100 bitcoins is enough for my retire in 20 years later . If we account bitcoin prise for today for 100 bitcoins it is not enough for to retire but 20 years later it will change and bitcoin price will be good and it will be enough for me for retire.
Even at a price of $ 600 hundred bitcoin is still not very good amount. But if you raise to 1k then it is substantial revenues. And after 20 years, the situation may change not for the better.
