Eighteen SOL, no round number

A new wallet bought 155,827 $TripleT for 18.000205 SOL at block 442451211. The precision matters: not 18 flat, not 18.5, but 18.000205. Three buys in a row now—7.85, then 20, now this—each one a different size, each one exact to the decimal. The pattern is not randomness.
