If Tim was a scammer, he would have kept private keys to the PK version, and swept them by now. The fact that that has no happened would make me believe "Never ascribe to malice that which is adequately explained by incompetence". He fucked up the 2FA version. Corrupted, accidentally deleted, or something like that. The 2FA coins are gone, probably lost forever. I could be wrong, but I think its the most logical explanation. Having a DB be both secure, and redundant, is very fucking hard.
It won't come as any surprise to anyone that I believe Tim is a scammer, on some level. All of his actions leading up to this day, the way he went about promoting certain things, his statements about "insurance" for his coins etc, all look scammy IMHO, and I spend a pretty fair amount of time breaking down coins scams in this space. I know what to look for, I see certain things that coin scammers have in common, and Tim meets all of them.
Tim continued to sell coins for several years after knowing of his 2FA coin issue. He promised over and over to make anyone whole if any coins were lost due to him, and he hasn't done that. He stated he stored the private keys for the 2FA coins in a vault bank...isn't it possible he kept all those coins, how would we really know otherwise at this point? Can you still fully/truly tell from the public keys, or is there only a code to check? ( I can't remember fully how this all works, being so convoluted).
If Tim were to sweep the PK coins right now, I'm pretty sure he realizes he'd have to go in full hiding, if he hasn't already. He's already cost at least over a million dollars worth of loss, sweeping the PKs would mean millions more, that takes a scam to a whole nother level. That's why I swept the Titan I have, I don't trust the guy one tiny bit, and my intuition feels like he will try and sweep some of the PK eventually. That's just my feelings and I could be dead wrong and hope I am. He's been anything but straight forward about all this for YEARS...I don't blame you for peeling your coins one bit.
