Just been looking at the ETH rainbow chart again and it's wild how useful this thing is for understanding where Ethereum sits in its long-term cycle. So basically this tool maps ETH's price on a logarithmic scale against these colored bands that represent different valuation zones over time.

Right now ETH is trading around $2.31K, and according to the rainbow chart model, we're sitting in what they call the 'Still Cheap' band - roughly between $2,577 and $3,652. What's interesting is that even though we're in this zone, it suggests Ethereum is still reasonably priced relative to its long-term growth trajectory, just not at those deep discount levels anymore.

The chart basically works like this: at the bottom you've got 'Fire Sale' territory (extreme pessimism, $994-$1,340), then 'Undervalued' ($1,340-$1,843), then 'Accumulate' where smart money historically builds positions ($1,843-$2,577). Above where we are now is 'Steady' ($3,652-$5,252), which is supposed to represent balanced conditions. Keep going up and you hit 'HODL' territory, 'Is This the Flippening', and eventually 'Maximum Bubble Territory' at the top.

The way this ETH rainbow chart works is it doesn't predict exact prices - it's more about showing you where price sits relative to the historical trend and adoption cycles. Pretty useful mental model for understanding if we're in euphoria or if there's still room to run. The bands adjust over time as the long-term curve expands, so it's dynamic rather than static levels.
