Things are very exciting in my opinion
There are many projects trying to replicate Bancor's concept (decentralize/autonomous exchange)
At the moment Bancor is by far the most developed and has the pioneer/first-mover advantage, but there is only one shot to get this right
In my opinion the biggest advantage of a decentralized exchange is that people can quickly visit the site, exchange their token for whatever and leave (without logging in, submitting personal info etc.)
I hope the Bancor team is considering "splitting" their product/service in two parts
1. A "Shapeshift" like portal for anyone to quickly make their exchanges
2. The Bancor App for anyone who wants to store or issue their own currency, ICO etc.
If these two services will not be offered separately (having to log-in the Bancor network for example to execute an exchange) people will most likely shy away and find a more faster/convenient way to exchange their cryptos (0x)
