Including whether they are really different bets
Pick two coins and this page puts their returns next to each other over 30 days, 90 days, one year and two years, alongside volatility, beta to Bitcoin, how far each sits below its all-time high, the worst drawdown in its history, and what each did on the days Bitcoin fell hard. Everything is computed in your browser from Binance daily closes.
Several windows are shown rather than one because the window usually decides the winner. A comparison that leads with a single return figure has quietly made a choice on your behalf, and if the lead changes between one month and two years then the headline was a choice of period rather than a property of the asset. Where that happens, the page says so.
The number most comparisons omit is the correlation between the two. When it sits above roughly 0.7 — as it does for most large-cap crypto pairs — the coins mostly differ in how much they move rather than in when, so picking between them is closer to choosing exposure than to choosing a different bet, and owning both is not diversification. That figure decides whether the rest of the table is answering an interesting question at all.
⚠️ Not investment advice. Every figure here describes the past, and coins with shorter histories are being judged on shorter and often easier samples. All decisions and risks are your own.
The comparison has no fixed answer because it depends entirely on the window. This page shows returns over 30 days, 90 days, one year and two years precisely so you can see the lead change, and it says so when it does. A single headline figure is a choice of period presented as a property of the asset.
Because it decides whether the comparison is interesting. Most large-cap crypto pairs correlate above 0.7, which means they differ mainly in how much they move rather than in when. Choosing between them is then closer to choosing exposure than to choosing a different bet, and holding both is not diversification.
It measures how much the coin has tended to move for a given Bitcoin move. A beta of 1.5 implies roughly one and a half times the move in either direction. Since almost all crypto moves with Bitcoin, beta is often more informative about a coin than its own return figures.
Because drawdown is what determines whether a position is holdable. Two coins with the same annual return are not equivalent if one of them fell eighty percent along the way. The table also separates the worst drawdown ever from the current distance below the high, which are different questions.
Not entirely, and the page notes the overlapping history it used. A coin listed recently is judged on a shorter and usually easier sample, since it has not lived through as many market regimes. The day counts beside each coin are there so that asymmetry is visible.
There is no evidence here for that, and this page makes no such claim. Volatility and correlation persist to a useful degree, drawdowns describe what holders have already endured, but the return column describes a period that has already happened.
