Each person own 1 Bitcoin and hold on to it for 20+ years.
Bitcoin is the best investment of all time. Owning Bitcoin is better than owning a house.
I don't saying it won't happen in future but i don't think it will happen in 20 years. And if some hold bitcoin by selling their house.Their is risk bitcoin value can decrease to zero.But if i won a house it don't have any chance to zero.
Bitcoin will make you rich or make you bust in 50 years.
