I have 1 BTC right now, so that would mean that I would have 100,000,000 $. Of course, this will never happen 
...
Who knows? ...
thats not possible to happen as long people use bitcoin and miners continue to mine bitcoin. But it will happen I guess next century 
and everyone who are bitcoin holder and has even 10 bitcoin will be one of richest man in this community and even whole wolrd. Well thats only my opinion no hard feelings guys.Cheers!
