there is a transfer fee set by stake, like before it was 7k sats per btc withdrawal. but recently, because of high btc fees, they are now charging 9583 sats per transaction. but the actual fee they will pay varies, and because of the congested network they paid as high as 35k sats based from my experience. but they will only deduct their fixed fee of 9583 sats from your balance.
so yeah, i also don't believe that they will use 2 sat/byte in their transaction. they are one of the few casinos that you won't have any prob when it comes to duration of confirmation as they are paying high fees just to go thru your tx in a short period of time. never encountered this prob in stake. i won't believe as well that such tx was coming from stake.
but if you happen to play on a casino offering dynamic fees, you can select the option from slow to fast where the tx fee varies. but for stake, they have fixed fee when it comes to btc.
During all the pump market,the exchange try to get more bitcoin from us,this was the periodic action of the Binance.Even though the head of the binance exchange was changed in the recent day,the reaction remains the same from the last two all time high in the bitcoin price.Many of us come across the various transactions fee in our old transactions,but now the transaction fee of 10-20$ for each transaction was the unexpected one in the current situation.Because if the trader sending 1-2k,the transaction fee of 20$ is not seems high.But just remember the person who spend the transaction fee of 10-20$ for the withdrawal of 60-100$ dollars.
