Again, Bitcoin ignorance reigns supreme. When a BTC transaction is started, the ‘buying’ party software sending out BTC is able to set an amount of ‘reward’ (usually a few fractions of BTC) for the first node that catches the new transaction and confirms it. Then it propagates to other nodes for more confirmations of transaction. But there is ‘payment’ to the network node that first confirms it.
Also, when I dealt with an exchange, they DID charge a small sum for the transaction.
So the whole ‘theory’ of that article is completely bogus… ignorance.
