bitcoin still not have in our country and I think it is not available in worldwide. only few country have ATM of bitcoin. around 3k atm have worldwide according to articles.
That is no such big number.
Maybe I'm wrong but I have the feeling that Bitcoin ATMs are not so popular as they used to be and that bitcoiners don't use them so much anymore.
At least that is the case in my country. Couple years ago ATMs started to appear everywhere but now for a long time there are no new ones. I think that users have other ways to get Bitcoin or exchange it to fiat money.
