It's okay, but do we really have lots of uses for TRX, compared to BCH, ETH, DOGE?
I don't know, but zero transaction fees in TRX look like a good fit for micro-transactions. Not sure though how sustainable it is in the long term. Bitcoin had zero-fee transactions in the past too.
I don't think it's sustainable (obviously), why not use doge (a better track record than TRX and fees are still low enough for it to be economical). Even then, I would say ETH is the best bet.
