Investing in bitcoin might not be profitable this year because it is very unstable and unpredictable,most of the big players are manipulating the market isong Bitcoin's dominance,however in my humble opinion investing in mining would cost a lot before you can start but it is indeed profitable than just holding a bitcoin,in mining you can also make money while you are asleep thats why i wanted to start mining too beside of what i am doing today which is trading + bounty hunting.
