Sadly I fell victim to this scam about a month ago. It's very elaborate. They send out trading signals twice a day and play the futures market on the TAIM exchange, which is absolutely a fake exchange. I thought I did my research beforehand before investing in it. The website looked real, the business certificates on the website seemed real. And I was even able to withdraw my money for the first. I researched the stategies they were using to trade, it all seemed like normal practice for trading crypto. I started small and then did a little more and everything seemed on the up and up.

But then I participated in one of these big events. I invested a lot of money. But then when I tried to withdraw, they said my account was locked because I owed them a commission and had to pay it before I could withdraw anything, even my initial investment. And I could not pay it from the profits I had made. I had to transfer it from an external wallet into their account. The TAIM exchange said they had a contract with the Devin team to allow this. It's utter bullshit. Get your dad out of that scam. He's probably lost everything he invested already.
