Before 2020 most of crypto's volume wasn't stablecoin based that is changed
now a huge chunk of usage is just stablecoin transfers raw value moving around onchain.
and that is real product market fit fast, borderless, dollar denominated money.

In places with high inflation Brazil, Argentina and parts of Africa stablecoins are being used like real money
in Sub Saharan Africa, they account for 43% of crypto transaction volume.

But even with $246B+ in stablecoin market cap it is still early, that is 1% of global M2.
so in the grand scheme of global money this is tiny but it is growing fast.

and now we are seeing stablecoins used in actual commerce not just trading
#Tether recently settled an oil trade in USD.

we have basically built a better cheaper and faster way to move money globally
the problem is scaling, this is really hard
when money moves at this scale the chain can not just be secure it has to be efficient, low cost and reliable under pressure
