It may be so, but personally I think it's not just for that reason but because every time we see a site we also look at what its trust may be labeled as, if it is trustworthy and the fact that it does not scam, the rest are mere personal words if taken as something neutral, for me the important thing is to see if they scam or not, because that is what matters, if you have enough confidence to put money there and be calm playing with the certainty that the funds will be safe, for that reason is that the casinos you name are that way, very trustworthy, they are old casinos, they are casinos that like many others for example bitcasino.io, duelbits, among others are very trustworthy.
