Hosts of flagship CoinDesk TV show “First Mover” discuss the basics of the Shanghai upgrade, expected to take place at 22:27 UTC (6:27 p.m. ET). Part of the conversation, as mentioned, is whether this is a moment to buy or sell the news. Later, Casa CEO Nick Neuman joins to discuss the importance of crypto self-custody. Incidentally, self-custody of ETH is at above average levels, suggesting that many holders are planning to sell their holdings for fiat on crypto exchanges.
