before you try to become a trader, if people did this I am sure we will not see as many traders making the same mistakes all the time, another factor against trading at this moment is that many choose to invest in altcoins because they want to multiply their bitcoin in a fast way but with altcoins in such a bad shape it is better to wait until things change.
Thats the thing about trading though, you can't really learn it from reading books (except for some TA basics), you have to learn from experience. One way to get experience without suffering losses is just trading without any money, write down every trade you would make but don't actually do them, then after a while you can see and evaluate what your result would have been. Or you can also just start with a small amount, that'll feel more realistic and you won't have to worry about losses.
And then when you feel you're experienced enough you can start trading real money
