He's right about the halving usually being priced in early, the decline after is natural though, (bit of a sell on the news event) but not evidence that the halving is of limited impact because the price generally settles at a much higher base than say 6-12 months prior. (As would be expected.)
He didn't think Ethereum could go much below $10. Again like his halving analysis underestimating the impact of inflation, downwards in ETH's case, on price.
He thinks ETH will see a surge in June, which it might if that co-incides with major ETH news. But again it's a question of mined supply being sold into relatively thin crypto buy walls. After the halving BTC can support $10 billion for less money/average demand than ETH can support 2 billion.
Also he thinks it has established itself as the second currency but imo ETH is viewed & valued by the market as a DAC.
