Back then, when I was a qualified Air Force commander, I shorted WIF from 0.18 and kept adding to my position up to $4.3, with a total holding of 150,000 coins. In the end, I couldn't hold on anymore and exited with tears, incurring a loss. When I closed the position, there was a 15-minute big candle—if there had been a -2 funding rate back then, the loss would have doubled. Although a waterfall was inevitable sooner or later, as long as the market maker didn't wipe you out, there wouldn't be a waterfall.
