We all expect good things to be happen at the halving or/and at the end of the year, but the number of altcoins which is keeping increasing every month makes me think that the bitcoin price will not go as higher as we expect, but the target of $500 is reachable.
Price of altcoins has little or no effect on Bitcoin. It is the other way round: due to a high network effect, Bitcoin price movements impact heavily the price of altcoins.
