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. )
