That is possible theoretically but when practical case is concerned I dont think its going to come in reality anytime in near future. It would take almost everyone or say at least majority of earths population to actively use bitcoins in daily life to have sustainable price levels but if everyone is just acquiring it instead of spending, I dont think its a good idea as far as overall bitcoin technology is concerned. I would donate my 20% of bitcoin balance to you if price hits $1 Million per bitcoin.
