I did another swap on Changelly.com today. This one was nerve-wracking because the previous swaps took less than 15 minutes. After about 90 minutes, I contacted customer service via Live Chat to have them check on it using their Transaction ID. They reassured me that the type of transaction I was doing tends to take longer than most. I am very glad I got confirmation that everything would go through because it ended up taking 2 1/2 hours to complete but everything went as expected.
