I think you have to do more research on what you are looking for here. I tried do some research for you, I found this thread they are discussing about bonus, maybe you can check up yourself and know if you will find a link there that will help you to get your result.
https://bitcointalk.org/index.php?topic=5381232.0That casino in the link is not very well known in the forum. So better invest in popular casinos like betfury rather than putting your funds to uncertainty. Also, casitsu is offering deposit bonus not dividends by holding their tokens. So far, betfury is the popular casino which is diligently distributing their daily dividends to their token holders. Others like LUT tokens, I don't think it is worth to hold onto.
