Crypto Market Basics
Understand the numbers that actually matter before you trade
What Makes Up the Crypto Market
Before you trade, you need to understand the language of the market. Every coin has a price, but price alone tells you almost nothing. What matters is the full picture — market cap, supply, and trading volume.
These three numbers tell you how big, how liquid, and how trusted an asset is.
Market Cap — The Size of an Asset
Market Cap = Price × Circulating Supply
A coin priced at $1 with 1 billion coins has a market cap of $1 billion. A coin at $50,000 with 19.8 million coins has a cap of $990 billion.
Market cap tells you the true size of an asset — not just its price. This is why comparing prices directly is misleading. A $1 coin is not "cheaper" than a $50,000 coin unless you look at the full market cap.
Supply — How Many Coins Exist
Circulating Supply — coins currently in circulation and tradeable.
Total Supply — all coins that exist, including locked ones.
Max Supply — the hard cap; no more coins can ever be created. Bitcoin has a max supply of 21 million — this is why it is called "digital gold".
Ethereum has no max supply, but its issuance rate is very low after the merge. Supply dynamics directly affect price over time.
Volume — How Active the Market Is
24h Volume is the total value of all trades made in the last 24 hours.
High volume means the market is liquid — you can buy and sell easily without moving the price. Low volume means the market is thin — a single large trade can swing the price significantly.
Always check volume when entering a trade. A breakout on low volume is often a false signal.
BTC Dominance — The Market Mood Indicator
BTC Dominance is Bitcoin's share of the total crypto market cap.
When dominance is high (55%+), capital is concentrated in Bitcoin — the market is cautious and risk-averse. When dominance falls, capital flows into altcoins — this is called "altseason".
Watching BTC dominance helps you understand whether the market is in risk-on or risk-off mode.
A coin costs $0.001 but has 1 trillion tokens in circulation. Its market cap is $1 billion. Another coin costs $10,000 but has only 50,000 coins — market cap $500 million. Which is the larger asset?
- The $0.001 coin — its market cap is $1 billion
- The $10,000 coin — its price is higher
- They are the same size
