>Tether, the 6th largest cryptocurrency has a market cap of ~$160B, seems pretty "popular" to me.

MLM creates tens of billions in revenue per year in the US alone. Cryptocurrencies aren't inherently marketing schemes but they're pretty close to it and most of the value they have on markets today is basically a case of a 'greater fool' mechanism.

Also market caps for crypto is pretty meaningless. If I mint a trillion random coins and manage to sell a bunch for a dollar I'm the richest man on earth by market cap. Market cap without considering liquidity is meaningless and most if not all of these coins will go to zero as soon as someone actually tries to sell them en masse.
