I not trust this site i got refused one time my withdrawal
When you want to withdraw at Roobet Casino, you have to pay a fee of $10 to withdraw any currency. Of course, there is a mandatory $10 fee for any currency you withdraw. Although not all other casinos have such a system, the same fee is rated for each currency. If you withdraw by betting at other popular casinos, you will pay much lower fees. Roobet may be a promise of their own where they won't bring the fee below $10. They may be a more advanced casino, which is why they charge a higher withdrawal fee at their casino than any other casino.
I believe that to have more explanatory information, in this link you can get an idea of how things work when it comes to withdrawals at Roobet
Roobet does not charge any withdrawal fees. However, there are network fees for every transaction sent through the blockchain or Ethereum network. These fees are determined by the ever-changing price of cryptocurrencies as well as the high volume of transactions that may be going through the blockchain or Ethereum network at that time.
For Bitcoin the transaction fee can be found at the bottom of the withdrawal page of the Cashier window. You will also notice there is a priority option - Low will be the slowest withdrawal speed, but will also be the smallest transaction fee, Medium will be faster than Low, but slower than High, and High will be your fastest withdrawal speed, but also your highest transaction fee.

based on the photo, you could see that the normal withdrawal fee is 1$ but for those people who like everything they do to be quick, then there are options, such as medium and high priority, so in this example they gave in the photo, they used the medium priority, that's why 11$ came out, I don't know what the medium and high priority will be like now that the price of bitcoin is very high, maybe even in the low priority it won't be 1$, it will be greater than 1$. but these are questions that each casino decides what they will apply, I who use stake always see very low withdrawal rates even when the price of bitcoin goes up a lot, that's why I really like stake. In the case of Roobet users, the rates seem acceptable to me.
and if people like Roobet's promotions, bonuses, games then the value of withdrawal fees will not be a big problem for people, but it is always good that people read about the fees and when they create an account at the casino they are agreeing to this Condition, then you can't complain about the high fees, casino is not an investment, it's a gaming site, so it's assumed that whoever wins, wins a lot and won't worry about the value of these fees that Roobet implemented.
