It's just a matter of being able to choose the right ones. Though it may actually be difficult to identify which are those. But of course, we'll never know which ones are right if we don't jump in. Bounties are still good for me 'coz you could still actually profit from them as long as things go accordingly with the sales and that the token get listed. For airdrops on the other hand, not so good or even practical for me 'coz many of them are just a waste of time. So many airdrops but majority of them are just worthless.
