Downtime is bullish, actually.
Sui's downtime reminds me of Solana, which went down countless times in 2021-2022. Now Solana is king, so evidently downtime wasn't fatal. In fact, the many outages were arguably net positive in the long run, since they provided incredible exposure opportunities. Every Solana outage brought waves of new spectators, even becoming a meme. You can't pay for that kind of coverage. ("No such thing as bad press.")
Going through downtime is painful, but it's a growing pain that all high performance blockchains go through. Many will learn about Move, Mysteceti, and Pilotfish for the first time today. And Sui will come out stronger on the other side.
