It's been a long time since I read Taleb's Antifragile, although the book is still sitting within my eyesight now up there on my bookshelf. It looks like we do not disagree re BTC and gold being antifragile to the mainstream financial system
Gold has long been considered a last-ditch asset, so to speak, an investment of last resort, even though it hasn't been tested in this role for ages. But it was BitMEX's insolent market manipulation and how quickly Bitcoin rebounded that made me think of it as an instance of antifragility revealing itself
My explanation is simple, though I'm not sure if it can be equally applied to the Mt.Gox failure. Some people probably lost millions due to the abrupt price crash (just in case, I've witnessed the whole process with my own eyes), but whichever way or angle you look at it, it was not Bitcoin's fault
And this is what distinguishes it from, and contrasts with, stocks and the stock market
