I think it is smart to invest in bitcoin casinos.But do your own research first,and chose casino that is best to put your money in...You can invest in bankroll,or in casino savings account...If you want you can gamble with your profit or save it .Either way,you will earn passive income...
Having a proper plan and investing into few options a good idea. Like buying crypto, invest in gambling websites which are known ones, staking if you think that is a good option, then fixed deposit sort on the exchanges which offers this facility. These are some of the way but again check it does carry risk as well.
