Gamblers these days in the crypto gambling world prefer sites with zero fees or minimal fees along with several popular cryptocurrencies when compared to sites with few cryptocurrencies and high fees.
The ones that don't withdraw much though are fine with any fee usually as long as they don't face any issues while withdrawing based on what I observed.
Of course every gamblers wants were it will be easy for them in terms of withdrawing and depositing so that they don't have to pay any fees while doing any of this things but however would a gambler continue to move from one casino to another in search of the right website with this zero fees attached? To me is not necessarily because even if a casino is charging someone for transaction fees it will not be that much and some might not even charge up to a dollar but instead just a few cent so actually is not big for someone not to afford.
It's a matter of culture, a person who pays everything, for example their taxes, their Services on time is a person who knows what each thing means and what it's worth, if they enter a casino where the transaction fee is Low they take advantage of it, but if they have to pay for the fee they do it because it's their money and it's their way of Ensuring that their money will reach their Wallet or whatever address they have entered, it's a matter of Culture, there aren't many Casinos that have a Zero fee.
