1. my account was hacked and they stolen 3 btc I sent numerous requests to get back access to my account. They changed the password and implemented 2 steps verification. Please answer my support tickets #54589, #54614, #54583, #54678, #54611
2. Why is the BTC address for deposit not changing? I have the same BTC address to deposit every time. This is not good, security issues, Please make it change every time like it used to do (generate a new one on every deposit)
