Just have a comparison taking an stock that has grown high, then a real estate property in a highly valued location together with bitcoin. Look at the growth at the starting of the year to the end year. None could have reached such a growth, and this is the one that makes bitcoin to be the best.
We can do this analysis of btc versus real estate and the result will weigh heavily on the side of btc. It has had an absurd growth in recent years, as well as buying a property. But when we buy a property the financial and accurate return, the btc already has a somewhat black future and no one can predict when it will go or if it will be eternal (some other means of payment may someday take its place just like it took several means of payments)
