avoid airdrops that require you to send a certain amount of BTC to withdraw your prize, most likely airdrops like this are scams.
it is no longer a possibility that it is definitely said to be a scam, those who still send a certain amount of money must first learn what airdrop means. Actually, the airdrop doesn't have to do several tasks such as following Twitter, subscribe to YouTube or others. The real airdrop is just filling out a form or just giving our wallet address and it's all free
It does not allow if there is an airdrop asking for a certain amount of eth for their account. This is a lot going on in airdrop at the moment.
And most beginners follow those rules. So instead of getting rewarded for free, instead they lose money.
Very few airdrops are valid at the moment, which really rewards them without having to do the job.
The number of airdrops out there is very much or in this forum in the bounties section we should be able to choose an airdrop that does not fool us.
