now I plan to add EOS to my portfolio, I think EOS will compete with ethereum because currently EOS is widely used as an ICO contribution tool and this will make the value even higher
May be you are right that EOS is used for ICO contribution but many people think that EOS is scam and there is no future of it. I dont know how it can go with Ethereum. Ethereum is the second biggest crypto in the world and the top in Altcoin, while EOS is far behind and to my view there is no competition between EOS and ehtereum. You should understand this.
