Could it also just be the same people “zap washing?”
Discussion
It certainly could be. The problem with all-inclusive metrics like this is that you can't account for any particular type of transaction, or how a particular type of transaction in the aggregate could impact the whole, and thus the perception based on the whole. It means metrics like this aren't actually useful even if they act as ammunition for making a particular point.
particularly true with XMR perhaps since txs are fungible and the only metric is total txs
