I think you can earn way more joining a signature campaign, search for signature campaign and apply since your rep/rank looks clean I think you should be able to join one if not just wait for a new signature campaign to start and apply. 1year contract is way too long even though your wage is quite low.

I am trying to join bitvest signature campaign now. Also I decided to grow up my account rate to sr. member and then join to bitcoin mixer campaign. I decided to not sell my signature just for 100$ as I can earn it in 1 month with signature campaign. That was not smart decision to open this thread. Thank you all who gave me good advices.  I close it.
