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!
I don't see any wrong with your idea dude. For me they are both good investment as long as you have enough capital for it.
If you think that you are doing the right things, well I guess you go with it. But my advise to you is not to invest all your Bitcoin.
Just a suggestion only, so that you can minimize your loss and risk too.
