Do you think there is a maximum CP on pokemon go? Otherwise

not if you grind hard enough

But what if people with main from first gens also grind as hard?

They will always be ahead

They would likely begin implementing shit like boosted candy drops for new mons for a limited time like how some other phone games give exp boosts to new characters/monsters/etc.

There's always some way to balance shit out.
