I have a lot of ce saved up.
And I realized... Because of ce prices going down, my investment of ce is worth a lot less.
So for future reference, I should keep my investments in crowns? Because the way it looks... The ce prices are going to stay down for all of this promo and more.
Yes, the value of your energy goes down when energy prices go down. But then it goes back up, when prices go back up. You want to "buy low, sell high". This is how all markets work. There is no simple formula or recipe for how to do this. If there were, then it would destroy the market.
In order to profit from the market, you need to have some ability or insight that other players don't have, that lets you predict the future better than other players. For example, if you've played the game a while (or have studied the wiki), then you might have a sense for when promotions happen, and what happens to the price of energy during promotions. Or you might follow pre-announcements and rumors on the forums.
For example, in the months leading up to the guild hall update, it was clear that guild halls were going to increase the demand for crowns, causing the value of crowns relative to energy to rise, or in other words causing the price of energy to fall. So many of us stockpiled crowns until the update, and then purchased energy afterward.
I don't have specific comments about this promo, but it doesn't matter, because this promo has already happened. If the price of energy is currently low relative to historical levels, then you should consider buying energy.
Welcome to the Economy system and the Speculative market.
May I recommend you this thread? Use it as a reference to see if it's really worth it investing on Cr or CE. It's up to you and what you believe will happen in the next months.
Who knows? Maybe next week we have another Box promo, setting the CE price even lower, or a Flash Sale, rising it.
