well instantly some bad news. i attempted another withdraw and it got instantly cancelled for "You have exceeded the maximum allowed per transaction or per time period" so maybe they have reduced once again the amount you can withdraw per month.
my old limit was 4x 50mbtc a month. i will check in with them and see what it is now
Do you already received your initial deposit? Consider yourself still lucky since casino like this with withdrawal limits usually have a low bankroll which means they can file bankruptcy whenever they want and void your pending withdrawal.
It really sucks to undergo what you are currently experiencing since after a big win your greatest enemy now is your withdrawal which you will never experience when you just play on reputable sportsbook like Stake.com.
Always read the ToS and avoid casino with withdrawal limits because it shows weakness with their bankroll.
