How to read a crypto index methodology in 10 minutes

Open any crypto index's methodology page and you are ten minutes from knowing how the product works. Five checks do it, at roughly two minutes each.

Five frosted glass panels in a row, one glowing orange with a checkmark, beside the text "Five checks. Ten minutes." and "Read the rule, not the return."

The point

Open any crypto index's methodology page and you are ten minutes from knowing how the product works. Five checks do it, at roughly two minutes each. Three of them cover what gets into the basket, what stops one holding from swallowing the rest, and when the rebalance fires. The last two are what a year of it costs, and whether the provider can rewrite the rules without telling you.

The chart is the wrong thing to read first

A return chart is the easiest thing to find on an index's page. Search for a crypto index and most results lead with a chart or a ranking. A chart records what already happened, which is the part you cannot act on.

The methodology is where the automatic behaviour is written down. It says what the basket does the next time the market moves in a way nobody saw coming. That is the moment a person deciding by feel tends to freeze.

Every serious crypto index, including ours, publishes those rules somewhere public.

The five checks, about ten minutes total

Check 1: what is allowed in?

A methodology should say what an asset has to clear before it is even considered. Look for numbers: a liquidity floor, a market-structure standard, and how long a track record has to run.

The S&P 500's own constituents are chosen by a committee against published criteria. Named criteria, applied by a defined process, is the standard worth holding any index to.

If the page says "quality assets" or "leading cryptocurrencies" and stops there, nothing has been specified. QSI Core's own page names its four holdings and the job each one does.

Check 2: the ceiling on a single holding

Most crypto indices weight by market value, so the biggest asset gets the biggest slice by default. That default has a name, cap-weighting, and it is a defensible starting rule. What matters is the limit sitting on top of it: a stated ceiling one holding cannot cross, even if it doubles overnight.

QSI GEQ8 publishes exactly that number: no single holding above 15 percent or below 3 percent, enforced at every rebalance. If your page carries no equivalent number, ask what happens to the basket the month one coin runs away with the market. Usually the answer is nothing, and that gap is your finding.

Check 3: what triggers the rebalance

A methodology should name a rebalancing cadence, the schedule on which the basket is reset, and say plainly what sets it off. Two designs actually name the trigger, calendar and threshold. A calendar rule fires on a fixed date, whatever the market did that week. A threshold rule fires when a holding drifts past a stated band, a set distance from its target weight.

Both work. A page that says "rebalanced periodically" and leaves the trigger to somebody's discretion has named neither.

QSI Growth rebalances monthly, on the calendar. A defined set of events can also trigger an off-cycle review: a security failure in a holding, or a structural break in liquidity. Ask whether you can name the date or the drift number that moves the basket, without asking anyone.

Check 4: the annual cost you can work out yourself

Three numbers decide this: the fee charged per transaction, any annual management fee, and how many times the basket rebalances in a year. With all three on the page, you can work out the yearly cost on paper before you invest a rupee. With one of them missing, or with the fee section saying "competitive" where a rate should be, the cost cannot be worked out at all.

Across all four QSI indices the basket fee is 0.35 percent per rebalance, and there is no annual management fee. That settles two of the three numbers. Check 3 supplies the cadence.

Check 5: who can change the rules?

A methodology is a document, and documents get revised. A revision that is versioned and dated leaves the earlier version readable six months later. One that is not leaves you comparing today's page against your memory.

Our own methodology is written down, versioned and dated, and the previous version survives an update. Where a page cannot say who approves a change and where the history lives, the rule is a promise, and you have no way to check that it held.

Over a multi-year hold, check 5 costs you more than the other four when it goes unanswered, and most checklists leave it out.

Running the checklist on our own four

Running all five checks against one provider takes about the ten minutes the title promises. QSI VRION's page is the quickest of our four, because its construction is the simplest: three assets, no buffer, a stated five-year minimum horizon. Checks 1 and 2 resolve in seconds there, which leaves check 5 worth your remaining minutes. The same pattern holds on whichever provider's page you have open.

Run it yourself and you are trusting something you checked. A deeper five-point framework goes further than ten minutes on a single product. Ten minutes is enough to decide whether a page deserves that.

What ten minutes will not tell you

The checklist says nothing about whether an index will perform well. Methodology and performance are separate questions, and a well documented rule can still sit inside a bad year for the whole asset class.

It also will not catch a provider who lies on the page. A fraudulent methodology can read cleanly while a different process runs behind it.

What it does catch is the ordinary case: a page that never says enough to be checked, read by somebody who was looking at the chart.

Frequently asked questions

How long does it take to check a crypto index's methodology?

About ten minutes for the five checks above, assuming the methodology page is public and reasonably complete. A vaguer page reads faster, because there is less written down to check.

What is the single biggest red flag in a crypto index's methodology page?

A stated rule with no number behind it: "quality assets," "competitive fees," "rebalanced periodically." Each is a placeholder where a criterion should be. A placeholder cannot be checked against anything real.

Does a hard cap on one holding's weight actually matter?

Yes. A cap decides what happens the month one asset runs far ahead of the rest. Without one, a basket can end up concentrated in whichever asset had the best year. That defeats the point of holding a basket at all.

Why does it matter whether a methodology change is versioned?

Because an unversioned methodology can be redefined quietly and still carry the same product name. A versioned, dated one lets you read today's rule against the rule you signed up to.

Can I run this checklist on Qatobit's own QSI indices?

Yes. All four, QSI Core, QSI Growth, QSI VRION and QSI GEQ8, publish the kind of methodology page this checklist is built to test. Run it on them the way you would on anyone else's.
