Bitcoin will crawl slowly because of many impatient investors that sells immediately when price starts to rise. But i am positive that it will rise to 25k$ this December. The issue on icos is not the thing that presently affects the upward movement of bitcoin. I think the whales is one of the reasons plus the unending negative issues which also affects the investors solid trust to bitcoin.
On long term these impatient investors will waste a precious chance... Bitcoin will grow and they will stay back with the hands full of worthless tokens, coins. I would like to be positive like you about Bitcoin's price by December, but I don't see reasons why it would hit such price in time.
I think ICOs represent a very important principle of Crypto-Currency world, that is the decentralization, and I agree with you, they aren't a threat to Bitcoin. As the thread's author says, there are many weeds around the big "Bitcoin tree", but where there is a big and strong tree, the little weeds don't grow up, they die and their remains fertilize the big tree to continue developing itself even more!
