You forget couple things here:
1. Price of BTC already skyrocketed more than 60% BEFORE the halving - in anticipation for this event.
yeah, i understand that. and i am not analyzing the price and the future of it here. i am just simply pointing out the big mistake that i have been seeing on bitcointalk for a while. and in the past 3 days i keep seeing new topics saying "why is there no rise because of halving?"!
2. Halving is not "DOUBLE BTC PRICE SWITCH ON/OFF"
3. After 1st bitcoin halving price didn't go up immediately as well.
4. It need time to react to decresed reward per block - it could take months before new stable higher price BTC will emerge.
well, i am trying to say the same thing, sorry if it was not clear enough.
put the cart before horse means doing things in the wrong order, or expecting effect before cause.
