Hi everyone! I'm trying to research and study as much I can, but i have problems in finding good books/articles/whatever that explain the principles of economics and trading, very important if u want to learn about coins in general. I searched in the forum but i didn't find anything like that (but a lot of other useful articles)...so can you help me? I would really appreciate a "newbie tutorial for economics/trading" if it exist 
You need to study the concept and flow of economics on books first. Economy of a country always change so better to study how it works. After that, read a lot of newspapers probably on business section where you can get real updates about the growth of economy in your country. Trading is really hard. Better for you to find a menthor first, if none, try experimenting on some good coins first. Invest on something you can affors to lose. No person becomes master on first day though.
