Hype TestedDCA vs lump sum: which wins for Bitcoin?
Short answer: No edge: the difference could easily be luck.
Dollar-cost averaging (buying a fixed amount every month) is often called the safe way to buy Bitcoin. We compared it with investing the same total all at once on the first day.
The rule we tested: Invest a fixed amount in Bitcoin every month instead of all at once.
Across 62 results the average difference was -14.60%, inside the noise band of ±29.29%. We can't tell it apart from luck: no measurable edge.
| $100 every month | Same total on day one | |
|---|---|---|
| Total return | +94.6% | +109.3% |
| Per year | +13.8% | +15.4% |
| Worst drop | -51.0% | -76.7% |
| Volatility | +30.0% | +52.0% |
How we tested it
We buy Bitcoin for $100 on the first trading day of each month (62 buys, $6200 in total) and compare with investing the same $6200 on the first day. Money not yet invested sits in cash at 0%. Both lines show value per dollar of the total.
Period 2021-08-01 → 2026-09-28. Costs: 0.10% per round trip. Data: Uniswap v3 pool state on Ethereum mainnet, computed by Hype Tested, up to 2026-09-28. Engine 0.1.0.
What this doesn't tell you
- Past results don't predict future results.
- Trading costs are an estimate (0.10% per round trip). Spreads and slippage can be higher, especially for small stocks and crypto.
- Taxes are ignored. Frequent trading usually costs more in tax than buying and holding.
- Crypto prices are computed by us from Uniswap v3 trading pools on Ethereum: a 30-minute average ending at midnight UTC. They are quoted in USDC, a dollar-pegged token that briefly traded near $0.88 in March 2023, and "BTC" is WBTC, a token backed by bitcoin held by a custodian.
