Due to recent DDOS attack on many server pools, we decided to purchase anti-ddos protection in the datacenter. It is expensive, so we are forced to set a 1% commission for the portal. We have no other choice. We want to support YENTEN and protect our customers. We do not want our customers to lose their profits. It is better to prevent a threat than to fight it.
Additionally we open one more stratum server on port 3399 for people who have a hash rate more than 100KH/s.
