I do not think that this option would be good, at least for me in my country, real estate is very expensive and it needs thousands of dollars to be able to invest in this type, I mean that the barriers to entry are very high while investing in bitcoin and cryptocurrencies is much cheaper as you can start with small amounts that can be It can reach up to 1000$, so for me investing in cryptocurrencies is much better because it needs small capital and large profit returns compared to the capital.
Of course, the investments you talked about might be very profitable, but they are not successful for anyone and they cannot work in all countries.
OP is talking about having "something apart from their bag of bitcoin", it's about
diversifying. If you are an investor, it's always better for you to not bet on one horse only, you should diversify your investments. Also, you don't necessarily need to buy a real estate property by yourself, you can buy a REIT share for $10, and thus become an investor with little money spent.
