So, before we get into the meat of things, it's important to talk about exactly what a currency event is. So, what is a currency event?
At its core, a currency event is an Weekly Event that you will complete by spending any of your non-standard Weekly Event resources.
The standard rotation of includes the Gem Event, Weekly Events Event, Summon Event, and the Get Lucky Event. These events essentially reward you for spending Upgrade, Gems, Kappa Scrolls, and Get Lucky Chips. TriHard Scrolls
Unlike your standard , the currency events reward you for spending most of the other resource types in Clash of Streamers. For example, by spending Weekly Events, you will be progressing through the Athene Coins Event. Athene Coin
However, there is one primary difference between the standard and currency events: unlike a standard Weekly Event which needs to be completed during the week it is active, you can spend any of your currency event resources at any time and you will always be progressing through the respective currency event.

Essentially, you can still spend your even when the Athene Coins Event is not active. When the Athene Coin Event appears in the special event rotation, you will be rewarded for how many Athene Coin you ended up spending. Athene Coins
For example, if you spent a total of 300 , you will receive the rewards for the first two tiers of the event. Athene Coins
The currency event (like the Event) will only ever reset once you have fully completed it. Athene Coin
You can never miss out when it comes down to the currency events! If you play Clash of Streamers long enough, you will eventually complete each currency event and receive the final rewards of a legendary event artifact, shiny legendary pet, and high level hero. Once you have completed a currency event, it will have its progress reset back to 0, and you can begin the process again.
This is the essence of how currency events work. You spend different currencies, and gradually earn progress towards the respective currency event.
However like I mentioned above, not every currency has its own currency event. The standard Weekly Event resources do not have their own currency events. So, the question becomes, what currencies do have their own currency events?
