There is no single 'Bitcoin price' — there are dozens of venues arbitraged into one number within milliseconds. Spot exchanges trade actual coins; perpetual futures (perps) trade leveraged exposure and carry a funding rate that tugs them toward spot. Most short-term violence originates on perps, where leverage lives, then arbitrage drags spot along.
What this means for reading BTC
- Funding rate = crowd positioning. Heavily positive funding (longs paying shorts) means the boat is loaded long — fuel for downside cascades.
- Wicks that seem senseless are usually liquidation events on leveraged venues rippling through arbitrage (next lesson).
- Thin books amplify everything: the same size order moves BTC 3× further at 4am Sunday than mid-US-session Tuesday.
You don't need to trade perps to be moved by them. When a move feels 'impossible', ask what the leveraged crowd was forced to do — forced flow explains most of crypto's weirdness.
