I think this is never going to happen becuase i think that the altcoin alaways will hold a higher value you know and other peopel also think that and bitcoin
will get high but not that high.
I also do not think this is gonna happen anytime soon or even ever.. its just an amount that is way too big.
its gonna be stable in a couple year and most likely around the 1000 dollar, well that is my prediction.
You are telling the truth but somehow somewhere something may happen and the price of bitcoin and alt coin get force to reach that stage may be by a very high demand of the crypto currency. AS this may be unusual, it it also to be known that saying it will be happen cannot be 100% correct. Nothing is not possible on this earth.
