Trading books recommendation

[arcassis]

Hi,

I've started with cryptocurrencies back in August 2017.
I admit that it was and still is very hard to make a wrong investment nowadays but the idea is to evolve.

So I've opened this thread to talk about what would it be your recommendations when it comes to books/sources about 1) trading and 2) economics in general.

PS: A book I've been recommended by a good friend of mine who's a very good trader is Trading in the zone by Mark Douglas.
