Last week bitcoin try to break $4500 about three times but to no avail! I think above $4500 is possible before the end August as the momentum is very high and bitcoin Cash has rise significant for the past two day to close at $870 yesterday, I think very soon bitcoin Cash traders will start to take profit and fund will flow back to bitcoin.
I don't think bitcoin will above $4500 before the end of August, because bitcoin segwit postponed until the end of the year, and I think that's what caused the price of bitcoin previously will increase but not occur.
bitcoin likely will remain stable at $4000 until the end of August.
