New site is terrible. How long will I be able to use old site?
Their legacy site will probably last for a while since their new site is still in the beta phase but I have to say the new design looks refreshing.
They quitely have shady reputation and I suggest to make things clear on their side before going on them there are other reliable site which is good for now so better go with already tested rather than new with questionable reputation since instead you enjoy betting on your desired team you will end up getting head aches if you get compromised.
I doubt he'll follow your advice since most of his posts are about that sportsbook. It's only going downhill from there since they stopped taking their accusation thread seriously.
