I use it.. It like it overall.. one thing to understand about those great bonuses they offer.. they'll put a rollover on your account.. You'll need to gamble up to a certain amount before you can cash out.. I don't really understand how they get the #, but its a lot like over a few thousand...just a strategy to get players to keep the money on the site and not withdrawal.
Just an FYI to know before accepting those bonuses.. Also, bitcoin is a great way around those 7.5% CC fees.
