Why a savings plan
Buying a fixed amount at fixed intervals means you never have to guess the right moment. You buy more Ether when it is cheap and less when it is expensive, and end up with an average price.
Buying more when it is cheap
The value-weighted plan saves the same amount every period but spends it according to where Ether sits between the bottom and the top line: 4× at the bottom, 1× at fair value and ¼× at the top, smoothly in between (multiple = 41 − position/50). Money it doesn’t spend stays as cash and is used later, when Ether is cheaper. It never spends more than it has saved.
Questions
What is DCA?
Dollar-cost averaging: buying a fixed amount at fixed intervals, whatever the price.
Has it worked for Ether?
For $100 a month since 2020: $8,300 paid in, $14,626 today. Of the start years 2016–2025, 5 are in profit and 2021, 2022, 2023, 2024, 2025 are below what was paid in.
Weekly or monthly?
Over several years the difference is small. Weekly smooths the entry slightly; monthly means fewer purchases and fees.
Does value-weighted DCA do better?
It finished ahead of plain DCA in 10 of 10 start years. This flatters the rule, because the bottom and top lines were fitted to the same past prices: the direction is plausible, the exact numbers are optimistic.
