It's simple... If you can only pay them in crypto they are scammers. Offer to pay them through mainstream banks and if they accept this it puts them one rung below total scammers. Remember if you pay them in crypto you will never get it back. For the same reason they can't hack another wallet and get your money back. I'm talking from experience. You can go to tracing agents but they just going to tell you where your money went and that's where it ends. Useless reports. There is a company in Israel that specializes in useless reports and you pay through the nose. That is why they won't recover the money for you because the reports are useless. #justsaying.
