Hi there!
We keep on investigating the way the billing-software was hacked but vulnerability still can not be identified. That's why we’ve made a decision to rewrite billing software from scratch. We must admit that a significant amount of bitcoins was stolen during this attack. Currently our main goal is to restore pool's service as soon as possible.
During the pool's history there were lots of different attacks, including loss of 1170 bitcoins (TX1, TX2, TX3, TX4). 50BTC has covered all losses. Users were never affected.
At this moment we are working around the clock to restore the database and we need your assistance, because each user's case is handled individually, so please be patient.
We are expecting that in few weeks pool will get up and running with a new billing software and security system.
All users registered before October 18th will get a special conditions for mining on 50BTC.
In this difficult time for us, we are looking forward to your support and understanding. "
