i think some of the skins have a log under the cashier menu, where you can view activity on your account and thus would see the bonus deposited

William Hill doesnt, but most all other cryptos have these "my promotion" tabs where you can check all your bonus related info and history.
First goto the cashier.
Then when in the cashier click on the "my promotions" tab at the top center.
(I believe these new "my promotion" tabs are new the crytpos)
