Gold has almost zero merchant/POS level adoption for transacting on a daily basis and yet has a market cap of over $21 trillion. Bitcoin will probably end up in a similar place.
But I believe that mass crypto adoption requires fiat currencies to get unmasked for what they are. And that isn’t here yet.. Persist even if Bitcoin hits $18000 / $1800 , it’s going to take a while but we’re going to get there.
