well, a lot people expect a pre block halving pump, but they seem to forget that after the price is pumped significantly, the price will come down again. people will secure their profits and that will lead to the price going down real hard. the price will grow again but it will probably be months after the block halving has been completed. from there it will rise slowly. that's how i think about it.
I also think the same, sure the price will rise with halving but it has to come down again and from there it will start rising slowly as it does right now, so basically we will get back where we are now and will start waiting for another price rise.
Don't expect that the price will reach to the moon at the time of halving, yes of course the price would be much better then now, but if the price drops down, then many users will stop having faith in bitcoins.
