Suppose you earned 60
BTC by working hard for 5 years and one day you decide now you don't want to work then what would you do with that amount?
How would you invest that amount? What will you do? Hold it dreaming the price will rise? Sell it and invest the fiat? or start a business? or retire? Any ideas?

60 Bitcoins are enough to start your own local cryptocurrency exchange in your country. You can start with small cryptocurrency exchange within your own locality and build a reputation and before you know it after a couple of years you'll become a popular cryptocurrency exchange.
