Title: Arbitrage Black Hole Exchange Post by: TheButterZone on March 14, 2017, 02:11:14 AM USD/BTC ATH (AFAIK): GDAX @ $1360/BTC
Billionaire/trillionaire buys out an existing exchange like Bitfinex, Bitstamp, or makes a new one that has practically no barrier to getting funds in or out. Sets a 21 million BTC bid wall at USD $1359.99 ($28,559,790,000). It is now the arbitrage black hole exchange. How long would it take for all other exchanges to get in sync, as the BTC is pulled from other exchanges into the event horizon of the black hole, and everyone gives up trying to bid for any less than that? Title: Re: Arbitrage Black Hole Exchange Post by: jaysabi on March 14, 2017, 03:02:58 AM I imagine that wouldn't happen at all. It would set a price floor and bitcoin would quickly start trading above that. The price in this hypothetical isn't so much higher than what bitcoin is currently trading at that it would create a vacuum that sucks money out of other exchanges. A lot of traders and holders expect bitcoin to reach that price anyway, so there's no reason for people to think it's such a great price that they need to take advantage of someone willing to buy at that price. Plus, the more people take advantage of the buy order and sell to him, the less bitcoin there is trading, and the higher the price goes as other buyers have to compete for a smaller pool of coins. I imagine the price floor trickles into the other exchanges within a day at most. More likely a few hours.
