We have a record of sales which we can show any potential buyer. The machines sell bitcoin and litecoin. We are easy to find on google and coinradar. We currently charge 17.5 percent per transaction.
I did a quick search for that area, I found many Bitcoin ATM machines so it is difficult to charge 17.5 percent per transaction.
Are there some taxes, insurance, and other expenses?
If we ignore all of this and assume that it is zero and there are no other costs.
Suppose, for example, that we charge 5% to 10% fees that make sense.
5%: 120,000*10% - (150*2*12) = 8,400/Year.
10%: 120,000*5% - (150*2*12) = 2,400/Year.
So I need 2 to 5 Years to make profits.
15000 pounds look like an exaggerated number.

Did you ask any clients before using their data commercially?
