Spot Trading: Direct Ownership
In spot trading, you buy an asset with cash and receive the asset itself. You own BTC, ETH, or SOL. Your downside is limited to 100% of what you spent — the asset can go to zero, but you cannot lose more than you put in. Your upside is unlimited. There is no funding cost, no liquidation risk, and no position that can be forcibly closed by an exchange.
Spot trading is appropriate for long-term positioning — buying and holding an asset over months or years based on a fundamental thesis. It is the appropriate mode for the "I believe in Bitcoin's future" investor. It is less appropriate for systematic short-term signal trading, because spot does not allow SHORT positions (profiting from price decline) and does not allow leverage.
Perpetual Contracts: Directional Exposure
Perpetual contracts give you exposure to an asset's price movement without owning the asset. You can go LONG or SHORT. You can use leverage to control a larger position with less capital. You pay a funding rate to maintain the position over time. And you face liquidation risk if your margin is insufficient to cover an adverse price move.
Perpetuals are the instrument of choice for systematic signal trading because they enable both directions, enable leverage for capital efficiency, and can be sized precisely using the invalidation-based formula.
