Compared to the global scale, 3000 ATM is less. I want to increase it.
If you want to increase the number of available Bitcoin ATMs then buy a couple and there is your increase.
In all seriousness, you can't possibly compare traditional bank ATMs with Bitcoin ATMs. Bitcoin ATMs are a niche in every possible way, and quite expensive to use, especially in the very early stage.
Earning back the initial capital of the ATMs isn't the main problem. The main problem is that you have to earn back your license costs, which easily exceed the $100,000 mark, and then there are steep renewal costs.
That pretty much explains why most ATMs are quite expensive to use. Only with mass usage they will be able to socialize their operational costs to offer lower overall usage fees.
