I have created account in localbitcoin.com. Scammer has messaged me in whatsapp and told he is employee of LBTC. 
He has told me about 25% bonus for first time deposit in LBTC.
He has told me that he will generate bonus wallet address. He has mentioned my mail id (wrong mail id as I have other mail id in LBTC) connected to LBTC.
He has given me his BTC address and telling me that it is my bonus wallet address.
He has suggested me to deposit 0.22 btc into bonus btc wallet and wallet will be updated with 0.27 btc.(There is no bonus BTC wallet, it was his wallet)
when i have told him i will complaint to localbitcoin.com and cybercrime department.
Then he sent me mail in the name of localbitcoin support (fraud mail id generated in LBTC) in the wrong mail id.
So please be careful and keep below security into your account
- Don't disclose registered mail id to anybody
- Use 2fa in all exchange and mail account also.
- Don't transfer your BTC/ETH to the account for bonus or 'BTC/ETH Giveaway'.
- Don't be greedy. Nothing is free.
