So I just noticed that I have 25 CSC. I haven't invested in any, so where did this come from? Is this a glitch?

There are currently two video offers that are for 10 CSC and 15 CSC respectively - have you watched either of those?

No - this post is the first time I've heard of them.

Did you get any raffle tickets lately? They can give you csc as well.

No, nothing of the sort.

did you refer someone to join subeta recently ?

Oh, yes I did. You can get CSC for that, then?

25 csc per referral :)

Ah, that makes sense then. Thank you for your help, all of you. :)
