Is there information on number of users of ETH and all chains/tokens that build on it?

So, I'm curious – and genuinely open minded – how the total number of users of Ethereum PLUS those using all tokens or higher layers that depend build on it – whatever – compares to the figures I can see in the Bitcoin (BTC) environment regarding its estimated number of users and also what can be deduced about self-custodial usage from its blockchain.

I got this question because of the talk about "strategic reserves" and I'm not hearing politicians talk about an "ETH reserve" despite my impression that actual usage by actual individual people is potentially higher on the wider-utility focused ETH than on the "digital gold" BTC blockchain.

I know such numbers can only ever be approximated, but I am interested in whatever information to which the community can point me.

Thanks.
