There's no better operation right now than Shorting $BTC

with 101k, 98k as target and Longing ETH with 2764 as target.

It doesn't quite matter how much $ETH falls, 58M will be liquidated at 2764, thus the price will go there.

And it doesn't quite matter how much BTC goes up, there's more than 100M to be liquidated until 98k.

To be sure, use a Max or X2 cross margin on ETH so your liquidation is below 1350.

And to be sure, use a Max of X10 cross margin on BTC so your stop loss at $105800 doesn't hurt you that bad.
