Spot trading

When you buy BTC on the spot market, you actually own Bitcoin. You can withdraw it to your wallet. The price you pay is the real, immediate market price. There is no leverage unless you borrow specifically to trade.

Spot is simple. Buy, hold, sell. No funding rates, no liquidations, no expiry.

Perpetual futures

Perpetual futures are contracts that track the price of BTC (or ETH, SOL, etc.) without you ever owning the underlying asset. You are essentially making a bet on whether the price will go up or down.

Key differences from spot:

• You can use leverage — trade more than your account balance
• You pay or receive a funding rate every 8 hours
• Your position can be liquidated if the market moves against you
• There is no expiry date — you can hold indefinitely (paying funding)
• You never actually own the cryptocurrency

Why futures data is so useful

Because futures involve leverage and funding costs, they reveal conviction. A trader opening a large leveraged long is making a strong directional bet with real cost attached — they pay funding and risk liquidation. This makes futures positioning data more informative than spot activity alone.

When you see on Deriflux that funding is elevated and 65% of Binance futures traders are long, you are seeing leveraged bets — not just people holding BTC in their wallets. That is more meaningful as a sentiment indicator.

Which market leads price?

Generally, the futures market reacts faster than spot. Large institutional players and algorithmic traders operate primarily in futures. Significant moves often show up in futures open interest and funding before they appear clearly in the spot price chart.

This is why monitoring derivatives data gives you context that pure price charts cannot.
