i do not know if i would say crypto atms have failed when it has not properly launched off yet
Yeah, I don't think they've failed at all. If there are fewer
BTCATMs than before (which I'm not sure is true since I don't have any data on that), it's because there was a boom a few years ago when it seemed like they were popping up everywhere--and the demand for them just wasn't there.
There used to be one or two machines in my town about 5 years ago, and now there are at least eight. I don't exactly live in a major metropolitan hub like NYC, either. There's no way a system like that could sustain itself.
Also, I happen to agree with those who brought up government regulation. It's strict in the US, and I bet it's even stricter in other countries. We'll see what the situation with
BTCATMs is in another 5-10 years. In the grand scheme of things, they are pretty new and a lot of people don't know about them (or don't trust them).
Edit: BTW, I seriously doubt there are going to be many $5 wrench attacks happening at
BTCATM machines that don't seem to be very popular. Have there been a lot of reports of that happening?
