Watch the FOMO feed for an hour and the pattern is plain: most buys land on Robinhood Chain. Fresh launches, stock-themed memes, four- and five-figure entries. FOMO's data provider lists it as the busiest chain on the app. If you want to follow those traders, you have to be on that chain when they are.
One chain also keeps the engine honest. Every copy is a USDG swap routed by Relay, on a chain where gas costs cents. There is one balance, one explorer link per receipt, and nothing to bridge mid-trade.
Solana and BNB Chain are next on the list. They'll arrive when the sell test and receipts work there as well as they do here, not before.
