I have been trying to withdraw my earnings from
http://www.pokercoinpool.com.
I tried to edit my account.
I kept being prompted that an email was sent which I needed to verify before changing my account details.
I never received any email.
I also sent in an email to support but have not received any updates thus far.
It has been hours and I am worried about my earnings especially with the POW phase ending really soon.

Have you checked your account details

Lots of mining accounts get hacked because they are not secured
properly and after hacking hackers immediately change wallet-address and email-address.
