Coinatmradar is another website that provides Bitcoin ATM locations across the globe but does not provide merchant details. I also do not think they are specifically targeting Bitcoin-based retailers as I also saw hardware wallet retailers being listed on it. This is a good initiative to help anyone who is looking for more than an ATM information.
I used to visit coinatmradar to follow updates about btc ATMs in some countries to satisfy the needs of some of my clients (solo campers) but really i can't telll how reliable it is. Like i can't tell how reliable this site is as well.
