OKCoin International is truly an international Exchange because with its many awesome features, it supports many countries. I do explore my mostly used trade option which is Spot Trade at ease. Although OKCoin International supports many countries to participate in trading on its platform, it only supports the US dollars, UK Euro and the Japan Yen of which I don't know if you would accept it that way but it is still fine by me.
OKCoin International is a very user-friendly Exchange to trade on because I can tell from my experience so far on trading here. To conclude it all, OKCoin International is a good Exchange to invest in cryptocurrencies and I recommend it.
