TRX has more upside potential as it hasn't surpassed its ATH yet. TRX is a blockchain with many DEFI, NFT applications and it is being chosen by Tether to print USDT.
This project has the potential to be more profitable than LTC.
First, why is the title thread not in english?
But lately, I am using TRX for transfer purposes because of its cheap fees.
So will be choosing TRX over LTC at the moment.
Aside from that, as you mentioned, they have different applications already.
No wonder Tether chose them as they really have very minimal fees even using the USDT - TRC20 network.
With LTC, I am not really familiar with their applications or current developments, other than the fact that it is an old alt.
Second that. TRX has a notable real-life use for USDT TRC20 already and I doubt smth close to this can happen with LTC. There are thousands similar to LTC cryptos from DOGE to smth like "BTC-diamond-global-cash-coin" already, how the LTC is different?
