Yep..... 100 % correct.

They were contacted by a good looking female , suggested to deposit , they made money , withdrawal ok .
This continued for a while without any problems.

Then a bigger investment was advised on a different platform , which he did and then the funds were frozen.

Then he was asked to make another deposit (20% of the total value of his accounts from a more regulated exchange) in order to access his funds so they could then be released to his other wallets.

So , I take it that there is absolutely no way for this person to retrieve his funds ?
