Reasons for Hoarding Coins?
Is it sensible to keep hoarding gym coins beyond 14500? Does anyone else keep a stash of coins? And if so, why?
Some background...
I hit that milestone today after spending an additional 9500 on storage, lucky eggs, and incubators along the way. With gyms I've been a little bit clever and somewhat active, but mainly just lucky, averaging 82 coins per day since starting in July.
[The luckiness of this gym situation might be expressible in numbers by looking at my total gym coins (24000) compared to total battles (1404 training + 337 attacking = 1741), which comes to 13.79 coins per battle.]
I mainly play as a diversion while walking my dog, and don't feel the need to rush anything in the game beyond having 12-15 adequate gym defenders. For example, I just got my first Dragonite this week, and might not have my first Tyranitar until a year from now... which is fine by me. My dog still walks with me in spite of my mediocre roster.
Initially I wanted coins so that I could increase storage (now maxed) and level up (currently 35), then so that I could incubate freely during events (done), and finally so that I could stash coins for future reworks and events.
I don't feel an urge to level up any faster or hatch tons of eggs - especially outside of events. Incense wouldn't add much to my dog walks, and I don't play stationary enough for lures.
I'd pay twice as much for storage beyond 1000, or for items that increased my chances of getting a legendary... but those options aren't available. So the coins keep building up, and I wonder whether I should bother to keep earning them - even when I'm lucky enough to live in an easy earning environment.

With that amount of coins and if you already have maxed out inventory and mon space then I would just buy stacks of incubators every week or two weeks, if your gyms are stable why keep saving them? You already would have that Tyranitar and a maxed out Dragonite almost for sure if you spend coins on incubators. They are just uncommon from 10k, I have hatched 6 Larvitar already. I just save 3600 for the next event and spend the rest, 3 rounds of incubators are more than enough for any coming event I think, they only last for about week or less.
Coin hoarding does cost your account. There is an opportunity cost to not using a certain amount to cycle eggs. Every egg that holds space in your bag is an egg that could be a great mon if removed. Coins not used perform no function and only have a potential use that isn't being utilized. Now, when best to spend them for events etc is the decision.
I would personally decide what amount of coins I'd want to save to be prepared for a good event. Anything over that I would utilize to improve my egg cycling number.
