Shouldn't we be able to see on the blockchain if these coins have been spent again? That would be interesting to see. Also, I would not know what to do with 65

Shouldn't we be able to see on the blockchain if these coins have been spent again? That would be interesting to see. Also, I would not know what to do with 650k hot bitcoin. I think nobody is currently tracking "taint" and would refuse tainted BTC. But I would have trouble liquidating much less. It seems even the anonymous "guy in the park" wants to see documentation nowadays. Governments have really stepped up their anti-laundering game.
