ripple theoretical "market cap" over a billion already

[superduh]

so i was thinking about ripples.
and if i'm correct than the current value if all ripples were in public hands places the cap for the XRP over a billion dollars
how i came up with this
100,000,000,000/10,000*1btc(market rate lets say 115USD)
i know that the number is wrong since pretty much none of the XRP have been given away yet
