Why liquidity, not market cap
A token's price and market cap tell you what it would be worth if every coin could be sold at the last trade. They can't. Liquidity is the money actually sitting in the pool, ready to pay sellers. It's the number that decides what you can get out, so it's the number Waterline charts.
Market cap is a multiplication, not money
Market cap = last price × total supply. The price comes from the most recent trade, often a small one, and the formula applies it to every token, including the billions that have never traded and never could at that price.
Someone buys $500 of a new token
The price doubles in a very thin pool, so a 1-billion-supply token "gains" millions in market cap.
Money that entered the pool
That's all. Nobody can take out the other $1,999,500, because it never existed.
Liquidity is the money that's really there
A pool holds two sides: the token, and the asset it trades against (ETH, WETH or USDG). When you sell, you're paid from that second side. So it's a hard ceiling: all holders together can never pull out more than the cash side of the pool, which is roughly half of its depth. And every sale drains that side, so each seller gets a worse price than the one before.
Two tokens, same market cap, very different reality
Both of these show "$5M market cap" on a price chart. Now try selling $20,000 of each.
You sell $20k
Price drops about 6%. The market cap is only 8× the cash in the pool.
You sell $20k
Price drops about 75%. The market cap is 250× the cash in the pool. The "$5M" was never reachable.
On a price chart these two look identical. On a liquidity chart one is a lake and the other is a puddle.
Why price and market cap are easy to fake
- Thin pools. In a shallow pool a few hundred dollars can double the price, and the market cap with it. Headlines and leaderboards follow.
- Supply games. Market cap counts tokens held by the team, locked wallets and dead addresses as if they were for sale at the last price.
- Wash trading. Buying and selling to yourself paints a rising price and big volume without adding a cent of depth.
- Borrowed names. Copycat tokens reuse famous names and tickers. A price is just a number. Waterline checks stock tokens against the official list and labels fakes.
Liquidity is different. To show deep liquidity you have to lock real money in the pool, where anyone can trade against it. When that money leaves, the chain records it: who pulled, how much and when.
Liquidity moves first
Most rugs are liquidity pulls. On a price chart, a token can look stable until the moment it collapses. On a liquidity chart you can often see the pool thinning, or a single wallet pulling, before the price reacts. The reverse holds too: when providers add money to a pool, they're putting their own capital at risk, which says more than any price candle.
Warning signs worth watching: price going up while depth goes down. A pool whose market cap is dozens of times its depth. One wallet owning most of the liquidity, and that wallet not being locked or burned.

Live numbers from pools Waterline tracks, biggest market cap first. "Cash-out gap" is market cap divided by the cash side of the pool: how many times over the headline number exceeds the money that's actually there.

Estimates use full-range pool math and include a 0.3% pool fee. Concentrated pools can be deeper or thinner near the current price, and routes through several pools can do better. Official stock tokens are left out because their price is anchored to the real share.
How to read Waterline
- The chart is pool depth in dollars. A rising line means more money to trade against. Zoom out, or drag left, to load older history.
- Dots are real liquidity adds and pulls read from the chain, with the wallet behind each one. Bars under the chart show how much depth changed in each period.
- "vs Market cap" overlays market cap on the same chart so you can watch the gap between the headline and the money.
- Reality check on every token shows the most the pool could pay out and what selling 5% of the supply would really fetch.
- Portfolio shows what your holdings would actually sell for, not just their value at the last price.
- Alerts ping you, or the Telegram bot, when liquidity is pulled from a pool you watch.
- Waterline Score rates each token's liquidity from 0 to 100: depth versus market cap, how steady it is, whether it's locked or burned, how spread out the providers are, pool age and contract checks. Projects can embed it as a live badge.
- Top LPs shows the wallets behind the liquidity: how much they add and pull, how long they stay, and whether they tend to pull within a day. Follow one to get an alert whenever it moves.
Rules of thumb
- Liquidity of 10% of market cap or more is healthy for a small token. Under 3% is thin.
- A sale worth 1% of a pool's depth loses about 2% to slippage and leaves the price about 4% lower. Size your trades to the pool, not to the market cap.
- Watch the depth trend, not only the price trend.
What liquidity doesn't tell you
Liquidity isn't a promise. It can be pulled at any time unless it's locked or burned. Concentrated pools can hold most of their money near the current price, or far from it, so the real depth for your trade can differ from these estimates. Stock tokens follow their real share price, and on-chain exits still depend on the pool. None of this is financial advice. It's a better way to see what's actually there.
