In what one commentator could describe only as “[expletive] crazy”, Bitcoiners helped CoinWallet test the bitcoin network, and although there are still 84,000 transactions awaiting confirmation at the time of publishing, the network seems to be in good shape.
The U.K.-based exchange saved itself a lot of work by simply counting on human nature to respond in a predictable fashion and go after the free bitcoin.
They were very sly in getting the people to do their work for them.
See the unconfirmed transactions are now down to just under 30,000 so still going to be a while before all of that is cleared out.
