I think my mate has been scammed big time and lost all his savings

So this girl added my mate on facebook pretending she is really interested in him, they exchanged messages back and forth for a few days and then she started recommending crypto trading saying she’s been a trader for almost 10 years and she’s worked for some of the biggest finance companies etc she tells him if he follows her advice on when to buy and sell, he can make thousands every week.

Long story short, invested 3k on a trading platform called metapro-fx.com He made £20k within 2-3 days and then further invested further £12k of his savings and supposedly made £100k profit within a week. So now he wants to withdraw the £100k (USDT) profit from the wallet into his bank account, however he needs to pay a 5% fee (roughly 5k) upfront before he can withdraw the £100k profit.

Now he is desperately going round borrowing money from friends and family to raise the 5k fee. What’s the likelihood that he’s getting scammed because he seems to be adamant and completely brainwashed that this is totally legitimate and the reason that girl has been giving him all this trading advice is because she’s really into him and she really likes him. He’s been accusing me of being jealous and a hater every time I tried convincing him this sounds waaaay too good to be true and is most likely a scam. Apparently I’m jealous that he made £100k in a week ????‍♂️
