Basically, the European licenses are preferred because they follow the highest security standards, like in Switzerland. However, this does not only include the licenses from the European Union like from the Malta Gaming Authority (MGA), the Swedish Spelinspektionen or the Danish license. The license from the UK Gambling Commission is also 100% safe, even though the UK is no longer part of the EU. However, those who want to use cryptocurrencies have to go overseas and visit casinos with a gambling license from Curaçao or from the Kahnawake Gambling Commission from Canada.
