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?

60BTC in 5 years? That's 12BTC a year! Even if we take a low price of 3000 USD which was the low for the last 3 years it's still 36k USD a year. That's some serious money. You must be working hard 24/7 or gambling, or you are a UN MP those people get paid big money for nothing

Holding BTC is already an investment. Why would you double the risk by reinvesting an investment?
Think in the terms of physical goods. You have a house that you're renting out and that gives you a good passive income with a small degree of risk but now you want to go play poker and put your house on the table. Do you need more money so much?
