Hello.

I would advise you to read "An Altcoin Trader's Handbook", written by Nik Patel.
Subjects abording in the part two are:
.getting started
.fundamental analysis
.technical analysis
.risk management
.security.
These notions are essentials in my opinion. It is read speedily and it is very usefully.
Thank you guys for the suggestions you have given, it will be useful for me as well as other new beginners to enter the crypto world like me.
