Signature campaigns are the best way to do; but it's not easy to find one of them now 
As quoted signature campaign were the best, because one could get a reliable earning. With other methods such as trading you could get high profit but needs investment. Only way to get your whole bitcoin in a short time is to buy.
Majority of people really selects sig campaigns because in that program you can earn free money by just posting and advertise the company/site and it really helps because it can give yoy decent salary if you are a high rank member of this furom and the other program youn earn bitccoin is by tradings and gambling but you need capital for this and its to risky and need proper research and good strategy.
the most people are selecting signature campaigns are above it all but this is also pretty logical because its a safe way of gaining and it can let you make a lot of money totally free.
It still needs some skills though if your main language is not english or you live in asian countries where every country has its own dialect. I know some people who already knew about this signature campaign in this forum but they said they can't speak english fluently and can't engage in some english discussions about bitcoin.
The reason why majority of people select signature campaign as their main source of income because it doesn't need any special skills, so if someone who has no skills like designing or programming or any other skill like that so he would surely select signature campaign where you can earn money without any hard work, all you need is a little time and some knowledge.
