Tron TRX can be bought on various widely recognized and known decentralized exchanges such as Binance, Kraken, eToro, Kucoin, Gate.io, CEX.io, FTX US, Bitfinex, or Huobi. Some of these platforms (like CEX.io) support only around 20 cryptocurrencies which is probably one of the small reasons why TRX is considered one of the biggest coins in the crypto world.
