Good airdrops is gone, year of 2017 is a wonderful dream for us if you looking for the past event, that time we only need to fill the form and give them our address to receive free gifts. I think airdrop is already dead now, but it'll be profitable again if altcoin price pump like 2 year ago.
Indeed airdrops and prizes in 2017 are glorious periods where we can make hundreds of dollars, but it's all over. There are no more airdrops that generate hundreds of dollars this year, 2018 many dead projects and constant fraud against ICO, 2019 is still the same as many plagiarism scamers copying white papers and stealing team pictures to outwit investors, so I think scamer still often happens. and currently there are still many projects that have not been as successful.
