Vertcoin divide your hashrate by 2 ore income also by 2 and you get your earnings.
Or some people will figure it out to mayby to late.
For Coinchoose to just list VTC as a regular scrypt coin with no explanation that your hash rate will be cut in half because of the adaptive n-factor is dumb. That's the kind of mistake a novice miner would make. FUCKING AMATEURS.
On the other hand, people who blindly mine whatever coin happens to be at the top of that list and then dump 'em on the exchanges deserve the rude awakening that may be coming their way shortly
