Still way to viable for me to consider it a part of my retirement investment portfolio, more power to you if you press it home and are successful but right now this method a risky.
Bitcoin is digital currencies and only work if you have a internet connection and PC.If you think government can give retirement funds then its impossible.
It is good idea bitcoin is the only source to make huge money in less time and that is the reason for my investment in bitcoin. I want to do many things from bitcoin earnings. I want to buy my own house, car and also want to start some business of my own in the future. My retired life will be easy due to bitcoin. I dont care about the price of bitcoin today because I have invested for long term.
