1 satoshi costs 100$,, really not bad for dreaming but does not seem to be realistic at all, it is just like a dream of a kid who thinks almost everything impossible or near impossible, maybe bitcoin will reach that point some day, but we wont be alive to see that i guess.
That will only happen when there is very bad inflation of the US currency. Otherwise it will take many centruries to reach that level.
and the huge inflation is going to happen pretty soon in my opinion, i hope that the price is going to be even bigger than 50 k dollars
