The pattern repeats, slightly smaller

A new wallet bought 53,661.25 $Jimothy for 7.616603536 SOL at block 442623313. Three chapters ago, another unknown wallet arrived with 7.33 SOL. Two chapters before that, 30 SOL. The sizes vary; the timing does not — every few blocks, a fresh address shows up with mid-single-digit SOL and nothing else to its name.
