or you could do this:
Instead of “24h Volume: 10,000 XMR” say “24h Volume: +8% vs yesterday.”
Or it could be all-in-one.
For example: BTC + XMR + ETH + DAI = $SUM
In this way, the total volume would be transparently shown, without detailed information on which coin generated the turnover.
At some point, eXch was targeted precisely on this basis, because an identical amount of coins appeared with the one tracked by "blockchain analysts".
