Show that crypto prices differ across exchanges at the same moment, unlike forex's interbank quote model.
There is no single 'Bitcoin price'
Pull up Bitcoin on three different exchanges right now. Coinbase, Binance, Kraken. The prices will be close — within a few dollars usually — but they will not be identical. One might show 67,420. Another 67,398. The third 67,445. All at the same instant. This isn't a glitch. This is just how crypto works. Every exchange runs its own order book. Buyers and sellers on Coinbase only trade against other people on Coinbase. They never meet the buyers and sellers on Binance. So each venue discovers its own price.
Forex doesn't work this way. In forex, banks quote each other through a system called the interbank market. Prime brokers, ECNs, and aggregators pull those quotes together so that the price you see at Broker A is essentially the same price you see at Broker B. There might be a tiny spread difference, but EUR/USD at 1.0850 on one screen is 1.0850 on every other screen too. That's because forex has a single underlying global pool of liquidity. Crypto doesn't.
Why do prices diverge? A few reasons. Each exchange serves a different user base — US retail dominates Coinbase, global retail dominates Binance, pro and institutional traders cluster on Kraken and OKX. Different demand profiles produce different prices. Fees and withdrawal frictions also matter: if it costs $30 and 20 minutes to move Bitcoin from Binance to Coinbase, prices on those two venues can drift apart by more than the cost of arbitrage before anyone bothers to close the gap. Plus regional regulation creates real walls — Korean exchanges historically traded at a premium called the 'kimchi premium' because capital couldn't easily leave Korea to arbitrage it away.
Practical takeaway: when you take a trade on a crypto chart, your entry, stop, and target are all venue-specific. The price action you're reading is the price action on YOUR exchange's order book. Don't quote a price from one venue and try to execute on another — they're literally different markets that share a ticker symbol.
Recap: every crypto exchange is its own marketplace with its own price. Forex prices converge because of the interbank market. Crypto prices diverge because there isn't one. Pick a venue, stick with it, and read its chart.
