First of all for a newbie, ofcourse you should have first the knowledge in the crypto world. If you are a newbie and afraid to invest a lot then you better join signature campaign. All you need to do is give your time and effort to this thing to benefit well. You can earn here by just posting or replying for the given topics. But i will tell you, you need to be patient. Patience is the key always. There is no fast money here. It takes time to earn but it is all worth it. Think of it, you don't invest any money just your time and effort. All you will do is to help others by posting answers regarding to their questions or topics. Good luck and God bless!
