BNB is a falling knife that people shouldn't touch. Everyone who used BNB to trade with in order to get a fee advantage on Binance has been burned hard now the price has taken a dive from $50 to $15. The amount people thought to save have cost them hundreds or even thousands of dollars.
I wish exchanges adjusted their fees based on how congested the network is, which Coinbase is doing well. Before my account became unusable due to their KYC requirement, I managed to withdraw Bitcoin with fees as low as 1000 satoshis. In times where satoshis more than ever matter, exchanges should consider this fee schedule.
