Well, I not good at maths I do admit.
Let's see...

I play casually on DMM for 4 months, I already full amps 4 rainbow and half amps 2 gold.
If count all gems I got... really near 2k gems all over.
I'm sitting at lvl 153 with 23m coins.
I have 6 rainbow (1 from ticket 1 from gambling gacha) and about 70 gold units.
Mostly of them already evol and bloom if they can, since all the mats is easy gain.

Full time playing on Nutaku for 4 months, can only full amps 2 rainbow.
Gems I recieved for free... maybe around 300.
I'm sitting at lvl 135 with 10m coins.
I have 16 rainbow (only 4 from real money) and around 80 gold units.
Only 12 rainbow and 20 gold are full evol, since all mats is too annoying to gain.

Truth always bash someone, I believe. The point is can we admit it or not.
ah I not leaving, stay here is fun.
Himeuta FKG forum is super chill, not like here hahaha.
