I don't think you had any idea what an ICO was. You seem to be totally clueless ( or maybe that feedback of you not being the real owner of the account is actually true!)
Why do you talk about Litecoin and Dogecoin in the topic of ICOs?

By the way, there were far more altcoins before ethereum came into the game and some of them are still pushing on despite being low-key.
You can be right about his account but as far as I understand, he did not mean to relate Doge and LTC with ICO instead he said Doge and LTC both had ANN or a discussion thread started first here. I always thought there was no altcoin that came into being before Ethereum but I just checked and Doge, LTC also came before ETH.
ETH was the first ICO project maybe that's why I'm confused here.
Waves must be one of old coin which had roots into this forum:
https://coinmarketcap.com/currencies/wavesIf my memory serves me better, I guess waves did signature campaign as well.
Sounds like a good idea. Still, I like to suggest you do not believe into altcoins because some may fail even after 2 years or even after 5 years also. I am really surprised that we had ICO projects for almost every sector like solar, agri, platforms for doctors, education, drones, file hosting etc etc but I could not recall any one them launched their real time business.
Waves is a good project and if you are talking about this signature campaign then you are right
