KYC is not really good for some people, it may because they are underage or to avoid any requirements to be a gambler. It could be also because some of KYC proccess is not easy as it seems. Some of the proccess takes too long time, and people don't have enough patience to wait for approvement. In my opinion, KYC proccess is not that necessary for gambler because most of gambler must be feeling safer to be unknown.
kyc is good to me and I don't really know why we want to hide our identity. As a gambler it is very important we reveal our identity because it is very possible to make huge amounts of money and if it an evil person that win through anonymous the fund can be channel for evils things that will be a harm to all of us.
