This min withdraw 25$ is for always? Or just during for this promo? If only for this promo then it’s okay. But if It's for always then I think the more less minimum withdraw the more people love it. I think 10$ min withdraw is okay and suitable for all currency.

Btw I have to say this is a nice promo you are running right after launching the project. Hopefully people will be attracted by it and you will have got a huge traffic.
