it is one of their ways of earning money. if you think the amount is too much, better use a gambling site that don't charge anything when withdrawing.
This is true and this is how business works on which they do earn profit out of those fee extra aside on getting from house edge alone.If you dont like their fee structure then you could always opt out
on other casinos as well which do only deduct dynamic network fees which i could say that it is really not that a headache but only seldom players do make out some small withdrawal thats why
these fees could really make you doubt on making one but much sure you do already have the idea.Stake does have high btc withdrawal fee based on my past experience.
