This forum does allow to earn from social signatures using facebook and twiter, besides those you can join the signatures for posting, with this earnings you can invest at Ico or start trading. I did started with faucets some years ago and nowadays i use my signature earnings a part to trade and im saving the other part for the future.
The only downside to earning with signature campaigns is that it takes you a while to gain ranks and also the spots for good campaigns get filled very quickly, so while signature campaigns are a great way to make some additional money it is really difficult to make any kind of consistent money through them and as such we must be realistic about the earnings we can get with signature campaigns.
In my opinion maybe it takes time to rank up but the salary or the bitcoins that you will gain from the signature campaigns will really worth the time your investing. Aside from joining campaigns you can still focus on your trading job while waiting. Every job offers from the campaigns are really worthy.
