Great question. Yes, we will always have enough bitcoins to pay any profits! However, like most other futures exchanges, we do have an auto-deleverage system. This means that, if you open a 100x long position and price rises too much too fast, causing short positions to be liquidated, and if there is not enough liquidity on the book to close short positions, long positions with highest leverage may be forced to close their positions.

During auto-deleverage, our positions are always closed at a price between the bid/ask. Some other exchanges have badly designed auto-deleverage mechanisms that close positions are a price unrelated to the current orderbook -- this is sometimes called a 'clawback'. We don't do anything like that.

So positions will be usually closed at fair prices (or even better than usual prices if the liquidating positions caused some slippage). If prices move suddenly, though, or if prices move during an exchange outage, highly-leveraged positions may see smaller profits than what one might expect.

For example if you buy bitcoin with high-leverage at $35,000, current price is $36,000 and price start going up really fast and there is no liquidity to liquidate short position, at some point (maybe if it hits $40,000) you may see your position closed automatically at a profit. It price keeps rising after that, you may be disappointed later that your position was closed. But if the prices falls back after that, so you may even be glad we closed your position for you!

Even so, we'll have an insurance fund in the future to prevent auto-deleverage events from happening.
