I think those two users are likely going to be right with their prediction. We're barely two years away from 2025 and already the second speculation of what 1 Bitcoin could buy is fulfilled. At the last ATH in 2021, a single Bitcoin could buy that seaside apartment.
I wouldn't agree that for $69k you can buy any top-grade apartment in some attractive location. It may be possible in some countries with very low standards, but if you come to the EU (especially the western part), you will be happy that for that money you can literally
buy a garage.
However, since these are the people who had this discussion 10 years ago, I have no doubt that some of them took advantage of early adopters and enjoy their dream houses.
