I think it is a big problem right now
Maybe the best way is to buy coin since there is no safe site to go

You can mine coins. Anyway, I am agreeing with you in trading. It is very profitable if you know all concepts and tips about trading. If you trade in a wrong way or in a wrong time, you will loose some BTC. I heard that
Forex.com is giving some guides about trading. Check it out, it may help you.

Kindly,
