The scam project can not be avoided successfully now because it created by clever people – hackers. Yesterday I lost my stablecoin from Matic and BSC. It was a project for claiming free NFT. I noticed late that there is a switch between wallets. I managed to turn it off before connecting to the Ethereum Mainnet
I'm sorry for you, and I hope you can get more results from your efforts, of course you don't give up even though you have been hit by scammers,
and in my opinion we can avoid scammers by analyzing these altcoins,
and if you take part in the airdrop of course you have to really understand the risks because now there are so many airdrops that redirect to our wallet.
