Ive never been good at math but if there is 12,216,650 BTC currently and the market value in USD is at $10,243,599,942.00 thats a current market value of $838.49 per coin. If the Market value increased 13X to the size of Facebook just do $130,000,000,000.00 and divide by the total bitcoin in circulation it should come out to $10,641.21 which is why I said give or take...
