I've heard that holding coins is king. After holding coins for half a year, you directly get a -35% loss, making you look foolish.

With high leverage contracts, if you calculate carefully, the transaction fees alone make it difficult to close your position after opening it. Even if you make a profit, you'll want to earn back the fees before closing, but the market makers' quantitative trading is incredibly precise. Before you can react, they hit you with a blow. How much can you actually earn after considering the transaction fees and the losses from closing your position? In the end, returning to 0 is the final outcome $BTC
