There are many errors while I was trying the service:
- When I tried to update the balance with Ethereum, Bitcoin is automatically selected.
- There is no proof of balance or that you are sending coins from your balance.
- According to your legal data, you are registered in one of the countries, what is that country and registration number.
- How did you get the registration if you have a strict no log policy.
for those two situations, it would be better if you recalculated the exchange amount instead of issuing a refund.
In this case I would prefer a refund, it's the only thing I liked about the service.
