There can be some correction, both from whales and from BCH camp, but it will be small dip. Price will eventually go up because there are too much people buying it now, there was a increasing of thousand of people subscribing to coinbase.
Nothing can stop bitcoin now. The only question is how to make use of the dips, how to predict them so that you can maximize your profit.
I think also that "nothing can stop Bitcoin" but I doubt that this means an eternal bull run. It is possible $4500 will be the top for some months. We had a short term head and shoulders pattern in the last two days (three highs with the one in the middle being the highest). That is often a trend reversal pattern.
The increases in the last days were very strong and I expect that there are many people selling now to take some profits. Maybe it will only be a short term bottom and the bulls start a try for $5000, but I'm almost sure it won't go higher than that, for now.
(I have incorrectly called the top at $4000, so maybe I'm wrong again
).
