Thank you for your feedback we are taking consideration of putting a minimum withdrawal, but we may apply it in the future and set a small minimum withdrawal amount.
About the promotion I think we will consider the paid honest review feedback so we should be able to receive honest feedback on our website and which part of our service that we need to improve and maybe taking consideration of running a signature campaign in the future.
In regards with our provider. Every software provider has a wide range of customers and we can't do anything if other sports betting website can use them as well.
About the gambling license, you can find it at the bottom of our gambling site and also the bottom of our ANN thread. Our gambling license is Costa Rica, we choose Costa Rica license because by law KYC is not required and with this license, more players from different countries will be allowed to play at our gambling site since it is crypto related.
I think, people are used to seeing Curacao gaming license and they can just press the logo of the license and they will be directed to the validation page, so you can see if the license is legit or not. With Costa Rica, we can't do the same. But anyway, you will earn trust in the next days to come. As long as there is no complaint or if there's an issue, you should promptly resolved it and not delay. As a new sportsbook here, expect that you will receive criticisms but you can always be transparent here so people will start trusting your site. Also, if you want, you can also run sig campaign in the forum and you can already check the services section -
