I am wondering that, what kind of bussiness is this? Because i have been hearing it since last year and have not got the complete information about it , that how does it works ? How poeple can be paid by such online or digital currency.. Who are the investers and why would they invest in it just because they can invest in their money in other businesses like hotels, gyms, real estate and many more. If someone invest in it then what is the procedure and through which hurdles one will have to go through?
