Before bitcoin there were no easy way of earning other than freelance sites. PTC/GPT sites are paying $0.001 (please note NOT in bitcoin). But with bitcoin faucets we are able to earn $0.002 at least double the money for the same efforts. For an online worker, bitcoin might have brought many changes to affect his life in positive way.
Creating many easy ways to earn money must be one of very big revolution brought by bitcoin. But, I believe we are not innovating many new methods to change our life other than signature campaigns. Bitcoin has all the potential to affect our life but only if we save it for long haul.
