Excuse my ignorance, but this seems like the obvious solution to me: Distribute 1 BCH to each (actual) BTC holder on the exchange, completely ignore margin orders. So shorts don't owe and also longs aren't credited BCH. Fair and no way to game. Why aren't exchanges doing this?

What in your mind is the difference between "Holders" and "longs"? They're the same thing. Holding an asset is being long on that asset, just as being short on an asset is owing that asset.

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…

Could a similar trick be used by a company to screw over short sellers? Say by issuing a class of shares which are essentially worthless, forcing short sellers to buy it to cover their shorts? Or would a short seller simply "borrow" those shares as well?

Not really, because stock prices are adjusted downwards in case of forward splits or stock dilution etc. If they the diluted shares are "worthless" so to speak then it doesn't matter.

What the real scenario is when there is a spin off where Stock A becomes Stock A + Stock B. In that case short sellers are responsible for the value of stock B. Though no one will try going this route just to screw some short sellers. If the spun off division (or company) is worthless, the stock prices will come around to reflect that and even Stock A's price will suffer from this "trick" used by management.

There's no such thing as "actual" BTC holder. All the BTCs in the exchange are fungible. A holder of BTC doesn't know if that BTC was loaned to someone else or not.

In a sense, what you suggest is exactly what the exchange did: They calculated the number of "actual" BTCs in the exchange, and split the appropriate number of BCHs evenly among everyone.

It is hilarious watching people try to reinvent financial institutions without any knowledge of or respect for history.

Maybe I'm too "left wing", but if you ask me short selling, complex products and high frequency trading are among technological "improvements" that have led actual stock exchange to an ugly mess where biggest profits are made by "scamming" efficiently other users.

Short selling is what keeps the cheerleaders in check.

Short selling is an incredibly important piece of any reasonable stock exchange. It also dates back to 1609 so it's not exactly a new technological innovation. https://en.wikipedia.org/wiki/Short_(finance)

From the very article you reffered to me : Short sellers were blamed for the Wall Street Crash of 1929.[15] Regulations governing short selling were implemented in the United States in 1929 and in 1940.[citation needed] Political fallout from the 1929 crash led Congress to enact a law banning short sellers from selling shares during a downtick; this was known as the uptick rule, and this was in effect until 3 July 20…

If there was short selling that could have been blamed for the crash of 1929 it was what is known as a naked short selling. Since non-market making short selling now requires having a locate, it is impossible to sell short more shares that one can reasonably borrow.

I'm not knowledgeable about BTC; this is the part that confused me. If you short a stock, and it distributes dividends or stock or ponies, as Levine says, you have to return that to the borrower. I'm not sure if this is law or just the overwhelming common practice of the markets, but either way we agree on this. You _could_ devise a short agreement where you say "no distributions are owed," but that's not the standar…

I would check the notes to see what happened with Dole before drawing a conclusion. There is more at stake here than a judge with backing. One of the problems with Dole was tracking shares with DTC - It takes, I think, T+2 for settlement ie I sell you something today it gets updated two days later in DTC. This coupled with day trading and shorts (where btw "borrowing a share" is hypothetical) can cause a lot of headaches. So the solution is? A blockchain which tracks the share count and movement. That is the point being made in the article.

As for the other part. The whole BTC/BCH thing is like a spinoff. And yes the short sellers are on the hook if Stock A tomorrow becomes Stock A + Stock B. Can they say no, well Stock B is more than I paid for A+B combined so I am not paying? Not really because if that was the case it leaves open the door for someone saying - well stock A has appreciated more than I expected so no payout.

Now in case of forks and whether people can be on the hook for the other fork? Well, depends on how famous the fork is really. If it is as famous as BTC cash, well then that is a risk you have to take as a speculator. If not, then why was someone betting on bitcoin going down the drain after the fork? Were they not clear of the implication of the fork taking off? If not, then that's a lesson learned.

To paraphrase Matt Levine - "The basic appeal of the cryptocurrency revolution, to people like me who are not making any money off of it, is that it is fun to watch people rediscover all of the lessons of financial economics, one at a time, in public. "

> me short selling ... are among technological "improvements"

that's why, to protect the pensions and savings of its citizens from a catastrophic collapse in equity markets a couple of years ago, the chinese government decided to ban short selling. up and up and up, baby!

i think the government should go one step further, and prevent anyone from selling stock lower than the price they paid for it. guaranteed profit for everyone!

I wouldn't call your views "left wing", just a bit ignorant of market theory, history, and practice. I mean, the Dutch Tulip Bubble was driven by derivatives (and in particular, a law change forced by the politically connected that retroactively changed some future contracts into option contracts), so if you're looking for some halcyon age prior to "complex products", bailouts, and people using lobbying to reap outsi…

Ok so how on earth does the fact that derivatives permitted the tulip Bubble is an argument in favor of derivatives? It might a question of point of view. Maybe you focus more on tulip frenzy financial opportunities while I focus more on people that have been burned by it... And yeah if you want to trace it back to 1500 no problem with that, old does not always equal good. It like copyright laws written prior to wide…

Simple derivatives like calls and puts are unbannable.

Observe that I can replicate the payoff of a call option by borrowing money to buy the stock [1] or replicate a put by shorting a stock and lending money.

It makes perfect ironical sense too, we should have seen this coming. Developers are some of the best armchair economists, or like to think they are. Add in the libertarian political strain with some VC/startup evaluations and you've got what we have now: an inflated decentralized currency with a market run by a centralized tech company with infighting of developers (miners) over very shaky economics who have formed…

... and this is why I didn't get on the Bitcoin train when I was first fascinated by it in 2009. Too much RonPaulnomics in the community, a refusal to discuss Gresham's law and an unwavering optimism in that transaction costs melt away magically.

Then, me and my intellectualism lost big to the australopitheconomists-with-crypto.
