Ponzi's rely on deception, but crypto projects are the complete opposite- they are entirely public. Literally every transaction is public. So the entire premise/title of this article is nonsense.

Also the shade thrown at Cardano is ridiculous. They write "Their focus on convincing YouTube influencers to promote Cardano.." But the truth is the opposite. Cardano relies on thousands of validators to secure the network, who in turn are incentivized to market themselves. So it's not that YouTube influencers were convinced to do anything- it's highly technical people that were convinced to market the network. Big difference, and actually quite smart.
