I suggest you should learn first before trying to make money. After gaining enough knowledge, it should be easier for you to earn money
There are different ways, infact lots of ways we can make money through bitcoin. I dont know why people are only running into signature campaign and are too blind to see other opportunities around. I dont even have interest in signature campaign, I work for bitcoin and I think thats the best decision I ever made.
You are not interested in signature campaigns but you are using signatures in your account, LOL.
the easiest way is a signature campaign, you only need to post a few times a day during the signature campaign project that you are promoting running and there is no risk.
