That is not true. As with all operators, we have to take steps to protect ourselves from people who try and scam us.
If you are not scamming, your withdrawal will be instant.
After registration I made the bets for lower football leagues. Shuffle limited me. Than I made bets for higher leagues and see that limits drops again. Than I go to e-sport, and Shuffle suspend my withdrawals (not even your odds in line). So Shuffle was waiting for big loses. But something gone wrong and my account just become suspended. Because it's more profitable to just freeze the funds, instead of limiting as decent bookmakers do.
I have reviewed my bets several times and wondered where you could see the deception. I saw one bet where the odds had halved in a few hours. Therefore, you are making a gesture to block payments for an indefinite period and with unknown prospects.
Have a good day.
