Recently i took part in couple of bounty campaigns,and i though i can earn some decent amount through it...but it was a total waste...i took part in targetcoin and coss ico campaign and after 2-3 months i recieved the bounty which is worth only about 8 USD including both 
it was just total waste of effort and time
it was just total waste of effort and timeWell maybe they gave you right amount of coin and the problem is the value of it. This is normal for the first few months for the price to go down. To solve this set your target price, make sure this target price is reachable by time and by value. If it hits you target price sell it. The key is to wait and be patient.
