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.
I see the issue when you try to update balance for preview. When you select Ethereum and want to see how much equivalent XMR the page has to reload due to no Javascript and when the page reloads it automatically changes the dropdown menu to default choice Bitcoin but the calculations are correct. Visually it looks like Bitcoin is selected when you check Ethereum price but I can guarantee its ETH and not BTC. You can verify by changing between Bitcoin and Ethereum and you will get different calculations.
Many user request no Javascript for security reason and this is the only solution because client-side cannot update automatically.
A proof of balance is currently being developed thank you.
