Bitcoin chart is going up and down some times I am thinking maybe I should invest part of my BTC (at least the part of the profit Ive made on crypto) into something real?!
Lets say I can buy share of real estate company and get the part of profit (50-100% per Year).
Should I
Spend all my BTC on that shares?
Spend small (profit) part?
Or just do nothing and wait?

?!
Ill do appreciate for answers with any suggestions and recommendations!
My opinion is that you shouldn't put all your eggs in one basket. Centralized investment is the highest risk.
Despite the profit in bitcoin, you can as well spread your investments to other sectors like real estate and others.
This will enable you have offline investment incase the your expectation is not met in bitcoin.
