Hi all,
I bought some bitcoin through Coinbase.
But I havent decide if I want to trade coins at all.
The Bitcoin just sitting inside my account.
Do I earn any profits at all?
It is all about the price of BTC againist USD. If you want to make more USD, and call it profit, yes you can. There is another way of doing this is trading your BTC for alt coins and trying to get more BTC. Second option is risky and you should learn some technical analsys before doing trade.
