Theoretically, yes. In practice, it depends on your tolerance. If the decline is too large and there is no stop loss in time, you will not explode, but you will be bound by the delivery date, which is determined by the nature of the futures contract. But the extended contract completely meets your problem. You can hold it indefinitely without delivery. In theory, you can guarantee that you won't explode your position and have enough margin. Trading time for space will rise back to your cost sooner or later.
