Someone on Face Book said I could earn free crypto by appying for an airdrop. He told me to download Blockchain from app store to my phone. I did this and created my account with a password. I also created my 12-word phrase. I was then told to go to: https://www.blockchainairdroptechnology.com/ This site then asked me to type in my 12-word phrase to receive my free crypto. Is this a safe thing to do? Is this a potential scam?
