Bitcoin Hard Fork Predictions

Tomorrow there is scheduled to be a hard fork of the Bitcoin blockchain and network. There’s a fair amount of uncertainty over what will happen. The hashrate is unknowable until the fork occurs. The price seems to be around 10% of the price of Bitcoin. However, there aren’t too many exchanges that will be accepting this currency, and there are even fewer places you can actually spend it.

I’m going to make some predictions about it to put on record what I think is going to occur and to see how correct or incorrect I end up being.

  1. There will be a Bitcoin Cash block mined before 12 AM August 2, US Eastern time: 80%
  2. The price of Bitcoin Cash at 12 AM August 2, US Eastern time will be <10% of Bitcoin’s price: 70%
  3. The price of Bitcoin Cash on August 5 will be < 10% of Bitcoin’s price: 90%
  4. The price of Bitcoin Cash on September 1 will be < 10% of Bitcoin’s price: 90%
  5. The value of all transactions of Bitcoin Cash around September 1 (maybe averaged over a week?) will be < 10% of the value of all transactions in Bitcoin: 95%

I have mixed hopes for the success of Bitcoin Cash. On the one hand, I wrote previously that if the two factions in Bitcoin split, we could have a competitive market showing which rules were better. However, due to network effects, I still don’t think it could happen and be very successful. Supposing it did succeed though (had a pretty high market price), what would that mean? I suppose it would mean forks would become more common. That might be better for competition, but not for stability of the currency.

Ultimately, the idea that it would be fairly easy to make a successful hard fork of Bitcoin would be pretty devastating to Bitcoin’s health. It would mean consensus doesn’t mean much, it would mean the Bitcoin community could splinter pretty easily, which would therefore mean Bitcoin’s usefulness as a currency decreases as each part of the community would be using their own forked blockchain and coin. Something like sidechains seems like a much better implementation of this idea.

I should probably also disclose that I do not have much faith in the current governance model of Bitcoin Cash, and that does concern me a bit as well. I hope that hasn’t clouded my judgment of the actual technological and economic implications, but only time will tell if my predictions are true.

2017 Predictions

It’s fun to have opinions, and it’s easy to craft a narrative to fit your beliefs. But it’s especially dangerous to look back at events and place them retroactively into your model of the world. You can’t learn anything if you’re only ever looking for evidence that supports you.  However, if you try to use your model of the world to create testable predictions, those predictions can be proven right or wrong, and you can actually learn something. Incorrect predictions can help update our models.

This is, of course, the basis for the scientific method, and generally increasing our understanding of the world. Making predictions is also important for making us more humble; we don’t know everything and so putting our beliefs to the test requires us to reduce our certainty until we’ve researched a subject before making baseless claims.  Confidence levels are an important part of predictions, as they force us to think in the context of value and betting: a 90% confidence level means I would take a $100 bet that required me to put up anything less that $90. Moreover, it’s not just a good idea to make predictions to help increase your knowledge; people who have opinions but refuse to predict things with accompanying confidence levels, and therefore refuse to subject their theories to scrutiny and testability, must be classified as more fraudulent and intellectually dishonest.

First let’s take a look at how I did this past year, and see if my calibration levels were correct. Incorrect predictions are crossed out.

Postlibertarian Specific

  2. Postlibertarian Twitter to have more than 240 followers:  70%
  3. Postlibertarian.com to have >10k page loads in 2016: 50% (had 30k according to StatCounter)
  4. The predictions on this page will end up being underconfident: 60%

World Events

  1. Liberland will be recognized by <5 UN members: 99% (recognized by 0)
  2. Free State Project to reach goal of 20,000 people in 2016: 50% (occurred February 3rd)
  3. ISIS to still exist: 80%
  4. ISIS to kill < 100 Americans 2016: 80% (I think <100 were killed by any terrorists, fewer in combat)
  5. US will not get involved in any new major war with death toll of > 100 US soldiers: 80%
  6. No terrorist attack in the USA will kill > 100 people: 80% (50 did die in the Orlando shooting unfortunately)
  7. Donald Trump will not be Republican Nominee: 80% (whoops)
  8. Hillary Clinton to be Democratic nominee: 90%
  9. Republicans to hold Senate: 60%
  10. Republicans to hold House: 80%
  11. Republicans to win Presidential Election: 50% (I predicted in December, Nate Silver had Trump at 35% the day of, who’s a genius now??)
  12. I will vote for the Libertarian Presidential Candidate: 70% *
  13. S&P 500 level end of year < 2500: 70%
  14. Unemployment rate December 2016 < 6% : 70%
  15. WTI Crude Oil price < $50 : 80%
  16. Price of Bitcoin > $500:  60%
  17. Price of Bitcoin < $1000: 80%
  18. Sentient General AI will not be created this year: 99%
  19. Self-driving cars will not be available this year to purchase / legally operate for < $100k: 99%
  20. I will not be able to rent trips on self-driving cars from Uber/ Lyft: 90% **
  21. Humans will not land on moon by end of 2016: 95%
  22. Edward Snowden will not be pardoned by end of Obama Administration: 80% ***

*I didn’t personally vote for the libertarian candidate, but I did trade my vote, resulting in Gary Johnson getting two votes more than he would have had I not voted at all. I’m counting this as at least a vote for Johnson.

**Technically, I am not particularly able to get a ride on a self-driving Uber because I don’t live in Pittsburgh, but I don’t think that’s what I meant. I also didn’t expect any self-driving Uber rides to be available anywhere, so I’m counting it against me.

***Obama still has a few weeks to pardon Snowden, but it’s not looking good

So let’s take a look at how I did by category:

  • Of items I marked as 50% confident, 3 were right and 0 were wrong.
  • Of items I marked as 60% confident, 3 were right and 0 were wrong.
  • Of items I marked as 70% confident, 4 were right and 1 was wrong.
  • Of items I marked as 80% confident, 7 were right and 2 were wrong.
  • Of items I marked as 90% confident, 1 was right and 1 was wrong.
  • Of items I marked as 95% confident, 1 was right and 0 were wrong.
  • Of items I marked as 99% confident, 3 were right and 0 were wrong.

As you can see from this data graphed, I have absolutely no idea what I’m talking about when it comes to predictions.

You’re supposed to be as close to the perfect calibration line as possible. The big problems are that I only had 2 or 3 predictions for the 50%, 60%, and 90% confidence intervals. For example, my slip-up on predicting Uber wouldn’t have self-driving cars this year means I was only 1 for 2 on 90% predictions. Clearly I need to find more things to predict, as I had 5 and 9 predictions for the 70% and 80% confidence levels, which were right about on the mark. Luckily for next year, I have almost double the number of predictions:

2016 Predictions

How confident should we be? People tend to be overconfident.  One way to figure out if our confidence levels are correct is to test our calibration levels by making predictions and seeing how many of them pan out. Inspired by Slate Star Codex’s predictions, here are my predictions and accompanying confidence levels. For the sake of convenience I will choose from confidence levels of 50%, 60%, 70%, 80%, 90%, 95% or 99%. All predictions are by December 31, 2016 unless noted otherwise.
