Thanks to you and your team.

Will be waiting patiently for the bounty payment as promised.
Going to be removing the signature now and good luck to everyone in collecting your ethbits into ethereum!

Sig campiagns has also ended but is their any official announcement that we can remove signatures?
I think, you will be. According other campaign it's not necessarily wear the sig code after the ICO over.
ICO is now over. sig campaign too!
Thank you to all for your participation!

I advice everyone not to remove signature till official announcement.
