Going short means establishing or increasing a sold exposure, commonly to benefit from a price decline or hedge an existing holding. Simply selling coins already owned can reduce a long without creating a short.
Choose the mechanism
A borrowed-asset short involves borrowing an asset, selling it, and later obtaining that asset to repay the loan. Borrowing availability, interest and repayment terms matter. Selling a futures or perpetual contract instead opens contractual exposure when the account’s position mode and order instructions permit it.
A sell order may first reduce an existing long in a netting system. Its unfilled quantity does not yet create short exposure, although orders can reserve collateral and borrowing may occur before execution under some systems.
Know the exit and obligations
Closing a derivative short generally requires a corresponding buy, with the correct close or reduce instruction. A borrowed-asset short also requires settling the loan and accrued charges; buying the asset back does not always trigger repayment automatically.
Price rises can generate large losses and liquidation. Funding, liquidity and collateral changes can alter the outcome even if the market eventually falls. Shorting is therefore an exposure choice, not a guaranteed way to profit from a bearish forecast.
