Spark snapshot have been taken and you can check your wallet is available to received spark token or not because I got link and just put your xrp adress then will show hoe many spark coin do you get. I don't know about when spark coin distribution started because depend which one exchange do you hold your coin because not all exchange have the same time for distributing spark token. But just received 20% reward allocation at the early distribution of spark coin and you waiting more than few month to received complete it.
