Never join an airdrop launched by a project that has not been released or has not been tradeable, especially if they ask for something from you as a participant, be it eth for fees or even KYC, because anyone can do something like that.
Airdrops are actually airdrops launched by a project that is already successful and can already be traded, they usually do it for some reason like as a gift to their token holder or something else.
well what you say I really agree, especially when there is an airdrop in the telegram bot, it is certain that 99% will lead to a scam because until now no telegram bot has been successful because there are frequent errors, it's better to participate in the bounty campaign according to my scam risk is not very high.
