Is Siezxcion a scam, or is it legit?

I met an online friend on Instagram who claimed to be a Taiwanese working in Hong Kong. I thought we could make friends and added him as a friend on Line. One day, he told me that he had made a lot of money with CITIC SECURITTIES and that he would take me to operate with him someday. I did make money and successfully withdrew funds the first time we operated together, so I believed him. The second time I operated together, he asked me to ask the customer service if there was any new member activity, and said that he wanted to pool money with me to earn a gift. Because the other party did take a screenshot of the deposit record to my account, we pooled money together. When the amount reached the activity requirements and I received the gift, my withdrawal application was rejected. After asking the customer service, I learned that because my account had a record of two people depositing funds (me and the online friend), there was a suspicion of money laundering, and the account had been frozen. I had to pay a risk control fee to unfreeze the account. When I explained this to the online friend, he said that we could only pool the risk control fee together to get back the money we invested. Then he took the initiative to deposit a sum of money. Later, I saw similar cases on the Internet and realized that I was defrauded. Please note that CITIC SECURITTIES is fake!
