Not the only one... They’re a lot to invest in a pseudo-asset that they absolutely don’t understand! It would be difficult for a rapper to understand what a ‘smart-contract’ is in general. On the contrary, the ‘Ethereum’ team can probably rap to promote its assets... Hahaha!
Gary Vaynerchuck is an entrepreneur not a Crypto-Economy consultant or a Smart-Contract analyst!
Normal for rappers or artists in general to follow him to inject their money into 'JPEG markets' ! Scary shit!
