Quick poll question are level up rewards too moderate?

I've noticed alot of players I use to pull grind out sessions w/ sort of gave up on leveling around level 32-5, because the had enough high CP Pokemon in gyms at that point. I've never understood why Niantic was so stingy w/ the Pokecoins. If they simply rewarded trainers w/ 50 Pokecoins pre level 30 and 100 coins post level 30 the cost would be minimal. Spoofers easily cheat that amount of coins daily. W/ each level up maybe you gain access to 2-3K stardust as an incentive instead of these Nanbab berries we immediately upon receiving them. Lol just a thought on my part.
