I hear this "no real use" a lot, but I don't think it's valid. You can put 90% of your money in bitcoin and 10% in stocks. Then you have a hybrid investment where 10% of it has real use, and the other 90% is fun investment money with almost the same returns as being 100% bitcoin. Just like with gold, if Fort Knox/etc. were all sold off and used to make computer parts and jewelry, the value of gold would collapse to some fraction of what it is now.
