Play on Carbon, Winning is terrible, terrible and more terrible. Software stinks, they keep getting DDOS attacks during big tourney series', their customer service is the worst.
Carbon has it's downsides but overall the play is better, the software is way better and the customer service is pretty decent. The cashouts via bitcoin are taking about 2 to 3 days per my experience. The 5% fee is meh but worth it.
***Unless you are a beast then stay away
Don't get why more people don't play here.
