"Is buying 9 incubators worth it?"

#PokemonGO: After reading that Pokémon hatched have higher IVs than Pokémon caught, I thought it would give a legitimate reason to use real world money to buy as many incubators as can be used, in order to hatch all eggs you get asap. Is it a better strategy to grind by walking than by catching?EDIT: So I went ahead and bought 8 incubators (read the comments thankfully didn't make that mistake) and started hatching everything I had. Got rid of almost all my eggs and as of right now only have 1 2km left. I realized that every egg I've gotten after that has been 5km, I'm level 18 so idk if this affects what kind of eggs I get. But so far I've found that it has been worth it. via /r/TheSilphRoad http://ift.tt/2a4jGMY
