that would be a smart idea, investing outside crypto market. because if worst comes to crypto, you have other assets to go to.tangible assets are great as no one can steal it from you unless someone will get your land title, which is a very rare case you will hear. also, with real estate you are looking at your investments physically, you know they won't crash or fall overnight. and besides, when it comes to real estate, they increase their value overtime.
Portfolio allocation is essential, it's not advisable to have all assets concentrated in a single market, and it's even more risky if it's cryptocurrencies. Real estate is an investment in my opinion it is really safe and the risk is very low because over time real estate will always increase in price. But the biggest obstacle of real estate is the need for large capital to invest, so it is not really suitable for many people's pockets.
In addition to real estate, we can invest in other traditional business models that are not as profitable as cryptocurrencies or real estate, but it will help us withstand inflationary times.
