お金を引き出すことができませんか？私は詐欺されていますか？

知人からMT5を紹介され、GSM証券で取引して利益が出たので、出金しようと思ったのですが、保証金が必要と言われて7228USD払ったのですが、お金が振り込まれませんでした。他にもMT5をやっている人がいますが、デポジットは払いませんと言われましたが、これは詐欺ですか？

以下は原文です。

Unable withdraw money? Am I being scammed?

I was introduced to MT5 by an acquaintance and traded at GSM Securities and made a profit, so I thought about withdrawing money, but I was told that a security deposit was required, and I paid 7228 usd, but the money was not transferred.There are other people who are also playing MT5, but I was told that I would not pay the deposit, is this a scam?
