So I just lost $150 USD in BTC by transferring them to an address that was inserted on the Poloniex balances page. Dumb @$$ me just copied the address and pasted it into Coinbase to xfer, and now it's gone. According to blockchain.info, looks like they have scammed a bunch more folks.
So now I don't know what to do. I guess I have some malware or something, but neither malwarebytes or virus software picked up anything. I'm afraid to do anything relating to crypto now on this computer. Any suggestions as what to do?
