1.275mbtc from 1mbtc in free chips it's a very good result, because if it's the same for me, they were available on an Evolution Bombay Club Blackjack table with a minimum bet of 0.25 mbtc, that is to say a maximum of 4 hands. Personally I have been lucky too this time, since I manage to win 1.5mbtc thanks to one double down.
Yeah, 0.25 mBTC min bet limit is a bit high. Most of the blackjack game has 0.05 mBTC min bet limit at Livecasino. Anyway, you are still lucky with you free bet amount as you have won 1.5 mBTC from it. I placed 4 bets of 0.25 mBTC with the reward amount and won two bets from it. I won 1 mBTC in total from the reward balance, but I have lost it back by placing few more bets.You have logged in from a different device without having 2FA enabled. This is a standard security procedure that we have to protect user accounts.
The change of device was the only reason for rejecting his withdrawal or his IP address was changed too? How a user will receive his withdrawal if he go through this situation? Sending a withdrawal verification link to the registered email address would work as standard security too in that case.
