This is worth your time. Just in case you’re tempted by the greatest and stoopidest ponzi scheme in history:
This discussion applies quantitative finance methods and economic arguments to cryptocurrencies in general and bitcoin in particular —as there are about 10, 000 cryptocurrencies, we focus (unless otherwise specified) on the most discussed crypto of those that claim to hew to the original protocol  and the one with, by far, the largest market capitalization.
In its current version, in spite of the hype, bitcoin failed to satisfy the notion of “currency without government” (it proved to not even be a currency at all), can be neither a short or long term store of value (its expected value is no higher than 0), cannot operate as a reliable inflation hedge, and, worst of all, does not constitute, not even remotely, safe haven for one’s investments, shield against government tyranny, or tail protection vehicle for catastrophic episodes.
Furthermore, there appears to be an underlying conflation between the success of a payment mechanism (as decentralized mode of exchange), which so far has failed, and the speculative variations in the price of a zero-sum asset with massive negative externalities.
Going through monetary history, we also show how a true numeraire must be one of minimum variance with respect to an arbitrary basket of goods and services, how gold and silver lost their inflation hedge status during the Hunt brothers squeeze in the late 1970s and what would be required.
Happy reading, hodlers. Full note.
