$50 a month, five years
Five years is not a long time in markets. It is also long enough that the median Bitcoin holder reading this has owned coin for less. This run deploys $50 a month — about a movie ticket and a coffee — across the trailing sixty months. The amount is on the low end of plausibility; the cadence is on the low end of friction. The output is what happens when a small commitment runs uninterrupted through one halving cycle and the first months of the next.
