Article from August, the exchanges mentioned with exploding volume are currently doing :
Koinim - 117,992 USD
BtcTurk - 4,636,351 USD
Paribu - 3,533,808 USD
Just a comparison the above volume is for all cryptos on that exchange while the volume for only the GBP<>BTC pair is 27 million, more than 3 times.
Now let's do a bit of math and those number, and see how the 15 million Turks would have gotten their coins.
If we assume an average of 20$ worth of coins, you would need 40 DAYS!!! in which each turk would only buy and god knows who would sell just to arrive at that number.
I don't know anything about the "15 million" number, I'm just saying that if it wasn't popular there its Local board wouldn't be as popular as it is.
Then why are you arguing when I say this number is pure BS?
