Bitcoin is the first and largest cryptocurrency by market capitalization, launched in 2009 as a peer-to-peer digital cash system that operates without a central bank or issuer. It runs on a public blockchain secured by mining, with a fixed supply cap of 21 million coins, and is widely treated as a store of value or "digital gold." BubbleLayer tracks Bitcoin's live price, market cap and volume alongside the rest of the market so you can see at a glance how it's moving relative to altcoins. On a market map Bitcoin is the reference point rather than one bubble among many: its share of total crypto market value — Bitcoin dominance — is watched as a regime signal, because a market where dominance is rising while altcoins fall behaves very differently from one where it is falling. Proof-of-work mining secures the chain, block rewards halve on a fixed schedule, and supply is capped, so issuance is predictable in a way most assets are not. Because it is the largest asset by market cap, BTC usually sits at the centre of a bubble map with the widest circle, and short-term moves in it tend to drag the rest of the board with them.
Why is Bitcoin's bubble always the largest?
Bubble size is drawn from market capitalisation, and Bitcoin has the largest market cap of any cryptocurrency. That says nothing about price per coin or about future performance — it is a measure of total value at current prices.
What does Bitcoin dominance tell you on a market map?
Dominance is Bitcoin's share of total crypto market capitalisation. When it rises, value is concentrating in BTC; when it falls while the map is green, money is rotating into altcoins. The same field of green means different things depending on which way dominance is moving.
Does the halving show up in the data on this page?
Not directly. The halving changes the rate of new supply, not the price or volume figures shown here. Its effect, if any, appears indirectly over long periods in market cap rather than in a single day's numbers.
Is Bitcoin less volatile than smaller coins?
Historically large-cap assets have moved less violently than small-cap ones, but that is a tendency, not a rule, and Bitcoin has had drawdowns of well over half its value. Nothing on this page is investment advice.
Market cap decides how big a bubble is drawn, so rank is what places BTC on the map relative to the rest of its sector.
