Stake has a lot of games but I don't think their number crosses a thousand or more plus stake do also have a withdrawal fee but the fees can always be manageable if we use cheap altcoins and tokens. Another thing that stake don't have but bitstarz have is the sign up bonus or the deposit bonus.
Yes, in part it intrigues me sometimes to see casinos that are not in the forum, at first I review them because there are many casinos that are not crypto-style and that do not promote them through the forum, obviously who would tell them to put the option of crypto, for us it is always better to work with money in crypto, when it comes to fiat things can be very complicated, especially when transactions are made from other banks, the fact that they arrive, some have the options of Srill or Paypal, but I think that the main thing should be at least USDT, which is well accepted, Bitcoin or other crypto maybe not due to its high volatility and it can be understood, but in the same way those sites I don't know if they are so reliable.
maybe you can request them to review your mentioned casinos. they have their own criteria as listed also on their page. for them, those are their top 5 casinos according to their criteria. every review or ranking site has their own top list depending on their reviews and experiences. so you can't expect that they will list casinos that you think are deserving on their list.
Of course what happens is that it is very difficult that with some criteria they do not coincide with those that are in the top 10 of the best casinos, there is always a lot of discrepancy and difference between what OP shows, for me there is no point of comparison, for sure stake.co, I see it well, Playbet and betcoin, I have seen other sites that are relatively new and I have also seen new threads that put a lot of mbitcasino, it may be a strong marketing campaign for this casino and they can manage to position it As one of the best in the forum, all publicity is worth it, but to compete with the big ones, it is also necessary to have some seniority.
