Bitcoin is an investment project and that project he can succed or failed so if you don't need that money you can turn your money to bitcoin and you can earn much more the value that you put on bitcoin if his price grown up in the future
not only in bitcoin but in any business it is not a good idea to invest all your money, Although bitcoin is a good source of income but still i think we cannot predict about the future of bitcoin and that is the reason that it is not a good idea to put all your money in bitcoin. i think it will be good if we put such amount of money in bitcoin that we can afford to lose.
