problem solved. instant withdrawal took 4 days, but btc arrived
Bitcoin price getting up in the last few days the same thing on its transaction fee due to higher transactions. Even the withdrawal is called "instant" if the recommended fees are high then you really need have to do is to wait. Freebitco.in won't have controls the transaction once it's broadcast except the help of the miners, like accelerating it as RBF will be highly unlikely possible on exchanges and casino too.
That made sense , and its good to hear this answer so for those who have been calling for their withdrawals being delayed might understand
the reason but since This other claimant have had His funds then Maybe OP already received His but just forgot to update his thread here so
hoping He'll come back and lock this thread as what you said it is not in control of the site but its the transaction fees going merry go round
recently.
