Thank you all, guys, for your interest in our service. In different words, you ask, in fact, the same things, so I will not answer everyone personally (no offense), but on the main topics (I hope everyone will find answers to their questions)
1.
I simply want to know what can happen for a refund to take place.
Lack of xmr reserve or technical problems.
2.
Is there always available information about the current XMR reserves somewhere?
yes. bot command /rate will print rate and reserves.
(btw today we do not have large reserves. Therefore, we definitely will not be able to exchange amounts of about 50 BTC at a time. It would be correct to check the reserve before the exchange. )
3.
For now, everything looks high risk.
We will work on our reputation. Everyone started at some point.
