Yes, right, KYC is required in most cases if a player asks for a withdrawal. 
This will be one of the disadvantages of your casino. If you are preferring to attract bitcoin gamblers, you should remove this rule. Otherwise, many bitcoin gamblers wont play on your site because most of them are against KYC.
You have a lot of games to play and lots of bonuses and promos. I'm just a bit confused with the deposit promo that you're offering. It's just confusing because your game site sounds almost the same as other sites. I think you have to work on the uniqueness of it so players would remember the game site because it's really an important thing.
Nothing is confusing if you have some experiences in gambling. Absolutely the games are the sames as other sites because they are providing the games from the game providers. Uniqueness does not guarantee that players will remember the game, it is not the most important thing as well.
