Who funded the buyers (not built yet)

We are deciding whether to add this. For this coin's first buyers and top holders: which wallet funded each one, which of them share a funder, and how those wallets and their funders did in earlier pump.fun launches (how many coins they were early in, and how those coins went). It is not built. If you would use it, press the button: it counts one vote and nothing else (no sign-up, no email).
