I'm surprised no one has mentioned this before and why Stake continues to think it's acceptable behavior.
Stake subtracted $3.09 from my withdraw
https://ibb.co/mRc56hyCost of the transaction on the blockchain was only $1.69
https://ibb.co/4m3gg6LSo my question remains what did Stake do with the remaining $1.40

It is a big amount to go missing especially when some Sportsbooks don't charge anything.
It is how they run their business and how they continue to provide their services to other gamblers as well.
If you're so concern about the fee you should have think about it or read their TOS or any information regarding their site before using their service.
It isn't small amount for others but it isn't also their problem because they didn't force you to use their service on the first place it was your choice.
