You can do some copycats based on the market situation. If $BTC rebounds, don't short other copycats for the time being, because it is normal to have a rebound after a general decline.

But if the market trend continues, the support near the current price of $FIL cannot be sustained. In fact, you can directly place a breakthrough below the support, and then stop loss back to the current price, which also has a two-to-one profit and loss ratio.
