The reason I can prefer bitcoin is because there are many ways I can protect the coins in ways that no one on earth can steal my coins from me. Some people can make mistakes but if you have the right knowledge about how to protect your coins, no one will be able to hack it. And the security would be of low cost. Unlike physical assets that would be of high cost.
Even with the high cost, physical assets are still subject to destruction at the emergence of unrests of any kind, you can see over the news in northern and western Nigeria how physical assets were destroyed and looted on the very first day of protest.
Physical assets drags attention easily unlike digital assets which you can have in abundance and still keep a low profile.
Taxation is more on physical assets than digital assets.
In as much as physical assets are good, I strive for limited physical assets and more digital assets.
There are some physical assets that are worth it. No one can steal your house if you have the legal backup. Also are real estates and land. But that is if you go the right way and have the legit property papers. There are physical properties that can not be stolen.
Yes, I agree with you, Real estate is a very important aspect of investment, but you need to watch out where you make such investments and stay off troubled zones, so you don't end up losing them easily to violence, or not being profitable owing to unfavorable living and business conditions
