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?

I would leave part of it still in the wallet for future purpose because of the time that it will get to fir us to start using bitcoin as the main cryptocurrency, so that I dont have to start buying cryptocurrency then at an expensive price, so if I am even still considering changing some of my bitcoin to fiat for other investment reason, I would still make sure that I have enough bitcoin, but the remaining part of It is strictly going to business.
One of my first choice of business is actually landed properties, that is more like going into real estate business, because this is one of the business that is really booming in my country, and after this, I will have one of the biggest fashions company in my country where I can even earn more bitcoin by accepting it as means of payment.
