How does the KryptoKap 10 index work?
Ask "how is crypto doing today?" and most people check Bitcoin.
An index gives a better answer by tracking the ten largest coins as one number. But because bigger coins count for more, Bitcoin still does most of the talking, and seeing exactly how much is the point of this lesson.
How the KryptoKap 10 works
In a cap-weighted index, bigger coins count for more. With Bitcoin at about two-thirds of the weight, it sets the direction on most days. Free to reuse
It started at 1,000. Bigger coins count for more, so Bitcoin moves the index far more than the tenth-largest coin does.
Stablecoins and gold-backed tokens are left out. When a coin enters or leaves the top ten, the index rebalances without jumping, the same way stock indexes handle changes.
A worked example
If Bitcoin makes up 70% of the index's value and rises 2% while the other nine are flat, the index rises about 1.4%. If the other nine all rise 5% and Bitcoin is flat, the index rises only about 1.5%.
That's cap weighting in practice, because the biggest coin sets the direction most days.
What an index is good for
Comparing yourself with it is the main use. If your portfolio rose 8% in a month when the KryptoKap 10 rose 12%, you trailed the core of the market, even though you made money.
It also smooths out single-coin noise, so you can see whether a move is market-wide or limited to one coin.
How a rebalance avoids a jump
Swapping a $40 billion coin for a $50 billion one adds $10 billion to the total. Resetting the divisor keeps the index at 1,000, so only price moves change it. Free to reuse
Cap-weighted indexes don't simply add up market caps and print the total. They divide the combined market cap of their members by a number called the divisor, which is set so the index equals its base value on day one. After that, price moves change the total and the index moves with them.
The divisor earns its keep when membership changes. Say the ten members are worth $2.00 trillion combined and the index reads 1,000, so the divisor is 2 billion. The tenth coin, worth $40 billion, drops out and a new one worth $50 billion takes its place. The new total is $2.01 trillion. Divided by the old divisor, the index would leap to 1,005 even though no price moved. So the divisor is reset to 2.01 billion and the index stays at 1,000.
Stock indexes such as the S&P 500 use the same method for additions, deletions and share changes. The practical point is that a jump in the index always reflects price moves of its members, never a swap of who is in it. If a coin you follow joins the top ten, that alone won't show up as a spike.
When the index and most coins disagree
With Bitcoin at 60% of the weight, its 5% gain outweighs eight smaller coins each falling 3%. The index rises 2.4% while the typical member falls. Free to reuse
Because weights follow market cap, the index can go one way while most members go the other. Take an example day where Bitcoin is 60% of the index and rises 5%, the second coin is 12% and rises 2%, and the other eight, together 28%, each fall 3%. Bitcoin adds 3.0 points of percentage, the second coin adds 0.24, and the eight fallers subtract 0.84. The index finishes up about 2.4%.
Now average the ten moves with equal weight. One gain of 5%, one of 2% and eight losses of 3% give a simple average of minus 1.7%. Eight of the ten members fell, yet the headline number rose.
You can check this yourself on any big day. Open the index on KryptoKap, then look at the daily change of each member on the coins list and count how many are green. If the index is up but most members are red, the move is narrow and rests on the largest coin. Comparing the index with Bitcoin dominance tells the same story from another angle.
Key terms
Index
One number that tracks a group of assets.
Cap-weighted
Each member counts in proportion to its market cap.
Rebalance
Updating members and weights without the index jumping.
Base value
The starting level, 1,000 for the KryptoKap 10.
Ten coins, one number, and a lot left out
How the typical coin did. Cap weighting means the index can rise while most of its members fall.
Anything outside the top ten. Small and mid-sized coins can have a great week without moving the index at all.
What you could earn. It's a measurement, not a fund, so there are no fees, rebalancing costs or slippage in it.
What people get wrong
The index isn't an investable fund. It's a measurement.
Cap weighting means the index is dominated by Bitcoin. It can rise while most of its members fall.
Why it matters
One number for the market's core makes it easy to compare any coin, or your portfolio, against the big picture.
Common questions
How does cap weighting work?
Each coin counts in proportion to its market cap, so larger coins have more influence.
Why does the index leave out stablecoins?
They're designed to stay at $1, so including them would make the index move less without saying anything about the market.
Can I invest in the KryptoKap 10?
No. It's a measurement, not a product, so there's nothing to buy. Some funds and exchange-traded products track other crypto indexes, but they charge fees and may differ in rules and membership. Comparing your portfolio with the index costs nothing and needs no account.
How often does the KryptoKap 10 change members?
Membership follows the ten largest eligible coins by market cap, so it changes when a coin's market cap passes one of the current members. The divisor is adjusted at that moment so the index level doesn't jump.
Why compare my portfolio with an index instead of with Bitcoin?
Bitcoin is one coin, so beating or trailing it says more about that coin than about the market. The index covers the ten largest coins, weighted by size, which makes it a fairer yardstick for a portfolio that holds several large coins. If you hold only Bitcoin, comparing with Bitcoin itself makes more sense.
