Good question ! If you compare those stats with some previous (https://steemit.com/cryptocurrencies/@radiuminhuman/global-cryptocurrencies-market-cap-is-higher-than-australia-narrow-money), you will see that in around one month the exchange volume rise from 0.14% to near 1% (of wordwide daily FX 24h) and from 0.35% to near 1% (of wordwide stock exchange market cap). In my opinion this accelerating movement may answer by itself to your question. In order to be sure, we may wait that global cryptocurrencies market cap will take the first place (stock of narrow money) which is $7T (China), still require a x10 multiplicator !!! So we may wait a little bit ;-) You may see the evolution if you look https://steemit.com/@radiuminhuman. Regards
