Yeah a lot will depend on how much variation there is. I'm hoping that there are enough territories with changes to say something convincing, but I'm not sure.

I'm also curious as to whether willingness to pay fees and willingness to zap changes when bitcoin price changes.

There's a lot of potentially interesting things to do with this data

I love this

Have you thought about looking into marginal rates of substitution between territories, once you have those posting fees? Maybe there's not enough variation, since most territories have pretty stable fees, plus entry and exit will make it complicated.
