I don’t really think disclosure posts are particularly necessary — it’s better to assume everyone has undisclosed interests and biases and judge what they say and do on its own merits. But in the event they are a good idea: financially, I’ve got as yet unvested stock options in Xapo which I plan on exercising and hope will be worth something someday, and some Bitcoin which I’m holding onto and hope will still be worth something some day. I expect those to be highly correlated, so anything good for one will be good for the other. Technically, I think Bitcoin is fascinating, and I’ve put a lot of work into understanding it: I’ve looked through the code, I’ve talked with a bunch of the developers, I’ve looked at a bunch of the crypto, and I’ve even done a graduate diploma in economics over the last couple of years to have some confidence in my ability to judge the economics of it (though to be fair, that wasn’t the reason I had for enrolling initially), and I think it all makes pretty good sense. I can’t say the same about other cryptocurrencies, eg Litecoin’s essentially the same software, but the economics of having a “digital silver” to Bitcoin’s “digital gold” doesn’t seem to make a lot of sense to me, and while Ethereum aims at a bunch of interesting problems and gets the attention it deserves as a result, I’m a long way from convinced it’s got the fundamentals right, and a lot of other cryptocurrency things seem to essentially be scams. Oh, perhaps I should also disclose that I don’t have access to private keys for $10 billion dollars worth of Bitcoin; I’m happily on the open source technology side of things, not on the access to money side. Of course, my opinions on any of that might change, and my financial interests might change to reflect my changed opinions. I don’t expect to update this blog post, and may or may not post about any new opinions I might form. Which is to say that this isn’t financial advice, I’m not a financial advisor, and if I were, I’m certainly not your financial advisor. If you still want financial advice on crypto, I think Wences’s is reasonable: take 1% of what you’re investing, stick it in Bitcoin, and ignore it for a decade. If Bitcoin goes crazy, great, you’ve doubled your money and can brag about getting in before Bitcoin went up two orders of magnitude; if it goes terrible, you’ve lost next to nothing. One interesting note: the press is generally reporting Bitcoin as doing terribly this year, maintaining a value of around$7000-$9000 USD after hitting highs of up to$19000 USD mid December. That’s not fake news, but it’s a pretty short term view: for comparison, Wences’s advice linked just above from less than 12 months ago (when the price was about $2500 USD) says “I have seen a number of friends buy at “expensive” prices (say,$300+ per bitcoin)” — but that level of “expensive” is still 20 or 30 times cheaper than today. As a result, in spite of the “bad” news, I think every cryptocurrency company that’s been around for more than a few months is feeling pretty positive at the moment, and most of them are hiring, including Xapo. So if you want to work with me on Xapo’s backend team we’re looking for Python devs. But like every Bitcoin company, expect it to be a bit weird.
