I also heard how when people receive an airdrop or another term, they immediately sell it for btc. Can someone explain this process as basic as possible?
it depends mate if the token from airdop already has value. Because sometimes there's is no value and need to hold for long time before to sell ., and sometimes even it already has value mostly is keep holding especially if the team behind is good and experts wherein for sure the token value will grow more in the future .
