Well, usually with this kind of bonus, there is a locking period so the prices are not dumped, I will enter an ICO that gives me a lot f bonus, and also to lock it, i don't mind waiting, but it appears that is not the case here, so lets hope the project is not dumped much, the price will rise eventually, but after how  much time?

I don't think there is any formal system to decide that.
It is up to the developers to conduct research before launching a project in order to prevent having a duplicate ticker symbol, else this will be a problem when listing on exchanges: the first one to list on an exchange will prevent the other from listing with that ticker on that particular exchange.

They should think about some kind of group thing like its currently on facebook. Where you can promote your old stuff to a informal group of people who are interested

I also think that social network is a nice thing to build a marketplace, that connect people, so it’s easy to build a community and make a marketplace work. Sphere could do that in the future but first they will build a social network platform.

Why do you want to stop the progress of crypto? 
 

There are better blockchain out there better than Ethereum, I am waiting for Stratis. Sphere will do better with Stratis, it is C# dot net and will do better for web programming.

A lot of projects start from Ethereum and than swap tp own blockchain. Hope devs here will do same? Own blockchain always better

hopefully there will be in future also an option with which the user can decide (like facebook) who to show their posts (stuff on marketplace) to friends, friends of friends or worldwide

Hey guys, I just came across this article and have found some absolute gold in here. It has literally changed the way I choose and buy ICOs. Whoever wrote it was extremely kind to share these insights..he's clearly a veteran and knows his stuff. It is ABSOLUTE GOLD!
