I only know that within 3 years, Ethereum's price range will definitely be able to break through, reaching 6000 and then retracing to 2000.

Therefore, I choose to open both long and short positions around 4000, with a futures-based long position and a coin-margined short position. The liquidation price for the long position is maintained around 1500, and for the short position above 8000.

Whenever the profit exceeds 800 points on either side, I take profit on one lot, then return to around 4000 to add more positions. Of course, I will encounter extreme one-sided market conditions, such as the price plunging to 1800, where I can also take profit on the short position in USDT futures and buy spot to hedge the coin-margined long position. At that time, the liquidation price should be pulled below 500. The same logic applies during a rapid surge!

Although there is a high probability that one side will eventually get liquidated, I am considering how many times I can profit within the 800-point range around 4000 before a large one-sided move causes a liquidation.
