Try out the blackjack on
www.Stake.com and let me know what you think. We use 0.4% house edge rules which is the lowest I've seen.
It's not the lowest.
https://www.bitcoinblackjack.com is offering blackjack with only 0.36% house edge
You should recommend they fix their fairness so you don't have to change your client seed every hand for peace of mind. What's silly is when I play on that site and set my own client seed, they will override it every next hand with their own. Unless you can commit to changing seed every single hand or truly trust the operator is the edge really that low?
Stake offers 0.4% with proper fairness & higher limits. If they change how their system works I'd recommend you play there over our site.
