The scammer is impersonating himself as Toray Kortan.
Telegram group he is using to scam people is: CRYPTO OPTIONS MINNIG GUARANTEE100
He asks you invest $100 worth of bitcoin and you get high returns within 24hrs. Once you invest, he shortly shares with you account details to log in to the portal and confirm your investment. Shortly afterwards, he asks you to transfer an additional bitcoin worth $200 because the minimum investment is $300. This is what he claims will unlock your profits. If you refuse to add more funds he tells you your funds are frozen and you can't get them back. And that is how you lose your money. A big scammer and very rude once you engage him to return your funds
