Hi iv4n - yes, the lack of welcome bonus/no deposit bonus is certainly something we have considered. Reality is, with our focus on web3 and the frictionless wallet signup, any deposit/welcome bonus would be abused immediately - this would then force us to work with wagering requirements, withdrawal restrictions, account bans or similar to manage the impact. All things which we believe do not contribute to a great experience for most players.
Abuse and cheat will cause many problems for the business because cheaters will not let the casino peaceful time if they fail with their cheats. They will try to create many invalid attacks on the casino that will be not good. People sometimes can not differentiate between valid and invalid accusations.
In another scenario, if they succeed with cheating, they will cause some harm against the casino. Again, it is not good for the business.
I support your team decision to not run bonus because of your platform infrastructure.
Instead we focus on providing the best web3 experience, along with monthly tournaments, daily reel races and free-to-enter competitions that directly reward loyal players.
