I think its good for bitcoin because most of the newly created coins now are in ethereum blockchain amd it made no difference to ethereums price in the market so in bitcoins case, I dont think there is a threat if alrernate coins are created in bitcoins blockchain.
Yeah this is also very much true. As ICO's are forming day by day but with no real progress in the ETH platform as they dont really contribute to the value. If they would have increased the value of ETH then it could have had bad effects on the BTC as most of the people would have gotten attracted towards the ETH more.
This would have been really bad for the bitcoin economy. Thankfully there is no progress in the ETH value due to ICO's!!
They are anyway different sphere so lets not get worried about because of the altcoins.
Basically, this is not about ETH but BTC, but since you mentioned that, I am not sure what you actually mean by not bringing any value. As far as I am concerned, as long as Ethereum is usable, that makes it valuable and whatever happens on the Ethereum blockchain in terms of development has to do with the developers and not the tokens.
They are all there for their own purposes and serve their own various needs for the users, and in this case, I am referring to those with products, and as long as they are on the Ethereum blockchain, they sure do have a role to play. Overall, for bitcoin, I do not see any problem that altcoins could have created.
