They just using people to have a free advertisement thus helping them to have a token circulation in the market. Airdrops before are literally a free money but today it's literally a shit.
You guys shouldn't waste time and effort joining those scam airdrops and besides that will just cost some bucks, if you're lucky enough but if not, those tokens will be just a token of appreciation.
yes I agree that there is currently no promising airdrop, different from the previous year and I remember Stellar who was a big success with the airdrop. airdrop is currently just a waste of time and with requirements that are so complicated that I don't want to join in there.
