When I registered on 5spin, I was required a whole package of documents almost with pedigree for verification of identity and further use of the platform. I was embarrassed by this, so I deleted my account on this service. How was the verification of identity in Mongolia gambling with you?

This is a standard procedure that is primarily aimed at the security of your deposit in the future. When I registered with Melbet https://melbetmn.net/en/ , I was asked for a passport photo. I asked my friend who recommended this service if this is a normal procedure, he said not to worry, he went through this process as well. This is necessary not only to receive bonuses for registering, but also to replenish your deposit and withdraw your winnings. I was not asked for any documents other than my passport, so it was really strange in your case.
