You can say airdrop is easy,  yes it is easy since all you have to do is just fill the registration form and wait for the token to drop but in the real sense of it if you really want a good token worth so much then you will have to consider going for bounties. I believe 90% of people in the crytocurrency market are there for the money involve and not to just catch fun and all, so keeping this in mind then you can I will go for bounty over and over again
