I have sold all my holdings in hydro and Contentos when I found out it was just normal business to the founders and everything written on the Whitepaper was only a gimmick. I am looking to buy an coin that seeks to serve the IoT industry, its called Mtcn from the parent company of Multiven. They have a running dapp (Multiven.io) at the moment where you can purchase loads of IT and IoT devices ranging form softwares to phones and laptops with its native token. I may be holding this one for long if I am done with my research.
