The strategy is wrong. Knowing it will break 100,000, why stay in cash? Can you usually be so certain whether it will rise or fall? This is what retail investors do; they know it will either break 100,000 or drop below 90,000, and they wait, waiting for the spike to reach the target point, thinking that a breakout or breakdown will lead to certain outcomes. Trading should be done at points like this, not by staying in cash. If you're afraid of a spike, then just buy the spot price at 99,800 and sell at 100,000. It's better to secure a few certain points than to gamble with contracts.
