A common misconception is "people use Tron because it's cheap" - this is false. Rn, if I pull up the latest USDT transfers, Ethereum L1 costs $0.52 while Tron costs $1.24 (links posted in the next cast). Now, there's some nuance to this, as Tron also has a bandwidth-based system, but the cumulative fees... (contd.)

...still amount to a significant amount because Tron fees are so high. It's likely pure network effects.

I have written a post with some showerthoughts on how to break these network effects: 

A big part of it could be collaborating with CEXs and promoting an L2-based stablecoin

We can't do a naïve average because a) Ethereum has a much higher mix of complex transactions - DeFi, NFTs etc. and b) Tron has a bandwidth-based system, where stuff like TRX are much lower cost. So, we just have to look at what USDT transfers actually cost.

En masse though, Tron is doing ~$1.2 million/day in fees on 5 million transactions, so about $0.25/transfer. Ethereum is pretty close in fees but 1 million tx only, so about 5x cheaper to use Tron (obviously more nuace with use cases). Doesn't Tron have some sort of subsidies too? Been a while since I've looked at it.
