It's possible to earn 1 Bitcoin in a year with bounty, possible but not easy, you must work very hard to earn it, nowadays bounty is not an easy job, it includes many things and a lot of works to do. I recommendet you join all task in bounty
A lot of requirements, effort and time to do all the task but in the end a great reward of return. You really need patience when you participate into a bounty program but be skeptical in joining because as I said ICO are mostly scam.
