powerbet.io is a marathonbet clone with a higher (1%) margin  (markets, handicap and total lines all the same , checked tennis and basketball)

it was so easy to detect, only some russian bookmakers offers all quarter team totals so early in the day

I am also experiencing problems with PowerBet. I have had a withdrawal on hold and pending for over a week now and Support has not responded to any of my contact messages.

Peeps, can you check with them, since you have had contact with them in the past?

Thanks!

I'd be happy to send in verification. I asked them to let me know what I need to provide. Still no reply.

Has anyone been able to withdraw in the last week?

I had been able to withdraw fast and easy at first.

Now, silence. No replies. Nothing.

Not good.

But they are still up and running. They haven't closed the site and run away. But the OP on their Bitcointalk.org thread has not been posting lately and he was very responsive and seemed to be legitimately providing client services early on.

Hoping for the best, but preparing for the worst. I had a very lucky winning streak and maybe that is why I have been ignored and withdrawals held up.

If you shoot me a PM with your account number and permission to look into your account, I'll try to find out what's going on.

"D" books aren't recommended.

When lines of communication are lost, along with no pays, a book will be rated "F" since the chances of recouping losses is slim.

1xbit replies to communications. If anyone needs help, feel free to send me a PM.

Their rating will be up again soon. They were offline for quite a while which is why they were taken down. It was done as a precaution to see if any changes had occurred.
