I personally think that bounties can be regarded as the best way to earn cryptocurrencies, unlike holding, where you don't even have the assurance that the coin will raise in value, you might find that you are holding on to something that will end up being worthless. With bounties is different, you can earn a lot of coins within a very short period of time, participate in different bounties and earn different coins. I consider bounty campaigns similar as a investing in ICOs. I wouldn't say airdrops are best since most of the give away coins are shxxtty and dont go anywhere in value, I have been holding on to some and now it becomes more like I am waiting for them to drop to zero. im doing this to gather some point of view that can be useful to other lets exchange point of view
