Before signing up on any gambling platform, you're supposed to go through the TOS and check if your country is among the restricted countries and if at any point some countries were added, I want to believe rollbit also sent mails concerning the new update to their customers. So I don't know if you weren't planning on withdrawing your funds for not taking such an important update into considerations. According to the information on rollbit's website, Belgium is among the restricted countries. They'll certainly use this against you and I doubt if you'll have any luck withdrawing your winning.
But what usually happen on some user is they directly go on the casino without reading the rules since they think its not needed and they are just wasting their time for reading those long text messages and they can't earn anything. This is a huge mistake they have done and its late for them to realize that they violate something or they are been restricted to play due to regulation or restricted issue that's why they had been surprised if sudden closure of account will happen to them. This is the reason why its important to read the TOS so that they would know immediately that there's something rules that implemented so that they can stay away on the problem and decide to leave if they are been restricted or not to push anything especially if they can potentially violate their rules.
