Bountying or airdroping is very useful because you should learn to distinguish between good projects so you can make a small contribution and refer people around the good projects. Do not auto click on bounty without thinking about it
Becoming a bounty hunter is very different than to try to collect airdrops, in the surface it may look the same but taking into account all information that I have gotten through the years it seems that becoming a bounty hunter may seem to be a lot more work but the rewards are real but when it comes to airdrops you do not really know if you are going to get the coins or if the coins are going to have any value.
