Today the market started to hunt down, it should not go down directly, but fluctuate before going down.

If the strategy I mentioned earlier is followed, hold BTC short order, open a long order at this Reverse position to lock in profits, wait for the upward hunting to end, exit the long order, and add a bit of Position to the short order.
long order mainly opens ETH as the main! Lock in profits for BTC Rebound, and take the opportunity to do a short-term long order for ETH.
