As for real estate, just as with BTC, you don't have to buy a whole house or whole bitcoin. You could purchase property jointly with other people or just invest in REITs.
For me, I currently need a house that I don't fully have yet because I still have to pay it off. Other real estate assets are not yet on my list of must-haves even though I admit I want them, but not right now.
I try to provide a balance in the types of investments between home, gold and Bitcoin.
Bitcoin and gold are types of investments that I try to share in different percentages. The percentage on Bitcoin is a bit bigger but not too much different from gold because gold is still very valuable for other people which I can use as collateral to get something I want, including when I want to pay off the entire mortgage fee.
Bitcoin remains an asset I probably won't touch because Bitcoin's returns are very different to gold.
