yes, I agree if the airdrop gives us enough income. because I participated in lots of airdrops and it really gave me quite a high income because I experienced it myself. although there are some airdrops that do not pay and are also not listed on the exchange. and we are required to have a lot of patience when participating in the airdrop.
No doubt some airdrops,to say very precisely too little, do provide nice amount when executed/done by serious and talented team. But it doesn't mean all airdrop coins are worthy enough to collect doing different set of efforts and even after collecting those are worthless as it can't be traded nowhere. Maybe almost half airdrop project are being operated by scammers to scam out the participants. So we must be cautious not to fall in their traps.
