I had about 12,000 last night, but powered up some of my highest CP Pokemon today. I tend to save most of it, though. I usually don't splurge it often since it's so hard to get a hold of. I kind of wish there was an easier way to get it, or if they could increase the amount you get once you're at a certain level, but at the same time, it's not like I've been starved of it either. Shrug. I just wish I had known to save it in the beginning so I didn't power up so many things that I don't even have anymore, haha.
