yes there are 3000 bitcoin ATMs worldwide, but i would argue that it depicts the growth of bitcoin. The reasoning is flawed because the number of users doing the transaction on these Bitcoin ATM's is not considered while making the argument.
I think the price of a bitcoin ATM is very different compared to the price on a website so it is not worth it to use bitcoin AtM.
If they have 3000 bitcoin atm worldwide it is good because bitcoin users and investors can easily buy and sell bitcoin.
