Well, I ignored a few warnings in their main thread, and now i'm waiting 3 days for a payout of around .5 BTC.
Seemed too good to be true - actual pinnacle odds with no account hassle, and direct payment back to BTC address. But then grading started taking hours. He seemed responsive via pm (but red flag that my post about not being paid was deleted from their self-moderated thread).
I kept getting stalled via pm "sorry automated grading is down" etc etc. Then finally was told i would be paid manually. Bets were finally graded win after 2 days, but no payment arrived.
It seems like a 1-person shop who coded up a simple site to copy odds and accept bets. At this point 3 days later being incompetent is indistinguishable from being a scam. I know making this post now decreases whatever chances I had of getting paid, but so be it. Be careful.
I never heard this site, is it a new site? It is very dangerous to play in a new site without any reliable proofs, so you shouldn't bet there actually, you can choose some other reliable sites, but you didn't, does it have any good promo so you deposited money there?
