Reminds me of an article I wrote on tokenizing the FX markets 19 days back.
The numbers Grok provided appears consistent with what I gathered in my personal research, truly insane values to think of.
What's even more important to note about FX becoming based on blockchain-powered markets is that it instantly makes FX more accessible, so this value is bound to be much higher because of new onboads and also because the general flaws of traditional FX is eliminated and that would encourage more active trades.
