The only reason to transfer it is if you ' re pretty sure you ' ll get another best moveset with better IVs in the next month or two . I ' ve been playing for almost 5 months now and only have one Fire FangFire Blast . I think transferring a 67 % IV best moveset mon is worshipping IV ' s to the point of shooting yourself in the foot . 67 % is a nonissue until you ' re like level 35 or something . If it was 10 % and every single power up was a ton of dust and candy , sure fine . 67 % isn ' t bad at all . I routinely evolve 50 % IV mon if they ' re level 2830 and have high CP . The epic amount of dust it saves from not powering up a 90 % level 20 egg hatch is crazy and actually getting use and earning coins from mon for months instead of waiting for more perfection is the definition of opportunity cost . I think my 40 % Slowbro from when the IV bug made high IVs in the wild impossible made me as much or more money in gyms than any other of my mon . There are only a few mon I ' m taking to level 40 , everything else can deal with a balance of being effcient to get to level 3335 .
