Passive investing in misnomers are the main problem. As you are spot on: there are no coins, currencies. As my previous post mentioned, there are no/few tokenized companies trading either.

But your disdain is still too broad and blanket.

There are plenty of ways to be productively deploy resources for profit in that market. Its typically just not a directional/long-only passive approach, it is more actively creating an asset and market until you are satisfied. Just like in other markets.
