These idiots are harming Bitcoin at a vital stage in it's growth phase... It just eliminates all positives things that are being done to promote Bitcoin. The Halving and the upward trend that originated
from that, where halted and turned around because of this hack. If this was managed correctly and the coins stored correctly, we would not have seen this happen. In cases like this, negligence should
have criminal charges being laid against these platforms or services. If nobody is held responsible for things like this, it will just continue in the future.
First step would be to withdraw all funds and coins from that exchange. And yes, Bitcoin was finally building up something nice, and once again everything that took us years to build up gets vanished in a matter of days by amateurs taking security not serious (if it wasn't theft committed by an employee).
