a subsidiary of google.com. namely youtube.com and blogger.com have started blocking videos and articles that contain elements of ICO, tokensale, and Altcoin. then how is your prediction for the future of altcoin?
There are other venues where icos and crypto can use for advertisement. It will affect ICO and its progress but I do not think that it will cripple it. Facebook, twitter, youtube, google can ban crypto advertisement but it will still survive.
