...It all just seems fishy to me. I haven’t contacted him yet, but figuring they will want money to get a TVN. Is this normal or does it appear to be a scam?
I think that all this will not end with the provision of TVN and you will be required to deposit either an additional amount of money or provide a seed phrase from your wallet. You have to accept that you have been deceived and if you continue to communicate with them, you will lose even more of your money.
Most of these scammers have really good marketing skills, they will sell their scam to you and make you believe that's the best option for you. If OP still sticks around, they will manipulate him the more into getting more money for things that don't even exist. Obviously, what they would be asking for won't end at just getting a TVN, more issues that requires sending money will come up and if OP doesn't accept now that he has already landed himself in a scam group, the scammers will feast on him till they see nothing left to feed on.
Dear OP, you have already been scammed once, don't let them scam you twice, run away from that telegram group as fast as you can.
