in my opinion we just need to wait and see if the bitcoin price will rise, i personally am holding my bitcoins right now and waiting
The point is that smart people bought because of the halving a long time ago. The price is not going to magically double the day before the halving, but that's what simple people expect. So if you do get a rush of morons buying the day before the halving, it will create a bubble that will pop as soon as the upwards momentum runs out, so if you're buying now, you're basically gambling that you won't be one of the people holding the bag as the bubble deflates.
The time for Bitcoin to increase in price because of the halving has already passed from an economic standpoint because rational markets are forward-looking and liquid markets are efficient, which means the obvious economic reason for a price increase is already baked into the price. The next "halving" related increase will be based on mania, hype, and speculation. If you want to gamble like that, just go play a dice game, as you can get much more reasonable odds.
The price could double to $800 a few months after the halving. But it will reach at least $800 this year.
