How long do Changelly transactions take?

I'm curious to know, can you elaborate on the duration of Changelly transactions? I've heard varying estimates and am interested in understanding the typical timeline from initiating a transaction to its completion. Does the processing time differ depending on the cryptocurrency being exchanged or the amount being traded? And are there any specific factors that might influence the speed of a transaction, such as network congestion or verification processes? It would be helpful to get a clear picture of what to expect when using Changelly for my cryptocurrency exchanges.
