These include Georgia, Sri Lanka, Austria, Belgium, Bulgaria, Croatia, Denmark, Estonia, Finland, France, Germany, Italy, Poland, Romania, Spain, UK, USA and Panama."

"In some of them, there are prohibitions inside their own jurisdictions, so that citizens cannot engage with local operators. This group includes Greece, Hungary, Ireland, Latvia, Lithuania, Macedonia, Moldova, Monaco, Norway ,Montenegro, Portugal, San Marino, Slovenia, Sweden, Switzerland, Canada, Dominica, and Dominican Republic. However, there is nothing prohibiting them from engaging with a Curacao-based online gaming operator."
Based on it Greece, Hungary, Ireland, Latvia, Lithuania, Macedonia, Moldova, Monaco, Norway ,Montenegro, Portugal, San Marino, Slovenia, Sweden, Switzerland, Canada, Dominica, and Dominican Republic are probably good countries. On the other hand Latvia, Lithuania are restricted on vave and few more providers.
