How Closely Do Altcoins Really Follow Bitcoin?
Closely, and the correlation is highest exactly when you would most want it to be low.
Bitcoin right now, in numbers
Bitcoin is $80,024 right now, down 0.41% in 24 hours and down 2.23% over 7 days. The last week ranged from $79,548 to $80,449; market cap $1.61T, ranked #1.
The all-time high is $126,080 (Oct 2025), 36.5% below today's price.
On a typical day BTC moves 1.19%; one day in ten moves more than 3.53%, and the largest single day in the last 365 was 14.02%. A 5% alert would have fired about 1.4× a month — rare enough to still be worth reading.
| 24h move | Fired per month | Per year |
|---|---|---|
| 2% | 8.1 | 98 |
| 3% | 3.7 | 45 |
| 5% | 1.4 | 17 |
| 8% | 0.2 | 2 |
| 10% | 0.2 | 2 |

The pattern
In calm conditions, alternative assets show meaningful independence — asset-specific news and ecosystem developments drive relative performance, and a portfolio of several looks genuinely diversified.
During sharp moves, particularly downward, correlations converge toward one. Almost everything falls together regardless of individual merit, because the same participants are selling everything to raise cash and the same liquidity conditions apply across the board.
Why smaller assets amplify rather than diverge
Smaller assets typically move further than Bitcoin in both directions. Thinner liquidity means the same flow moves price more, and their holder base is more speculative and quicker to exit. The result is that they fall harder in a decline and rise harder in a rally.
That is amplification, not diversification. A portfolio of ten small-caps is, in a drawdown, effectively a leveraged Bitcoin position — which is a legitimate thing to hold, but it should be held knowingly and sized accordingly.
What actually reduces correlation
Within crypto, very little does reliably. The assets with the most independent behaviour tend to be those with distinct holder bases or distinct drivers, and even those converge under stress.
Genuine decorrelation comes from outside the asset class — equities, metals, cash, each responding to different forces. That is the practical argument for tracking across markets in one place: it is the only way to see whether your portfolio is actually diversified or merely numerous.
The same thinking applied outside crypto
Treating crypto as a separate universe from your other holdings is a mistake of framing. Levels, position sizing, deciding in advance and being notified rather than watching apply identically to equities, metals and currencies. The parameters change — a 1% move in a major currency pair is a significant event where a 1% crypto move is background noise — but the method does not.
Watching them together also reveals relationships that are invisible one market at a time. The dollar's strength sets the backdrop for every risk asset. Gold and Bitcoin are both pitched as hedges against currency debasement, and their divergences say something about which story the market is currently believing. When large-cap tech sells off hard, crypto rarely rallies for long.
That is the argument for one watchlist rather than four apps: a portfolio is a single thing, and the correlations between its parts are usually more important than any individual holding.

Frequently asked questions
What is a sensible alert threshold?
Wide enough that firing is unusual. Compare the threshold to the asset's typical daily range over the past month: if the alert sits inside that range it will fire constantly and you will stop reading it. For most large-cap crypto, 5–10% is a reasonable starting point; high-volatility assets need considerably more, and currencies need far less.
Set an alert for this: crypto price alerts, or every market and alert type. Choosing an app? How the alert apps compare, from their own pricing pages.
