Monero not yet has a working L2 so we have a pretty good estimate of economic use of Monero.
The transactions (40k vs 400k in BTC) in contrast to speculative coins are mostly from one none-custodial wallet to another.
The tiny number tells us, that after 15 years something turned out the wrong way. We are still early, when it comes to the use as medium of exchange.
