I just noticed that withdrawing from Binance using BTC is ridiculously expensive compared to BNB, which is almost nothing. So I was wondering, why am I not using it? Why don't YOU use it? I feel like there is a catch, just don't know what it is.

1) I use USDC to trade. Should I switch over to BNB? Why? Why not?

2) What are the advantages? Is it only to save on fees? If so, would there be any disadvantages that would negate that benefit?

3) Do I have to pair the crypto I'm reading with BNB in order to use BNB to avail the low fees? Or can I just exchange currency for some BNB to hold in my wallet and Binance will use that BNB to pay fees?
