Great writeup. Almost anything written by Matt Levine is worth reading. This is a concise and accurate description of the fun that occurred with Bitfinex's handling of the BCH fork. At least, it's fun if you weren't involved. If you naively held BTC on Bitfinex and were hoping to receive an equal amount of BCH you probably didn't think it was fun. If you carefully read Bitfinex's statements and decided to take advant…
Matt sums it up well in a footnote: Imagine if I announced tomorrow that I had created a new blockchain, called Bitcoin Matt, and that everyone who owned a BTC today will tomorrow own both a BTC and a BCM. Fine, great, you all own BCMs, congratulations. But also anyone short a BTC today will be short a BCM tomorrow, and will be forced to go buy in those BCM shorts. Even with no economic support for BCM -- with nobody…
If on the other hand you short a stock, and a third party says "Hey, I'm going to give everyone who owns this stock on this date a bag of cash!" I don't think that shorts would be obligated to cover that. This is, I guess, like what happened with Dole, except that there the third party was a judge, who has the force of law at his back. And this strikes me as similar to what happened to BTC/BCH, except without said force of law. Wherein lies the ability of someone to compel a BTC short to now owe BCH too? What exactly is it that shorts have agreed upon to return to the longs that they borrowed from, and if it's just BTC, isn't returning a BTC enough? If not, what stops someone else from making their own fork and compelling shorts to come up with that too?
