I think Stratis has a lot of potential due to its adoption of the widely used C Sharp as its native programming language. Furthermore, Stratis is offering Blockchain as a Service (BaaS) which is a great feature as businesses can essentially expand their blockchain technology needs on demand via cloud computing. This eliminates the need to invest large amounts of capital in hardware and custom blockchain development. I personally hold a stake in Stratis and see a bright feature ahead! I dont hold a stake in any of the other coins you mentioned, but I'll put them on my research list. Ark smartbride technology sounds interesting!
