I am new to Bitcoin, and I recently received a Bitcoin transaction on get. The transaction seems legitimate, because the customer of mine showed me a transaction receipt from an ATM and my wallet address written on it, but they require me to log in their website, create and account and verify my ID & SSN in order to claim the bitcoin to my wallet,
You cannot receive bitcoins to your wallet if you have not created an account, it's definitely a scam. For you to receive Bitcoin to a wallet you need to have created it and gotten a seedphrase which you can store, this generates public keys and then addresses you can send to someone and they send bitcoins to you there.
