Sorry, but I must say these articles were written for bounty campaign, nothing else! Otherwise, how can you add Hitmex, Optimas Exchange and Blockburn name in this list? Hitmex is totally exit scam, Blockburn scamming with their bounty participants and Optimas has no unique thing to talk about it! It's all waste of time! Well, for other mentioned coins, they are doing better, but sorry no one is capable to be the next big altcoin!
The stock exchange project will not be as smooth as that because it has to face several regulations in its own country such as Hitmex and Optimus exchange will not develop properly because their support is very small and even many exchange projects have failed because there is no support and also lack of skills from the developer.
