If you look thoroughly, then BITCOIN is just money, but like money, can it improve the world around, and humanity as a whole !?
I don’t think “good” and “BITCOIN” are the same thing, most likely the opposite.
Because of money, a person becomes weaker, he does not need to do something, to develop, because money will do it for him.
It depends on himself
If people have completely correct knowledge of bitcoin then people make a better life.
Otherwise, People are the use bitcoin illegally then he destroyed his life.
