With many other infrastructure projects coming to life, Ether will have to deal with others like NEO, EOS, and ADA...
Although Ethereum will have to compete with these projects, it will not fall critically. Probably, its price will be not growing as fast as before, but ETH will gain. I love this altcoin, and I am going to hold it.
The projects that are welcomed through Ethereum so it should not make the price any lower than what it is.
