Portfolio simulator

Benchmark. The portfolio is compared with a holding entirely in Bitcoin, held throughout the period. The benchmark is a measurement reference, not a statement of preference: there are periods in which the diversified portfolio outperforms it, and the tool shows them.

Data. Daily price series provided by CoinGecko, updated once a day and limited to the last ten years. For more recent crypto-assets the series starts from the first date available. The selected currency determines the denomination of the initial capital and all monetary values; percentage returns and risk-return metrics remain unchanged.

Correlations. Computed on weekly log returns with a Sunday close, over the entire selected period. The reference is the non-Bitcoin component of the portfolio, renormalised within itself, so that the value measures asset selection rather than the weight of Bitcoin. With a portfolio held entirely in Bitcoin the measure is undefined.

Rebalancing. Weights drift between rebalancing dates according to actual returns, then are reset to target weights at the selected frequency, which coincides with the end of the calendar period. The benchmark is not rebalanced.

Conventions. Volatility and risk-adjusted ratios use daily returns annualised with a factor of the square root of 365. The risk-free rate is zero. Correlations instead follow a weekly log convention: the two bases are not comparable with each other.

Survivorship bias. The list only includes assets that exist and are liquid today. Projects that disappeared over past years do not appear, so any result on diversified baskets is by construction more favourable than choosing at the time without knowing the outcome.

Limitations. Transaction costs, fees, spreads, taxes and slippage are excluded: higher rebalancing frequencies are therefore favoured relative to what would have happened in practice. The earliest start date depends on the most recent asset selected. Results derive from historical series and do not indicate future returns.
