In this video, I discuss whether Bitcoin is too volatile to ever become money. I conclude that it is not.
One source of Bitcoin's fiat price volatility is its relatively small market cap, compared to large global assets like gold, stocks, bonds, and real estate. These large assets are like the ocean, while Bitcoin is like the swimming pool whose levels rise and fall markedly when even a small amount of the ocean water enters or leaves the swimming pool.
Bitcoin's volatility has been decreasing over time (taking a similar path to large tech stocks, whose volatility has also gone down over time as their product adoption and market cap have gone up), but its volatility could skyrocket when we reach the final death throes of fiat money.
In Weimar, the end goal of physical gold priced in Papiermark was inevitable, but the actual path was extremely unpredictable and volatile, which precluded the use of leverage or timing the market.
Warning: keep only as much in fiat as you are willing to lose.
