When i submitted for the sig campaign i have checked up the website, it seems pretty legit and they got a lot of options to play with . What i liked the most is the fact that you'll be playing with coins to gain actual bitcoins .
They have hired a serious and trusted manager to manage their bounties and have actually bought ad space on the forum so these people spending all of this money on ads won't ruin their reputation to scam some coins from random people .
