DragonEx is a crypto / digital asset exchange that originates from Singapore, it also supports blockchain based technology games.
Apart from that, it has its own token, which is named Dragon Token with a total supply of 37,339,500 tokens, with the normal average exchange fees of other global exchanges, or around 0.2%, also supports Android and iOS applications, for Windows I have never tried it, unfortunately in my opinion the web is too heavy.
The Dragonex trading market itself is USDT / BTC / ETH, I hope there is a BNB and BCH trading fair.
DragonEX has also established an academy on September 10, 2018. It seems that DragonEX Academy aims to provide education when it comes to blockchain technology and investments in the blockchain. They seem to want to provide the education required to be able to differentiate between quality and bad projects in the crypto space.
