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?

Starting up a business will always be a good way to invest the 60BTC . You are 100% sure that your business can make you a double of the initial investment capital you used. Businesses present real assets that will bring you income for a long term if your business addresses specific problem in the ecosystem you find yourself. Starting up a business is a good retirement plan. With that, you will have a source of a specific income at any moment in time.
