Curacao license doesnt automatically means its useless but we know that having license does really give out that good impression on most people because having license means legit but we know on how easy they could really get that license which we had seen several sites does have it turns out to be a scam.
For Roobet reputation then theres no question.There might be some past issues or complaints but doesnt mean that it hadnt been resolved.
They do make out some changes and they are really that aggressive towards giving good promotion.
Having an license is necessary obligation for the casino but some casinos have been accused of scam despite having Curacao license so we can say that license can give some sort of say a pre-requisite requirements but it never implies that they will perform right task.
But roobet has been one of the reputable and legit casino site operating from long time and have built the trust of players and almost all casinos have issues which are solved by the team and it's quite common so nothing wrong in that.
