Hello,
Is it possible and legal to open an online casino without a license?
I have heard that a license only allows to put users in confidence
What do you think about this?
This is not the kind of question which can be answered in the forum, if you are thinking on opening a casino then it is better that you take this question to your lawyers and see if in the jurisdiction in which you are located you need one.
I guess there is nothing wrong to ask from this community, specially if his plan is to build crypto related gambling platform. There are a lot of experience gamblers that can give their take on it and then see how it goes to the OP. Of course a lawyer is good to ask for advise, but at least he has some beginner knowledge and could ask the correct question based on our feedback, just saying.
And if you look at the answers, majority thinks that it is very important to have a license regardless if you are going big or just starting.
Any question can be asked in the forum but whether or not the question can be answered depends on too many factors, since the question is so specific and it depends on the jurisdiction where the OP is located, or is under consideration for the creation of such casino, and since that information was never disclosed then there is not much we can do to help him.
So I do not think we can give an accurate answer to his question or even something remotely close to it.
