What you sent him is already lost, do not send him the $65, you will lose it, it is a scam. Do not give him anything else. He told you that to unlock you need to send $ 65, do not do it.

Someone knows him. He offered me to invest and I sent him 10usdt and according to him I won 450usdt in Coinmarketcap and that I need to send him 65usdt to be able to collect the amount. Does anyone know if it's true? Or was I scammed?
