License is only beginning. Reputation requires more time to achieve and even good casino with good reputation can break its own reputation. We can not know when it happens but if it is an old casino with good reputation, we have something good and solid to put our belief on.
The safe approach is never put all money in one wallet, one cryptocurrency, one exchange, one casino. This approach is helpful to apply for casino too. I believe in Roobet.com casino because they are very good so far but as said, people should have their safe approaches and management for their capital.
Exactly, the license doesn't mean that you are a casino with a good reputation but it helps for the general image. I have already seem multiple scam casinos that all had a license. The saying also goes: it takes ages to build a reputation but you can ruin it in seconds... It is key to always maintain your reputation by solving all issues in a correct manner.
