"WagersWallet.com", my vote, because it's quiet general. It could be used for sports betting, dice, poker or any other games. What is your project by the way?
That is a nice choice. I personally liked dicewheel more. This domain has name of gambling games and it shows the random nature of gambling too. It is not possible for a player to predict the outcome of a spinning wheel or a dice roll. Almost all the gamblers have played dice in their lives too. Above all, I found this name easy to member. Such sort of things are attractive for customers. However, your domain indicates involvement of cryptos, so it is cool in its own way.
You really have a great understanding of what a good domain name should look like. I think any serious gambling startup who's making a decision as to what domain name to choose should take your explanation seriously. Dicewheel.com is no doubt a top notch premium domain name, in the same rank with PrimeDice.com or even better.
