$300 to $320 by end of this year maybe reachable but $600 is unobtainable.
There should be a very good reason why it will shoot up to that level, but for now I think $300 to $320 by end of this year maybe possible.
We need a very big bubble to send the price to be $600. It will not hold there. However, it is possible for the price to be $600 in the middle of next year.
