#platform-migration-fee

My unregulated 'broker' EuroFX is demanding a 'platform migration fee' to release my profits. Scam?

Hey everyone, feeling pretty stupid right now. I got lured into this forex trading thing by some ad on Instagram, and it led me to a 'broker' called EuroFX. At first, everything seemed great. I put in about £2k, and watched my balance grow, supposedly. Then I tried to withdraw a small amount – maybe £500 – just to test the waters. They approved it, but then said I needed to pay a 'platform migration fee' of 15% of my balance before they could process the withdrawal. They're saying they're upgrading their whole system and need this fee to transfer my 'assets' over. This sounds totally fishy to me. Has anyone heard of this before? Is this even a real thing in forex trading? I'm worried I'm about to lose everything.
