Where is good areas to promote/sell/and discuss upcoming ICO?
FB
Twitter
Github
.....
Any other ideas
You probably missed one very good place - this forum!
Promoting in other forums is also fine and you can use ad networks to promote upcoming ICO.
I see there are large number of ico's promoted with google ad sense too.
To many selections on where we can promote the ICO project but I suggest to maximize to promotion on social media sites since there are so many audience staying at there and people would love to see if the project has been funded well by the dev and you will get those investors just like what KickIco did. And yet It is also good to used to furom ads since many people could read and see the header of this furom ads.
