ChainDD is a platform that was designed by the Chinese people. The proof is in the fact that their interface is available only in Chinese, not too good to serve as a means of targetting the global market. The platform doesn't really look like a crypto wallet, I must confess. The fact that I couldn't understand what they wrote there (because everything was written in Chinese) doesn't mean I can't predict what might be there. I could barely see things related to cryptocurrencies on this platform.
The wallet is known to support a wide range of cryptocurrencies but I don't really see it as much, it can be considered moderate and not a multi crypto storing wallet. The only thing I seen to love about this platform is the fact that they have mobile applications for both the Android operation system and IOS. The language stands as a major barrier to me.
