i think you should join a signature campaign if you have no money at all. there you will be able to grow you bitcoin easily through a quality of posting. if you have money then you should buy bitocn and wait for the next higher rate.
Yeah. Signature campaign is the best way for people who are starting their new journey in bitcoin because it can helps them a lot to earn bitcoin in a fast way. I also suggest to sell service to other members like offering your programming skills or web designing and get paid on btc.
