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.
Yes its a big help because of btc i have extra money to spend for my personal needs, though i cant go full time in btc i still have time to earn btc and im contented with just that. i also have real job and business so i have to manage my time.
Yeah, some of us here just looking for extra money to spend for something we need or for saving it. We know that some people here really get into bitcoin world and make good earning for living like they're who hired us in signature campaign. For me, it's just side job if there is nothing to do (free time).
Signature mappings pay too lite to go full time, but it's a good bonus. I would try to resist the temptation of buying stuff and I would save 100% of the BTC that I make online with signature campaigns, and try your best to reach the 21 BTC goal before its too late. Who knows if a signature campaign can make you rich in 10 years.
