2- Do you feel safe giving out your KYC to online crypto-casinos?
My opinion: After the documents are sent, they go through a number of people and online casinos keep changing their staff from time to time and in some case, if a staff member knows my address and in case I am a high-roller I would be in some serious trouble because the staff member can track me and even blackmail me to some extent. I am ok with giving my identity to known sites like bet365 or williamhill but I am still not comfortable verifying myself at a lesser-known crypto casino.
Of course, KYC on gambling is something that you don't like but if that's the only way to do it to verify that you really won that amount then you have no choice but to proceed, so only play on a reputable gambling site with a license where they are accountable to everything that they are going to do wrong, you can also report them if you think that there is a breach of data privacy.
I think we can choose the gambling site where we want to play gambling. If we don't like to play gambling on the site that applies KYC, we can search for the other sites, and I am sure that will not be difficult for us, especially when we use crypto to gamble. Besides that, we already have so many reputations gambling site which does not ask about KYC to their members. If they win, it will be their member's money, and the casino will let them withdraw if they don't do something suspicious.
