Today's crypto prices by market cap
How does a flippening happen?
Rankings feel permanent until they aren't.
A flippening is the moment one coin's market cap passes the coin above it. It can come from a rally, a slide, or both at once, and between coins of similar size it can happen several times in a week.
What counts as a flip
When one coin's market cap passes the one ranked above it, they swap places. It can happen from a rise, a fall, or both.
Today the word is used for any two coins trading places. Flippenings near the top of the rankings get attention because they reflect big shifts in where money is going.
KryptoKap logs flippenings in the top 100 in Milestones, and the Flippening watch shows which pairs are closest to swapping.
Working out the gap
If the coin ranked 8th is worth $20 billion and the 9th is worth $18 billion, the 9th needs to rise about 11% with everything else unchanged. Or the 8th could fall 10%. Or both could move a little.
The Flippening watch tool does this sum for every pair of neighbors and lists the closest.
Why flips get attention
Rank is the simplest way most people see the market, so a coin moving into the top 10 makes headlines and can draw new buyers.
But a rank change between two coins of similar size can be noise. Flips that hold for weeks say more than ones that reverse the next day.
The original flippening, in numbers
With Ethereum at a quarter of Bitcoin's size, a flip needs ETH up 300%, BTC down 75%, or a mix such as ETH doubling while BTC halves.
Ethereum passing Bitcoin is a question of market cap ratio, not price per coin. Comparing one ether's price with one bitcoin's price says nothing, because the two have very different supplies. What matters is Ethereum's market cap as a share of Bitcoin's, a figure KryptoKap shows on this lesson's card.
Take an example where Bitcoin is worth $2.0 trillion and Ethereum $0.5 trillion, so Ethereum is 25% of Bitcoin's size. For a flip, Ethereum could rise 300% while Bitcoin stands still, or Bitcoin could fall 75% while Ethereum stands still. A mix also works. Ethereum doubling while Bitcoin halves would put both at $1.0 trillion. Every path needs the gap of four times to close, however it's split.
Ether's supply isn't fixed, which adds a wrinkle. New ether is issued to stakers and some is burned with transaction fees, so its supply can grow or shrink slightly over a year. Bitcoin's supply grows on a fixed, slowing schedule. Over short periods these supply changes are tiny next to price moves, but over years they shift the ratio a little on their own.
Why close neighbors keep swapping
Two coins near $20 billion swapped places six times in ten days without the gap ever passing 2%. Flips like these are noise until one holds.
When two coins are within a percent or two of each other, ordinary daily moves are enough to swap them. In the example, coin A and coin B sit near $20 billion for ten days. Their caps cross six times, and the gap between them never goes past about 2%. Each crossing is technically a flippening, and none of them means much, because the two coins never really separated.
This is why KryptoKap marks a coin 'Near' the one above when the gap is under 3%, and why it helps to wait before reading anything into a flip. A flip that holds for several weeks, with the gap opening up afterward, says more about where money is going than a dozen swaps back and forth.
Stablecoins add another kind of flip. Their price stays near $1, so they climb the rankings only by growing supply, as people deposit dollars and the issuer creates new coins. Tether rose to third place behind Bitcoin and Ethereum this way. When a stablecoin passes a regular coin, it usually reflects demand for dollars inside crypto, or the other coin falling, rather than any change in price.
Key terms
Flippening
One coin's market cap passing another's.
The Flippening
The original idea of Ethereum passing Bitcoin.
Gap
How much the lower coin must rise to pass the one above.
Milestones
KryptoKap's log of flips and big rank changes.
A rank swap is a size change and nothing more
Which coin is better. A flip compares size on one day. It says nothing about use, safety or where either coin goes next.
Whether it will last. Flips between close neighbors often reverse within days.
Why it happened. A flip caused by the coin above falling is very different from one caused by a real rally.
What people get wrong
A flip doesn't need the passing coin to rise. The other coin falling works too.
Flips near the top can reverse within hours when two coins are close in size.
Why it matters
Rank changes are a simple way to see which coins are gaining ground on their neighbors.
Common questions
How close is close?
KryptoKap marks a coin 'Near' the one above when the gap is under 3%.
Has Ethereum ever flipped Bitcoin?
No. Ethereum came closest in 2017 and 2021, when its market cap reached roughly half of Bitcoin's at times.
Can a stablecoin flip a regular coin?
Yes. A stablecoin's market cap grows when more coins are issued, so it can pass a coin whose price is falling or flat. Tether reached third place in the rankings this way. Those flips reflect demand for dollars in crypto rather than a rally in the stablecoin itself.
Does Bitcoin's price per coin matter for a flippening?
No. One bitcoin costing far more than one ether says nothing about which network is worth more, because they have very different numbers of coins. Flippenings compare market caps, which is price multiplied by circulating supply.
How does KryptoKap record a flip?
When two coins in the top 100 swap ranks by market cap, the change is logged in Milestones with the date. The Flippening watch shows which neighboring pairs are closest to swapping right now and how much each would need to move.
