Just like many popular decentralized exchange platforms for Ethereum, PoloniDex is the one set aside for the trading of Tron and it's tokens in a decentralized manner and allowing users control their assets without transferring to an external exchange. I like the variety of assets PoloniDex allows for us to trade with and most of its pairs are actually TRX. Using the exchange, I was able to eliminate need for paying trading fees by just using my frozen energy to make my trades. I tried using its trading chart which was not good enough for usage as I couldn't see trade history or price movements for any of the candlestick. But I could use it's order book which can prove useful to other users too.
While using the exchange, I found no issues at all. I have seen reviews complaining about Volume and price but that didn't seem to be the case in my experience as all it's unverified tickers were the ones facing such issues. It's a good decentralized exchange and I will definitely be using PoloniDex for a long time.
