> If it ends up replacing all money then the value of a single bitcoin will be around $200B, but I'd happily characterize that claim as speculation :)
Assuming "the total amount of money in the world is $84 trillion" http://www.businessinsider.com/bitcoin-compared-to-all-of-th...
BTC currently has a market cap of ~$94b
$84t / $94b = ~894
894 * $5625 (current BTC price) = ~$5m/BTC
Am I missing something? I may be. But from my calcs seems like your $200b estimate is off by a factor of 40,000x.
