Calculate Sharpe Ratio for Any Crypto Portfolio
Crypto's returns are big — but so is the volatility. Sharpe ratio is the only honest way to tell whether a portfolio's gains justified the ride. Foliolytic computes it against real Treasury yields and compares you to BTC buy-and-hold, ETH, and the Bitwise Crypto Index.
Why Sharpe Ratio Matters for Crypto
The Sharpe ratio is a single number that answers: for each unit of volatility you endured, how much return did you get above the risk-free rate? It's the most widely used risk-adjusted performance measure in professional asset management, created by Nobel laureate William Sharpe in 1966.
Crypto investors famously ignore it. Most trackers show only percentage gains, which makes a 200% YTD portfolio look brilliant — until you realize it endured an 85% drawdown to get there. The portfolio that returned 100% with a 40% drawdown was the better investment on every professional metric, and Sharpe proves it.
The formula:
Sharpe = (Rportfolio − Rrisk-free) / σportfolio
Annualized portfolio return, minus annualized risk-free rate, divided by annualized standard deviation of returns.
A higher Sharpe means more return per unit of volatility. Below are rough benchmarks for crypto specifically (which runs lower than equity-market Sharpe ratios because of crypto's extreme volatility):
| Sharpe Ratio | Interpretation (Crypto) |
|---|---|
| < 0 | Lost money on a risk-adjusted basis |
| 0 – 0.5 | Underperformed risk-free yields given volatility |
| 0.5 – 1.0 | Below BTC long-term Sharpe (~0.9–1.1) |
| 1.0 – 1.5 | Strong for a crypto portfolio — beats passive BTC |
| 1.5 – 2.0 | Excellent — rare for retail crypto traders |
| > 2.0 | Exceptional, usually reflects a short lucky window |
Sortino — A Fairer Metric for Crypto's Upside
Sharpe's main weakness for crypto: it treats upside volatility and downside volatility identically. A coin that spikes 80% in a week gets penalized for that spike just like a coin that crashes 80% — even though investors want one and hate the other.
Sortino ratio fixes this by only counting downside deviation in the denominator. For a crypto portfolio with asymmetric upside — which describes most winning crypto strategies — Sortino almost always reads higher than Sharpe and gives a truer picture. Foliolytic computes both side by side; a Sortino-Sharpe gap larger than 0.5 means your volatility is concentrated on the winning side.
Compare Against Real Crypto Benchmarks
A Sharpe ratio in isolation tells you little. What matters is whether you beat the lazy alternatives. Foliolytic automatically compares your portfolio against:
- BTC buy-and-hold — the benchmark every crypto allocator is implicitly measured against. Long-term Sharpe roughly 0.9–1.1.
- ETH buy-and-hold — second-most-common passive reference.
- Bitwise 10 Large Cap Crypto Index (BITW) — a professionally-managed, rebalanced basket of the top 10 coins.
- S&P 500 — not directly comparable, but useful context if you hold crypto as part of a larger portfolio.
If your Sharpe is higher than BTC's over the same period, you've done something genuinely hard. If it's lower, passive BTC would have delivered more return per unit of risk — and your active trading or altcoin selection cost you.

Open the AnalyzerFrequently Asked Questions
What is a good Sharpe ratio for a crypto portfolio?
Crypto's high volatility means Sharpe ratios are generally lower than equity portfolios. A Sharpe above 1.0 over multiple years is strong for crypto. Bitcoin's long-term Sharpe (since 2010) is roughly 0.9–1.1 depending on the period. An altcoin-heavy portfolio with Sharpe above 1.5 sustained across a full bull-bear cycle is genuinely exceptional. A Sharpe below 0.5 suggests you took on significant volatility without proportional return — a signal to reconsider your allocation.
What risk-free rate does Foliolytic use?
Foliolytic uses the 3-month U.S. Treasury bill yield at each point in the analysis period, pulled live from its macro-yields database. This is the standard risk-free rate used by institutional fund managers. When Treasury yields were near zero (2020–2021), the subtracted risk-free rate was tiny and Sharpe ratios ran high; at current yields around 4–5%, the bar is higher, which is why recent crypto Sharpe ratios look worse without a change in underlying performance.
Is Sortino better than Sharpe for crypto?
Often, yes. Sharpe penalizes both upside and downside volatility, but crypto's big rallies are precisely what investors want exposure to. Sortino only penalizes downside volatility, so it doesn't punish a portfolio for 40% monthly gains. For crypto specifically, Sortino tends to give a fairer picture. Foliolytic calculates both — compare them side by side. A Sortino meaningfully higher than Sharpe means your volatility is concentrated on the upside, which is good.
How does my Sharpe compare to just holding Bitcoin?
Foliolytic shows a Sharpe ratio for your portfolio, for BTC buy-and-hold over the same period, for ETH, and for the Bitwise 10 Large Cap Crypto Index. If your Sharpe is higher than BTC's, you've outperformed passive Bitcoin on a risk-adjusted basis — a genuinely hard bar to clear. If it's lower, your active trading or altcoin selection hurt you relative to just holding BTC. Most retail crypto investors underperform BTC on Sharpe.
Does Foliolytic support Sharpe for any cryptocurrency or just BTC/ETH?
Any cryptocurrency with at least 30 days of daily price data. Foliolytic tracks 440+ cryptocurrencies with full historical price series going back to each coin's inception. For tokens not yet in the database, Foliolytic fetches history automatically on upload. Memecoins with less than a month of price data can't produce a statistically meaningful Sharpe ratio — the calculation will flag them as insufficient-data rather than return a misleading number.
