No margin call in perp futures that I'm aware of. Liquidation is the way There's neither a margin call or liquidation when hodling bitcoins and crypto assets in local wallets
A margin call is the last step before liquidation. If you don't post more margin, then the broker will liquidate your position.
I understand this is a leveraged product. How much do you stand to make or lose per contract. (I'm assuming contracts like index futures) when BTC move $1000.
