Nothing much but isn't it considerably more of a stretch? A $1000 coin was achieved off the back of a few hundred thousand enthusiasts using comedy exchanges run by children and crooks.

$80,000 would need a decent chunk of global wealth being convinced to pour into it and stay there. It probably wouldn't actually require that much USD in global terms, maybe $100-250 billion of direct expenditure to push it that high but that's still far from chump change.

Possible but far more difficult to achieve.
