I think we can goes over 500 for halving. perhaps before halving we could reach 500, then after halving it could rise higher.
Yes, I'm pretty sure bitcoin value will increase before bitcoin halving come. Many people are now on panic buy that the value of bitcoin will rise before bitcoin halving, it's making the demand go higher and the value increase too. But unfortunately it will not rise higher after halving, because people that do panic buys will most likely sell their coins after the event comes. This will make the demand fall and will directly effect the value of it, what will happen? Will result to dump value of the coin. By conclusion, before halving bitcoin's value will bubble because of increase in demand and once the halving come it will dump because of people that will sell their coins for a chance to take a profit into it.
