For me, I do trading, airdrops and bounty. I don't earn that much in trading especially some altcoins are down. In airdrops, it depends how the token and ifnits really working ICO. I also experienced and invested in a scam ICO. Too bad for me but it was anlesson learned. Amd also in bounty, some are active for a few months but later part, will stop and postponed their ICO. Cryptocurrency must need to be studied and do research first before investing.
