Help to convince colleague about scam AI trading site

Hi all,

My work colleague has been using a company called Trusted Assets (https://trusted-assets.com/#service) and says they have put in a small amount of money to start with a few months back and it’s now worth about 20 times that.

I’m pretty sure it’s a scam site and they’ll never see the money back but need some help convincing them to steer clear. Apparently someone from them calls each week trying to convince them to take out money from the bank or get a loan to add to it!

The Trustpilot reviews mostly are 5 stars but I’m convinced those are all made up.

Anyone personal experience or can link to some articles that show how much of a scam it is?

Thanks!
