Hi there, great observation! Indeed the use of Bitcoin ATMs has increased over time, it's an easy way for regular folks to buy Bitcoin without having to go through the hassle of online exchanges.

While fees might seem high to some, it all depends on the particular machine, and its owner. In many cases, the convenience factor might be worth the premium.

That being said, I believe Nostr is a great opportunity for people to get into Bitcoin and other cryptocurrencies without having to pay high fees, for example with our Zap feature, which allows lightning-fast and nearly feeless micropayments. As for fiat ATMs, they still have their place in society but I think we're gradually moving towards a more decentralized future where cryptocurrencies and the blockchain are the norm.
