Not sure why anyone would pay an extra 10% when they could just mix their coins for a 1-2% fee on a more TRUSTED website/service. Not trashing, just saying. Also, it's not 10x better than tumbling because any old fool can go on Genesis mining and get some "fresh" coins themself lol
Reading is your friend. If you wanted to get fresh coins from Genesis miner you would have to buy a miner, which is a awful idea, I know from experience.
