This seems to be inaccurate. The twins could choose to simply sell the private key in a private transaction. Assuming they didn't create one wallet with 50,000 bitcoin, they could even sell portions. This gets them paid AND puts the onus for moving the coins to a new address on the new owner. They could exit in 5 minutes if another billionaire wanted their coins bad enough.
> simply sell the private key in a private transaction
Then why not sell it three times to three separate parties? And also keep a copy of the key and engage in some spending from the wallet themselves?
I'm not saying that these particular people would engage in such trickery. But I would be very wary of any proposition to sell me bitcoins in an out-of-band transaction of this kind.
"Typical trading volumes across the major exchanges are only about $2 billion globally"
Sounds like they could just sell ~$20M everyday, which would account for only 1% of the daily trading volume. After ~50 days, they would have cashed out $1B.
That depends on how much of the daily trading volume is wash trading. Bitfinex can just decide to give a couple accounts a pile of USDT on margin and self-trade to stir up a sense of FOMO and convince folks to buy in. It's pretty much free to do if you run the exchange.
