Here's my theory:

At some point in 2015, after his interaction with me, Tim realized he could simply deny redemption on any 2FA coin that had been resold, as the new owners would not have access to the original email/password associated with the coin, and may not even have known the coin was 2FA, like me. I would have essentially no recourse other than criminal/civil court action, and at that time 1BTC was only $400 so it wasn't worth really even going to court across state lines for a small claim... I suspect he spent the bitcoin that was behind the coin that I owned, if there ever was one, after he denied redemption to me.

Eventually he needed money to pay for medical or whatever, and he started cashing out and spending all the bitcoin associated with 2FA coins, and stopped doing 2FA coin redemptions.

This is not a matter for small claims court, any longer. It might have been in 2015, but now Tim owes me personally around $30k. I mean he's avoiding a guy with 15 BTC locked up in 2FA coins, that's like $1M at the top of the last peak. I think it's only a matter of time until the police and/or the feds get involved now, this is turning into a large-scale scam, maybe one of the largest scams ever on this site, with many victims, me included.

Honestly I hope this doesn't ruin Tims life and he finds a way to make all the coin holders whole again, and I hope his health recovers too. Cheers all.
