Pokemon-go – In Pokemon Go, which are more rare: Stardust or Candies

When you evolve a Pokemon, its CP circle stays as full as it did before.

As a result, it really doesn't matter in which order you boost a Pokemon. However, you should keep a few points in mind:

• Powerups cost more Candies the more CP a Pokemon has (based on a Pokemon's level).
• Powerups cost more Stardust the more CP a Pokemon has (again, based on level).

Cost will increase every second powerup.

Therefore, it makes sense to power up a Pokemon until it is near the upper end of your CP ring. As the ring stays in the same place, it will give you a rather decent CP per Candy ratio.

For example, if a Pokemon's max CP was 515 and it is currently at 425, it would make sense to power it up to 500 or more. At that point, you should evolve it, provided you have the candies.

Overall, you'll still be using fewer candies because you're doing most of your evolution on the lower side of the scale, and using the Evolution mechanic to sharply spike the Pokemon's CP.

The way to maximize stardust is to gain as many trainer levels as you possible can first, and then use it on pokemon that are close to maxing out anyway.

If you use it on a low level, it'll be a waste because in a couple of levels you're just going to find pokemon more powerful than the one you upgraded. So gaining as many levels as possible is your first priority.

That logic will always hold -- it is ALWAYS better to save your stardust until you're a higher level. But at some point you'll bite the bullet and decide you want to upgrade some pokemon now and do some battling. In that case, look at the half circle above the pokemon. This is an 'Upgrade Meter', where if it's filled all the way to the right, you can't use any more stardust. Pokemon you catch might start out with any amount of that already filled up. So use your stardust on a pokemon that's already mostly done for you.

See here for an example of the pokemon screen with the upgrade bar: http://imgur.com/r/pokemongo/mYu8Njh

In that case, the pokemon is about half-way powered up. I'd hold out for one that was already about three quarters upgraded.
