There is no single global price tag
An exchange maintains a book of buy and sell orders for a pair such as BTC/EUR. A trade occurs when compatible prices meet. Another exchange, currency or peer-to-peer market has a different set of participants, banking links and rules.
A website showing one rate usually calculates an index or reference price from several venues. That is useful, but it is a methodology. A user's execution also includes the chosen order book, spread, fees and order size.
The latest price is a marginal trade
If a small fraction of BTC trades at EUR 60,000, it does not mean every existing unit changed hands at that price. Only the last matched quantity found a buyer and seller there. The next available order can be higher or lower.
A market order consumes available offers. If it is large relative to depth, it fills at several prices and suffers slippage. A limit order protects a price boundary but may not execute.
Liquidity dampens movement; it does not abolish it
A liquid market can absorb a larger order with less slippage. Volume measures traded activity, while depth measures available quantity near the price; high reported volume does not automatically mean a deep or honest market.
An arbitrageur can buy where bitcoin is cheaper and sell where it is dearer. Research has nevertheless documented persistent gaps across crypto markets because capital transfers, fees, withdrawal limits and counterparty risk matter.
- spread separates the best bid and ask
- depth counts quantity near the price
- arbitrage carries costs and risk
What can move demand
Payment access, regulation, macroeconomic uncertainty, a technical failure, media attention and expectations about other users can all change demand. The same news can encourage one participant to buy and another to sell. No single indicator captures every motive beforehand.
The issuance schedule is only one side of the market. Short-run price also depends on how much is available now and the venue's liquidity. A one-sentence explanation for a move is often a story rather than an established cause.
