>On any given day, as much as two-thirds of the transaction activity registered on the Bitcoin network has nothing to do with buying goods and services or trading the virtual currency. Is this two-thirds of the amount transacted? Two-thirds of total transaction count? Two-thirds of bytes written to the blockchain? I assume this doesn't involve economic activity transacted in bitcoin which isn't recorded on the blockchain; for instance payments made between users on coinbase or trades on cryptocurrency exchanges.
