Energy survey

How do you USUALLY purchase Crystal Energy?
a. With Crowns
b. With real money
c. Mixture of both
Personally, for my cheap ass, it's A.
b.
Play once a night, use CE to pay for crafting when I have the materials. Just hit T3.
after playing the game for awhile, and finding that i wished to support it, and the developers in their endeavor, I made one big purchase, and use it somewhat sparingly. I supplement with crown purchases now. so... both.
a.
I would be willing to make occasional purchases with real money if there was some type of card I could buy at stores.

C.
Purchased 17,000 CE a while ago. Spent 10k of it on revives, crafting, and trading. Nowadays I try to purchase my CE with crowns.
But otherwise A. And I spent my purchased CE crafting.

I do a bit of both, but I prefer A due to lack of money most of the time.

I will start buying energy with real money once 3-Rings devs release a 5* recipe for the Spur series or new bonus content (Like story missions or other things that will make the game less shallow). Because so far, I currently earned all 5* gear (exept for the Winmillion (of course) and the shield (I use the swiftbuckler shield)) that I wanted, that I bought with using regular in-game money before the market started getting insane. I never spent single dime on this game yet.
Overall, and so far. My answer is
A

But i had a large winfall of Real money CE.
Now i primarily purchase CE by crafting equipment selling it for CE. I think maybe this should be listed as a 4th option. It's kinda an extension of crowns, but not entirely, since many most mats i farm. So, in a sense, i am purchasing ce with ce---the primary cost of crafting. As well as a time investment for 4* or above.
C Though if the market keeps trending the way it's going I may have to go entirely B, and just run a little bit a night.
a.
I am willing to spend 10 000 crowns in the near future for 100 Crystal Energy if the market crashes...
