A lot of ways of earing money with bitcoin, the most popular is faucets and signature campagins. Side ways of earing money is gambling and other unrealiable stuff.
The most legit way of earning without you engaging in risk is through signature campaign, I think it is the best job for the average people here in this forum. You can earn a decent amount if you know how to roll you earnings from signature campaign and I recommend to invest it in trading.
yeah, earning through signature campaign is not a risky method to earn some money, but you may know that there is a limit of earning with signature campaign, just like with a signature campaign you can earn up to 0.035 per week or 0.05 per week according to the limits of posts per week, so if you want to earn more you should have to take risk to invest your money in other businesses also.
Only depending on signature campaign will not be sufficient, you need to diversify you earnings by working on different things like selling service or by trading.
