Well, I've been at Roobet for a long time, and I can attest that the security in this casino is very good, if they ask me for one more level of KYC, I have no problem giving it, I think that with a closed eye I would give it, just like Roobet would too. for Stake.com, for bitcasino.io,. SB, among other sites, I say this because they are very reliable casinos with an impeccable reputation and it is worth recognizing when a site is really good.
Yes it all depends on our comfort level and if we are not then we should avoid it as Stake doesn't have any KYC option and players prefer there but the security at Roobet is fine but it's just that I am not comfortable with sharing too much documents with anyone and play in limits only.
That is the difference, people who do not want to do it at all could play somewhere else, but people who are fine with it, also could play somewhere else too, there is nothing stopping them. You gave Stake as example, so if you are a person who do not want to share their KYC then you will use them, but if you are fine with giving it... then you can still use Stake, I doubt anyone who feels fine about giving it, would mind not giving it neither.
So all in all, roobet is limiting themselves on people who are fine with it and also like their website all at the same time. This is still allowing them to make a good chunk of money as we have seen, just not as much as they possibly could.
