It's not actually earning a living with bitcoin because my earnings from bitcoin are not sufficient to meet my daily needs but it is really a big help on my budget. Bitcoin is really helpful to lots of people.
Only the ones with great skills and knowledge or great capitals in trading or with some popular websites or gambling websites can earn a living with bitcoin but not me and you who just earn bitcoin from signature campaigns or small trades.
you dont need huge money to start off with trading because without experience you would lose a lot, i think i would just try it with smaller sums
Have a bigger capital on your side but start it with a small one for just a trial.. if you find it good then go in with bigger capital and if you feel it is not for you then just skip it...
