Does buying the dip work on Bitcoin?
Short answer: Too few results to tell either way.
"Buy the dip" is the most repeated advice in crypto: wait for a big drop, buy, and ride the bounce. Here is what it actually did, compared with buying on any day and holding just as long.
The rule we tested: Buy Bitcoin after it drops 20% from its 30-day high, hold 30 days.
Only 12 independent results, which is too few to tell skill from luck.
| Buying the dip | Holding Bitcoin | |
|---|---|---|
| Total return | +6.5% | +109.3% |
| Per year | +1.2% | +15.4% |
| Worst drop | -23.3% | -76.7% |
| Volatility | +18.5% | +52.0% |
How we tested it
A dip is a close at least 20% below the highest close of the previous 30 days. We buy at the next day's close, hold 30 days, one trade at a time. Each trade is compared with buying on any day of the same period and holding just as long (+2.0% on average), which is the fair test of "the dip is a better time to buy".

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.
- There are fewer than 30 trades, so luck can easily explain the result.
