Everyone could get 1 million dollars loan from bank and purchase bitcoin and then they can get a guaranteed income during rest of their life. Unlike IT and housing, the spending on bitcoin is an investment like pension fond, but the return is much higher than pension fond
Since there will not be excessive supply like IT and housing, the bubble won't burst, it will just grow and grow and grow
I am pretty sure there is a hole in that theory, but I am sure someone else can explain it better than I can.
The error in this theory is the word "everyone". If it works at all, it can only work for some early adopters. Getting a 1 million dollar loan from a bank is also not easy unless you already are welthy.
