Real-world gas fee data from 164 live $USDT transfers today:

Ethereum: $0.13 per tx
Tron: $0.12 per tx
BNB Chain: $0.0024 per tx

BNB Chain is running ~50x cheaper than ETH and TRX for stablecoin transfers, even though 90% of $USDT supply sits on those two chains. Same asset, massively different cost structure depending on the execution layer you pick. If you're moving stables at scale, the rails matter way more than most people think.
