2 ZCL per week x 10 possible weeks (20 ZCL)
So, it means the maximum token rewards we will get are 20 ZCL.
signature codes?
For the signature code, max potential of 30 ( there is a 10 ZCL bonus for the most creative / best signature)
If you take a look at my previous reply, you can see that 20 ZCL has significant potential when distributed. I might be sweating sending out those coins at the end of the bounty.

However, you can also see we give away additional ZCL for lots of things including just being active in the socials. Last week we did our voting for "Best Comments" on Reddit, Twitter and Youtube and there really isn't alot of competition for those yet. Some easy ZCL to be had for those with some initiative.
