In my opinion, it is just a matter of time because I think sooner or later most casinos will do the same but I doubt that other casinos can offer the same bonus like what offered by Stake but if other casinos also do not want to lose their loyal players then they may try similar thing but maybe less amount or maybe different offer.
We have guessed this since a few years ago and for this year Stake.com became the first to do it while other casinos may be preparing another plan
One thing I worry about in another casino is that they trap users so when request for withdrawal, the user is required through KYC this scenario often occurs to force users
Instead of thinking about bonuses but they have to think about the balance
this means we must be more selective in choosing a trusted casino.
