Fear & Greed Index
Today's crypto Fear & Greed reading on a gauge, with yesterday's and last week's for comparison. Readings come from alternative.me and refresh a few times a day.
Altcoin Season Index
KryptoKap's own measure of whether altcoins or Bitcoin are leading: the share of the top 100 coins that beat Bitcoin over 90 days. Near 100 is altcoin season, near 0 is Bitcoin season.
KryptoKap Pulse
A 0 to 100 reading of the market's mood worked out from prices alone, so it moves with the market rather than with surveys or social media.
Bitcoin dominance
Bitcoin's share of the whole crypto market, its change over the last week and a 90-day line. A rising share usually means money is favouring Bitcoin over other coins.
Spot Bitcoin ETF flows
Net money into or out of spot Bitcoin funds for the last 20 trading days, with the latest day up top. Built from the funds' own share counts.
Bitcoin halving countdown
Blocks left until the next halving, how far through the current era Bitcoin is, and the expected month, based on how fast blocks have been arriving.
Fear & Greed as an image
Some places don't allow embedded frames: forums, GitHub READMEs, many newsletter tools. This version is a plain image that redraws whenever the index changes, so it works anywhere an image does.
Questions
Do the widgets cost anything?
No. They're free for personal and commercial sites, with no account or key. Please keep the small KryptoKap credit and the link under the widget.
Will they slow down my page?
Each one is a few kilobytes and loads lazily, so it only loads when a reader scrolls near it. Nothing runs on your page itself; the widget lives in its own frame.
Do they track my visitors?
No. The widgets set no cookies and run no tracking scripts. KryptoKap counts page views on its own site without cookies, and doesn't count widget views at all.
How often do the numbers change?
Prices refresh every hour, the halving countdown every 30 minutes, ETF flows once a day after funds report, and Fear & Greed when alternative.me publishes a new reading.
Can I change the size?
The cards are built for 320 pixels wide and shrink to fit narrower spaces. Changing the height in the code will crop the card, so keep the height as given.
