This is where we can say about transparency specially on Bustabit, but somewhat on the current existing ones are still that having no issue at all.
This is why we can say that its not the main basis on telling whether a platform or company will be credible or not.
I knew how trusted Bustabit because they are the pioneer of crash game. However, the image that you share about their stats is just is plain text without any reference for their wallet address containing funds in the blockchain.
I think declaring their wallet address that holds their bankroll is a must if they want to become fully transparent on their holdings.
I don’t have an account on bustabit, please share if their wallet is available.
