He is a fake account manager. He is Alexzander O Morris in facebook (this is not his real name) pretending to be someone else. I somehow found his whatsapp number +234 811 525 2879, which is based in Nigeria. He has a scam website as well: btcoptionprofit.com and an email he used for modus: [email protected]. Please report this. After paying him a large amount of money, he will just ignore all your messages and email.
