hi!I'm a beginner of the bitcoin world , i started to "use" coinbase just few weeks ago and still i've doubts about how to use it! i registered , deposited cash ecc... but i don't know how to use it properly to make some money or to trade!what i do is simply check on my app and see if the deposit has become a little bigger or a little smaller , i tried some  guide but i can't find anything useful ....can someone give me any suggestion ?thanks
