If you have enough budget, just trade on altcoins to get much coins. Because if you want to get it by joining airdrop, maybe you will get nothing or maybe $5 worth of that coin, and i do not recommend to join airdrop, prefer to join on bounty campaign which more promising. But you can't getting coins by joining bounty or airdrop because they have special time to distribute their coins, if you want to get coins everyday, so you must do trading and buy for them if you have much capital remains.
