Actually, I found what he said about Steemit to be quite positive. Andreas isn't a true Bitcoin Maximalist, just slow to come around and trust other cryptos.
It seems like just yesterday listening to him talk and someone asked him about Ethereum, he knew barely anything about it, and was very skepticle., Now isn't he writing a book about Ethereum?
Yes, he wrote one with Gavin Wood, I watch (almost) everything he's got available in YT talks on Bitcoin & blockchain talks, which I think he's dead on about - I think the limitation of speaking about an evaluation of something you don't understand is short-sighted, that's all.
