Today I saw those "coincidental transfers" again, two transactions with exactly the same amount, close in time, and the comment section started speculating about money laundering or similar. Honestly, many of these can be broken down into a path: first transferring from a CEX to a common relay address, then crossing to L2, being batch processed along the way, and finally swapping in segments on a DEX. It looks like a coincidence, but in reality, everyone is using the same pipeline.

Recently, L2s have been arguing about TPS, fees, and subsidies. I'm actually more concerned about confirmation and reorganization risks. Moving quickly but getting stuck on the bridge for those few minutes is really frustrating. Now I first consider the transaction time window, gas margin, and the final confirmation level of the bridge. It's okay to go slower; at least I have a clear understanding.
