$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.
May be or may not be. But my prediction would be around $500 to $600 range by the end of this year we can see bitcoin there. Everybody is getting ready for halving which is the most anticipated event factor for the bitcoin price upward surge.
