We concidered partnership with probably all sites in the market

We were sugesting, asking, and talking with them dozens (if not hundreds) of times in last 3 years and inviting to join. In best way, we were rejected, but mostly - simply ignored. Casinos owners doesn't want Dinabot, as believes, that it would leak their players away to competitors, also it creates possibility to mix funds between casinos.
Ok. With your explanation, I understand your process to build up partnership with casinos. It is always hard to begin so I wish best for the team. Perhaps when Dinabot get success, other casinos will join your network.
So, things changed, we can't add new sites even if we would want. Promotion of one casino next to another causing conflicts. In result, our decision was to separate Dinabot from CryptoGamblersPub as separate product, and leave it working in way it was doing all this time. Currently we are working on reviving CryptoGamblersPub with totally different approach.
The conflict of interest is explained clearly here and the team did a good choice. It is not easy to work with multiple casinos and satisfy all of them. If they provide similar games, slots, they will see conflict of interests. I got it.
