How Can a Miner Manage the Cash Flow Risk Associated with Margin Calls?

A miner can manage cash flow risk by maintaining a high level of excess collateral above the initial margin requirement. They can also set aside a dedicated fiat reserve to cover potential margin calls, treating it as an insurance cost.

Alternatively, they can use put options instead of futures for hedging, as options require only an upfront premium and have no margin call risk, limiting their maximum loss.
