Yeah if oyu just want to maximize value i would (1) wait for coins, and (2) put most of your stones into step up banners where you basically get an extra 33% stones because every third multi is free. Of course you can still get shafted even with a lot of stones on a step up, but you're giving yourself the best chances you can get, which with RNG gacha is all you can ever do really. If it were me id say save for 4 year, then save for zamasu/trunks.

Sadly, those two celebrations might be close together depending on how the timing of things goes on global since we already got the hit banner that was between the two on JP and goku might get pushed up to fill space. Either way those two are what I would prioroitize but that's only if you just want the best chances for your stones, if you really love goku black or anyone else by all means summon. You have to put the stones to the RNG gods at some point lol
