The number of businesses in a city accepting cryptocurrency isn't what makes it the top 10
The number of users is, by far, more important and show the real picture of the city. If a city has 100 businesses accepting cryptocurrency but nobody is using it then it's worthless. You can have 100 businesses accepting crypto but if only 0.001% of the transactions are paid in crypto then it shows nothing (especially considering most of them are small or very small merchands)
