If everyone who had 1 Bitcoin became a millionaire then the world would have far to many millionaires and that status would not be as prestigious as today. Some people have thousands of Bitcoin so do the math, its pretty much impossible.
i think there is about 350 000 bitcoin owners in the world. if they all became milionaires/billionaires/dagobertducks they are still nothing compared to the currently at least 12 million existing millionaires.
Not all bitcoin owners have 1 BTC. For example me.
And for the price 1 Million dollars per coin, it really doesnt matter if some have thousands of Bitcoin, or many under 1 Bitcoin, there will be only 21 Million coins total
