You should state the rules to get the 10% deposit bonus. Most sites usually have a high rollover to be able to withdraw that amount.

I suggest that instead of deposit bonuses you should work and get your site design UI improved and also at the very least try and prove solvency by posting a DOGE or BTC wallet with the available bankroll funds.

This is a must for most new sites because usually the bankroll is very small with new sites and usually if someone is lucky and has a big win they can cause insolvency for the rest of the users and lead to withdraw issues.
