It's a scam!

A person I connected with on Shapr is trying to convince me to ‘collaborate’ with them on a Forex investment on Super Binary. Basically I fund the project and they trade on my behalf and we split the earnings. They promised a return of at least 5% weekly. We ran a demo account loaded with $10k of virtual money and they have proven themselves able to make money using it. They promised everything will be done through a broker but now are asking for me to basically give them the log in details to the Binary account so they can trade on my behalf.It all strikes me as incredibly fishy. Is this a normal thing to do in Forex or am I just an idiot? If joint investments are done surely they would be done through a joint account. All of my trading experience has been through Crypto currency only making my own investments, so Forex is completely new to me. However I made a deposit to them and now I can't acces to my account. Can you please help me to this scammers?
