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?
You misunderstand me, We all know bitcoin is getting stable each year.There is rarely major fluctuation in price. I don't want my money to sit idle. I want an increase in bitcoin and increase in fiat will follow. For eg: turning 60 BTC to 100 BTC in coming years by starting a crypto business. I know it's possible with some right knowledge and ideas. At my age(27), i think it's wise to take a risk instead of just HODLING and doing nothing. Don't you think?
You think BTC is getting stable? It had 2 huge pumps this year the first time going from 4k to 14k and the second from then it went to 9k and again to 13k and it all happened in the matter of weeks. Where do you see stable here.
You also haven't seen anything yet. Bitcoin is still in its infancy with a value comparable to a single company like Amazon or Google. The first decentralized currency in the world is something less than 1% of the world owns but more people have an Iphone or a stupid paypal account.
I appreciate you trying to get more bitcoins but if you invest in a company you're putting money at risk. You could convert your bitcoins to goods that will in time give you more bitcoins like setting up a car rental company that accepts bitcoin but by the time this gives you back your 60 Bitcoin could go up in value by 200% and double your ROI time.
