The price difference of each ATM is too high. I wonder what is the difference between a $20,000 and a $1,900 bitcoin ATM. Or is it just those two ways ATM that are more expensive?
And the ROI calculator seems to be a bit flawed. As far as I have seen some ATMs have insane price spread. They make extra profits from those spread and on top of that, they add the extra fees! So, they make additional profits from the spread. Looks like bitcoin ATMs are good business currently.
Shitcoins.club ATMs are two-way. You also can't buy them, the company behind them makes them and operates them by themselves.
Weren't they all taken down by the German government for operating illegally or something?
