The graph

Every wallet that has traded the coin stands here as a column. Two wallets are joined when they trade one after the other on the same side, two buys in a row or two sells in a row. The taller a column, the more wallets it has been joined to. The rings are distance from the vault: the first ring holds wallets joined straight to it, the second ring wallets joined to those, and so on outward. Wallets that no chain of edges connects to the vault yet stand on the outer ring. The grey blocks around the edge are the groups of wallets that are joined to each other but not to the vault, one block for each group.
