I got in touch with what I'm basically sure is a task scam. The thing is, they gave me money for doing some tasks. I've cashed out over 300€ into my Trust Wallet (about 30 of which were my own at the start). I assume they're building trust and warming me up to deposit a large amount which they won't repay. I've sent them a photo of my passport, signed a contract (they used a fake signature of the company they're phishing as, so I'm pretty sure that doesn't mean anything). They also have screenshots from me using their platform and receipts of transfers I made to them or they've made into my account. My question is, I've made money, I know it's a scam, I don't care about keeping the money, I just want to be safe. Should I send back the money or try to reason with them and see what they say? They don't know I'm suspicious of them.
