From what I've come to see, such investment has lots of disadvantages and limitations due to unforseen circumstances like war and government policies that could make the cite of the buildings inhabitable thereby making the investment unprofitable and sometimes most men at the point of retirements, discovering that they can't get access to all they've invested into become traumatized in the process.
Investing into Bitcoin is good and for the time being, we can actually make a ten year speculation on the fact that it will still remain a valuable and profitable investment but the question here is;
Is it wise and realistic for someone in his early twenties to set up Bitcoin as a retirement plan such that he continues accumulating Bitcoin from this time till he gets to his retirement age?
It is clearly wise for those in their twenties to try to accumulate Bitcoin between now and retirement. But on the one hand there is also another question that arises from this, namely whether young people who are still in their twenties are able to hold Bitcoin for that long because usually young people nowadays are more easily tempted by luxury things that make them try to buy it. So they often forget that they are planning their retirement by collecting Bitcoin by continuing to hold Bitcoin until that time comes later in their life.
Apart from that, everyone should not ignore fleets such as houses and several other assets that can be useful for their lives and also for future generations through their own families. Because whatever the regulations from the government and natural disasters that can appear suddenly without us realizing it, residences such as houses and buildings that can be used as investments for the future must also be considered important.
Because if someone is afraid to make that kind of investment in their life just because of natural disasters and regulations from the government, I think Bitcoin investors will also feel something that is not much different if a natural disaster can destroy the internet in their area. Likewise with regulations from the government which you don't need to be afraid of because if you are afraid to invest because of that, it means you have to become the leader of that country or create your own country whose rules you can make yourself
