so if in May Bitpay average was processing $1million a day from 30,000 merchants simple maths says that by 2016 if they reach the target of 1 million merchants or 33 times what they had then volume for bitpay alone should be in the region of $33 million a day or 1 billion + a year (minimum) so an initial $30M investment looks cheap for that volume.
http://www.coindesk.com/bitpay-now-processing-1-million-bitcoin-payments-every-day/and to extrapolate further.. if the current total average daily volume of approx $50 million a day traded moves in step ..a 33 times increase will suggest that volume in 2016 will reach $1.6 billion a day
what will that do to the price HOO HAR d HAR!
