Not only because Vitalik is an adviser for Kyber
but also other pros and cons
Pros:
Decentralization. This seems a necessary trend ,because of China recent news about banning exchanges.
But KyberNetwork is not only exchange. It will also allow to swap and send almost instantly any tokens in Ethereum network.
It will be much more secure than any of centralized exchange,faster ans cheaper.
Cons:
To be as good as centralized exchange Kyber will need to have a good volume and liquidity. Thats means users! In other way we will not get acceptable speed.
But as it was distributed throw ICO hopefully all token holders will use KyberNetwork as a future platform and will promote it to other, because what it gives to our community.
It was just started on EtherDelta and Liqui and allready almost x4 of its price.
When it will hit other big exchange no doubt price will increase more.
I was not able to participate in ICO and will buy on exchange. I personaly would take the risk
