Modular chains sound pretty tough, but for a typical end-user like me, it boils down to two things: first, transaction fees and confirmation experiences feel more like "hailing a cab" — the main chain is like a highway, and rollups are like various side roads; as long as there's no traffic jam, it's fine; second, using it is more fragmented — assets move back and forth across different layers, like transferring subway lines — more routes but also easier to miss your stop (I'm still a bit wary of cross-chain/bridges). Recently, people have been using ETF capital flows and U.S. stock market risk appetite to explain price movements, which I think is more like a "weather forecast" — something to reference but not to rely on as navigation. Anyway, I always lag a bit behind, so I watch where the on-chain money is flowing first before deciding whether to get on board.
