Yes,bitcoin price could soon reach $4500,especially after november thsi year,when segwit would get completely locked in and transaction fee would get reduced very much ensuring fast transactions at lower fe which would encourage more people to use bitcoin for transactions which would increase demand for bitcoins leading to increase in its price.
If demand increases, it will allow bitcoin prices to be higher this month or in the future. I think that if bitcoin prices have come to a price of $ 4500, I think there will be so many people who will sell the coins they have.
