I use the ATM only to withdraw my funds from Bitcoin to my plastic card. Yes, the choice of cryptocurrency exchange in this service is not that large, but it's enough for me. In the beginning, when I was just starting to buy bitcoins, I had to go through verification several times for each card. I'm not a fan of such procedures, but rules are rules. Fortunately, the verification happened almost instantly, so I didn't have to wait long. As for the exchange time, the whole process takes up to an hour. It all depends on the network load and the speed of transaction confirmations by miners. To my recollection, the maximum amount I exchanged at the ATM was 0.2 BTC. Everything went smoothly.
