A Beginner's Guide to Dominance
Dominance tracks which assets own the biggest slice of the market. Here's what it means, why traders watch it, and how to trade BTCDOM, ETHDOM, and more.
What is dominance?
Imagine you’re at a birthday party and there are eight pizzas on the table. Four of those pizzas are pepperoni, two are cheese, one is veggie, and one is BBQ chicken. Pepperoni doesn’t just exist at that party. It dominates it. Half the pizza is pepperoni. If someone takes two slices of cheese and the pepperoni supply stays the same, pepperoni’s share of the table just got bigger. That’s dominance: how much of the total pie one thing takes up.
Markets work the same way. Every industry has players, and those players each hold a slice of the total value. When analysts talk about one company “gaining market share,” they mean its slice is growing relative to everyone else’s, even if the whole pie is also getting bigger. Dominance is just that ratio, expressed as a percentage.
What is crypto market cap dominance?
First, market cap: it’s simply price multiplied by the number of coins in circulation. If a coin costs $10 and there are 100 of them in existence, the market cap is $1,000. Easy.
Crypto dominance takes that number and asks: what percentage of the total crypto market does this one coin represent? The formula in plain English is: take one coin’s market cap, divide it by the combined market cap of all crypto, and multiply by 100.
Here’s a quick example with round numbers. Imagine the total crypto market is worth $1,000. Bitcoin’s market cap is $600. That makes Bitcoin’s dominance 60%. Simple as that. If Bitcoin’s market cap stays at $600 but a bunch of altcoins launch and push the total market to $2,000, Bitcoin’s dominance drops to 30% even though the price of Bitcoin didn’t move at all. That’s the magic (and the mischief) of dominance as a metric: it captures relative strength, not just absolute price.
On domination.finance, you can trade five live dominance pairs in real time:
- BTCDOM (Bitcoin Dominance): Bitcoin’s share of the total crypto market. BTCDOM going up means Bitcoin is growing faster than the rest of the market, or the rest of the market is shrinking faster than Bitcoin.
- ETHDOM (Ethereum Dominance): Ethereum’s share of the total crypto market. Rising ETHDOM often signals that capital is flowing into Ethereum and its ecosystem relative to the broader market.
- USDTDOM (Tether Dominance): Tether’s share of the total crypto market. This one behaves differently from the others. When traders get nervous and park their money in stablecoins, Tether’s share of the total market grows. So USDTDOM rising is often a fear signal; falling USDTDOM can mean money is flowing back out into riskier assets.
- BNBDOM (BNB Dominance): BNB’s share of the total crypto market. Rises when the BNB ecosystem is outperforming and pulling capital from the broader market.
- SOLDOM (Solana Dominance): Solana’s share of the total crypto market. Reflects Solana’s relative strength, which can spike during periods of heavy ecosystem activity or narrative momentum.

Why should you trade dominance?
Think of trading outright crypto prices like betting on who wins a race. But trading dominance is more like betting on who finishes first relative to everyone else, even if the whole pack slows down. That distinction matters more than it sounds.
Because dominance is a ratio, you don’t need to predict whether the overall market goes up or down. You just need a view on relative performance. If you think Bitcoin will hold its ground while altcoins sell off, BTCDOM going up is your trade, regardless of where BTC’s price in dollars is heading. That’s a genuinely different kind of bet.
Dominance also lets you express views on narratives. “Alt season” (the idea that smaller coins will outperform Bitcoin) shows up as falling BTCDOM and rising ETHDOM or SOLDOM. “Flight to safety” within crypto, when people reduce risk, shows up as rising USDTDOM. You can take a position on the story, not just the price.
There’s a hedging angle too. Say you hold a bunch of altcoins and you’re worried they might underperform Bitcoin in the near term. Going long BTCDOM can offset some of that pain without forcing you to sell your alts. It’s a way to stay in the game while managing the relative exposure.
And because dominance doesn’t move in lockstep with raw prices, it can behave differently from everything else in your portfolio. That lower correlation is genuinely useful when you’re trying to diversify across positions.
When should I trade dominance?
Different pairs light up in different conditions. Here’s a simple way to think about when each pair becomes interesting:
- BTCDOM tends to be most actionable around risk-off macro events, Bitcoin ETF news, halvings, or any moment where you expect capital to either pile into Bitcoin as a safe haven within crypto or rotate out of it into riskier assets.
- ETHDOM becomes interesting around major Ethereum catalysts: protocol upgrades, ETF flow developments, or periods when Ethereum’s layer-2 ecosystem is attracting serious attention and capital.
- USDTDOM is your fear gauge. Expect it to rise when something spooks the market and traders park cash in stablecoins. Expect it to fall when confidence returns and money flows back into coins.
- BNBDOM and SOLDOM are ecosystem plays. If you have a strong view that the BNB or Solana ecosystem is about to outperform or underperform the broader market, based on network activity, developer momentum, or major app launches, these are the pairs that capture that view directly.
For beginners, a few signals are worth keeping an eye on. Sharp drops in BTCDOM have historically preceded periods when altcoins broadly outperform, so it can serve as an early-warning indicator. Sustained rises in USDTDOM suggest the market is de-risking and caution may be warranted. And when SOLDOM or ETHDOM quietly trends up over several weeks, it often reflects genuine ecosystem momentum that outright price action doesn’t always capture as cleanly. The docs go deeper on how to read these signals across each pair.
