On the whole the bitcoin atm into usage might have increased, but in some localities ATMs have taken back as it hasn't got increased usage and wouldn't yield an earning. The usage of bitcoin atm decreased because of the increased withdrawal fee compared to the transaction fee levied on an exchange for cashing out.
I used to work in the bitcoin ATM industry during 2017's bull run, and let me tell you people were crazy about getting their hands on some bitcoins. It was incredible, some platforms charged as high as 18% over price and would still see traffic on the machines, they weren't in for cashing out, they wanted to be a part of it, buying was what was on people's mind, I'm sure that when bull market comes, this will happen again.
And even on bull market times, with the difference that more people will want to sell rather than just buy. Remember everyone hears about bitcoin at different stages of their life, and I think bitcoin ATMs are a good way to get people used to the idea that we're here to stay. Where I live bitcoin ATMs are not really popular though, I'd like to be able to use one some day
