I'm doing signature campaign and trading. If i stick only on one generating income like signature campaign. I think i won't earn much because there are times that some of the campaign pay only less or the duration of payment after the campaign is long. You are lucky if there are a lot of bitcoin campaign because once you are accepted you have a chance to earn big and it depends on your rank. On the other side with altcoin campaign the only bad side is when the company does not pay their bounty hunter or their ICO is not performing well. That's the reason i don't stick in one job although trading has risk but we can manage it if we are very patience in trading and also control our emotion.
