With what I see with the new casinos, they're wrong with how they do it. They think that as long as they have established the website, the casino, the providers are done, they're all good to go. IMHO, that's not how it goes and all they have to do is to make sure that they also have a good security that protects the operation. It's not just all about the wallets that they have, hot, cold storage wallets that they have to protect but also their main operations and users data.
That's correct and don't forget about the community which comes next after security.
The community is where they could keep it strong and if they are keeping the community healthy through bonuses and other events then I think they can keep the loyalty of them considering the user data is intact and nothing fishy will happen to it.
I mean, I have seen news where gambling services have been selling the emails of the users in the black market and I don't know if it's real or not but if it is a rumor then something like that must be happening to become an idea.
The community on the other hand can also help vouch for the reputation of the gambling site. I have seen new players that are urged to switch by means of a friend who is using another gambling site so I think it's important to spread the word.
