How many BTC will make you a fiat millionaire ($) in 5 years? Why?
As I doubt bitcoin price will go totally insane in the near future I would say you will need more than 1.500 - 2.000 BTC to reach million dollars threshold.
There is probably no way that we will see price increase after the halving so it is hard to predict bitcoin price after that.
Are you serious? 1.000 BTC makes you a millionaire already at the laughably low 1.000 USD per BTC price. People here is conditioned by the 1.000 psychological barrier because it was the last ATH. I can't wait until we crush it again and go 4.000+ and we will do it before 5 years. I love when people's conditioned expectations get destroyed, and this time being optimistic is more realistic than being conservative.
