You are right, the farther the liquidation price is, the less likely they will take you out. For that to happen, your futures account must be at zero. This can be avoided by adding more money.

This strategy is the best, place 1$ at 75x, then if it approaches your liquidity price, add another 1$ , and so on! Place new orders at an entry price closer to your liquidity price, and this way your liquidity price moves away from your entry price. Trust me, you will only lose if you run out of money.
