Bitcoin ATMs are a rip-off, but they are sorely needed. They're an important liquidity outlet and a gateway for the less technically inclined. But I would love more data on them and hope to see them expand geographically and in terms of what coins they offer. The apps that track their locations and prices are a joke, and despite what shitposters on Reddit may say, they are few and far between. The only operational one near me is far from commercial areas, serving over a million people at least.
