I think both could co-exist but I like disruptive ideas and one should keep a close eye. Regarding Bitcoin, in my opinion at the moment it is overbought. We should expect a correction after the fork, unless we are actually in a real bubble.
I second that! Bitcoin is currently overbought by the investors because they will receive free segwit 2x after the fork on November 16th. This fork is receiving support from the crypto communities worldwide and riding high on expectation. So a correction is unavoidable after the fork. Mostly the short term investors will pull out their funds which will cause the correction. However, I am sure that the correction won't be very drastic, it will just be a little correction and make the base stronger for bitcoin to take another leap.
