Remember that a rapid increase in the price of bitcoin demonstrates that it is bullshit. Unlike stocks or other commodities, bitcoin can only have value as currency, and a currency is only useful if its value is stable. Any movement, down or up, is lack of stability. If the price of bitcoin goes up, that means that anyone who owns bitcoin is stupid to spend it, which makes it useless as currency, and since it has no use or value in any other terms (unlike stocks or commodities), that makes it useless period. That's right: rapid upward movement in the price of bitcoin demonstrates its stupidity.
Stable store of value. Learn it. Know it. Live it.
