Cryptocurrency, bitcoin including, still remain new phenomenon for humanity and no one knows how they proceed. Therefore, "do it on your own risk" is the best advice any one can get when asking about whether should he or she be involved into the business with BTC. Yeah, for many right now people BTC is like a business and they make money by speculating its price. I'm not like them. I’m mainly interested in the technicality of Bitcoin. I don't care how long this phenomenon will last.
There will certainly be many who oppose the state about bitcoin but if you like business in bitcoin then keep going because this is a phenomenon that never knows will be over for sure every year people will know how business in bitcoin will be very profitable even though a lot with full of risk.
If someone asks of course I will answer simply because bitcoin is a currency that will be used in the future and this cryptocurrency will still be used if people still need it.
