Crypto Market Structure
If there is no closing bell and no single exchange, what is the price?
The idea
Crypto trades continuously across fragmented venues, each with its own prices, liquidity, custody, and rules.
In the real world
BTC can trade at slightly different prices on two exchanges until arbitrage closes the gap.
Going deeper
There is no single venue and no closing auction, so there is no single price — only many local prices on venues with their own books, users and rules. Quoted figures on trackers are weighted averages of places you may not be able to trade.
Gaps persist because closing them costs money. Arbitrage needs capital positioned on both sides, and pays transfer times, withdrawal limits and fees. When those costs exceed the spread, the gap simply stays open, which is why apparent free money on a screen is usually already priced by frictions you are not seeing.
Where it stops applying
For the largest assets on major venues, prices track each other closely enough that this rarely matters to a retail-sized order. It bites on smaller tokens and thinner venues.
Why it matters
It explains why the number you see quoted is an average of many venues, none of which you can necessarily trade at.

Before trading, identify the venue, counterparty, custody model, and settlement risk.
Test yourself
A tracker shows one price. Two exchanges show prices 0.8% apart, and the gap persists for an hour. Why does this happen, and why does it not close instantly?
Show the answer
Each venue has its own book, liquidity and users, so prices are local. Closing the gap requires capital on both sides, plus transfer time, fees and withdrawal limits, and when those costs exceed the spread the gap simply stays open.
