TRON is not only about low fees. It's EVM compatible which makes it easier to port Ethereum code to TRON. And they took some really good features from other chains.
Yes, this is another advantage that the TRON token has and not other tokens in the crypto space, meaning that TRON has unique things that can benefit everyone who uses it for different purposes.
Many are speculating to switch to TRON because ethereum's gas fees are very high, especially for those who make transactions that are not large. but it seems that a person's habit factor is very unaffected, many do not want to innovate and stick to ethereum. It will still take some time for tron to give many ethereum users confidence that tron can do better.
Therefore, it is certainly not easy because Ethereum is still very well known and recognized for every transaction.
