That really sucks. Although, as only 2-3 plots belong to such mini-wallet, your “Estimated Time to Win” is like thousand years, but still possible to be lucky, though. Maybe you could just start consolidating those mini-pools, and dump those extra wallets. Or, I assume you use just one cold wallet on all those mini-pools.
Thankfully, I don’t have those problems. All my plots are K32, though, and all are MadMax generated (on few computers). Maybe that is a K33 or latest OG “feature?”
Sometimes, I am thinking that Chia Network signed a deal with energy providers, and are creative to have us replot from time to time for no reason, where they get some kickbacks. Of course, not true, but all the pain is on our side.
