Binance Coin BNB Price Targets after Ethereum Shanghai upgrade

Ethereum’s Shanghai upgrade is scheduled to launch on April 12.
The upgrade will make more than 18 million ether, worth approximately 34Billion, withdrawable, possibly causing a sudden crypto market supply dump.

This is my scenario for Binance Coin:
BNB/USDT short
Entry Range: 315 - 325
Price Target 1: 295
Price Target 2: 265
Price Target 3: 240
Stop Loss: $350
