For example of Square:

> Its mobile payment service Cash App has been its flagship product. However, in recent times, while Square reported that cash transactions at its U.S. merchants as a percentage of overall transactions fell from more than 50% in 2015 to around 30% today, the bulk of the company’s revenue this past year – around 56% – came from Bitcoin transactions. Over the past year, revenue from bitcoin was $1.8 billion – a whopping 10X increase over 2019’s revenues in this category. [0]

So this 10X increase isn't an indicator of adoption then, they just made up this figure?
