If you mean in USD, it will inevitably go up - because of rampant inflation. On the other hand, I doubt you can see the same numbers in places like El Salvador, given their average income and living costs.

There's also a risk of sampling bias, as I doubt that Lightning_over_River is used as much as Visa & Mastercard at retail/brick_and_mortar stores - and the opposite, where Lightning might be used primarily online.
