Please don't take this as an argument, I'm only asking out of honest curiosity; how can you be so certain? I've never used either site, so I don't know, but are you saying they're using the same software? I know there've been a lot of scam accusations against 1xBet too, but I figured that was just inherent in their line of work. After a quick search, I now see that they've been banned by many countries for various abuses, they're even banned in their home country of Russia. How does a scammer get banned in Russia? Not greasing the right palms?
I understand what you mean, they are trying so hard to hide the facts (for some unknown reason). There is much more than just using the same software. I am certain there was a thread somewhere that showed all the evidence in one place, but I cannot find it right now. I will update this post when I find it.
Upon registering on both sites, the first thing I noticed was that they both share the same user IDs. In other words, if you register on second site just a couple of seconds after the first one, you will get a UID that follows the first one. While I did not take screenshots at the time, this is very easy to verify for anyone who wants to. This undoubtedly proves that both sites are using the same database; they only differ in the front end skin.
In addition, as logfiles mentioned, there is
evidence that both sites use the same wallets for their deposits, and quite coincidentally, some of the wallets are titled "x1bit" and "x1bitpaygate".
