Whether or not to buy bitcoin, it has a difference between the costs and risks. I prefer mining bitcoin. It may cost more, but the risk is less. Meanwhile, if we buy bitcoin, to get big profits, we also need to have more funds, and the risk is usually bigger.
I think, it would much better and exciting to get bitcoin without investing in it and it can only happen by adopting a method known as joining a signature campaign. Mining is also a mean in which miners dont have to invest any penny for buying bitcoin but the problem is he needs to set up a mining rig for himself and it can cost him some good amount. Buying is very simple and if someone can afford this way, he can definitely do it.
