How long does an ICO take to get onto crypto exchanges?

[blue5dragon]

Hi, I've recentally invested in my first ICO and I've got some of the AGI tokens from SingulariyNet. I was wondering how long new tokens usually take to be put onto exchanges. Was thinking of selling a few of them as they seem very sought after, but don't know when they'll go onto any of the exchanges.

Thanks for any help
