I wouldn't dismiss it as a hit piece. He's obviously spending a lot of time researching what's happening in El Salvador with the Chivo wallet.
As far as i checked/found, all the information he gave, is factually correct. But yes, he is very critical of the usage of Crypto for many use-cases, but that's no reason to dismiss his research. For me personally, i like it as an alternative view of what the crypto/defi proponents are claiming.
Eg. Mentioning that it's nuts to mine BTC while they could have used the geothermal energy to lower electricity costs in the country ( since they import 20%), makes more economic sense for it's citizens.
