Accidentally encountered an investment scam recommended by a netizen

i met an online friend on internet tantan. we were like friends at first, nothing unusual. then we slowly started chatting about investments. i was worried at first, but then he introduced the max app first, and after getting to know it, i confirmed that it was really, i have no doubts. afterwards, he told me that investing in the british Exchange is safer now, because the previous max was real, so i had no doubts. i just searched online and found that it was a real trading system. unexpectedly, he gave me the link to the british Exchange turned out to be fake, and the app image i downloaded was no different from the real one. later i thought it was not real and wanted to withdraw money, but the Exchange asked me to pay a 1:1 deposit first. i thought in the regular max system, only the handling fee will be deducted for withdrawal. how can it be possible to pay a deposit? after constant inquiries, it is found that this is a fake system, resulting in the inability to get the funds back.
