Is my crypto portfolio too concentrated?
Updated 2026-08-01 · Descriptive analytics, not advice
How concentration is measured
Two weights carry most of the information: the percentage of the portfolio in its single largest position, and the percentage in its top three. A third read, effective independent bets, adjusts the coin count for how closely the holdings move together, which is usually where a portfolio that looks spread out turns out not to be.
Why coin count is misleading
Most altcoins have historically moved with Bitcoin. When holdings rise and fall together, they are one bet wearing several tickers, so a ten coin portfolio can carry the concentration of a two coin one. This is why a concentration read without a correlation read undercounts the risk that actually matters.
The Real Bet Count tracks this for the top coins as a recurring index.
Where to see your own numbers
The free Portfolio Risk X-Ray reports the largest-position weight, the top-three weight and the same-bet correlation read for any portfolio you enter, and folds them into a 0 to 100 structure score with the formula published in full.
Common questions
How many coins make a crypto portfolio diversified?
There is no fixed number, because coin count is not the measured quantity. What the analytics measure is how many genuinely independent bets the weights and correlations add up to. A two coin portfolio of uncorrelated assets can measure as more spread out than a ten coin portfolio of correlated ones.
Is holding mostly Bitcoin bad?
The analytics do not rate a choice as good or bad. They report the weight, the correlation structure and the historical drawdown that follows from it, and leave the judgment to the reader. Every output is descriptive, never a recommendation.
