You are righ...but if the demand does not increase...and stay same than now...the btc price will decrease after the halving because even after the halving the nb of coins increases even if it increases less than now.
I'm used about this theory because all my systems turn arround this principle...
If your logic is right, the price of bitcoins should decrease continuously (not just after the halving) because the number of bitcoins is continuously increasing, even if demand remains constant. This is obviously not the case.
You are righ...i were confuse...
IF (I say IF) demand stay same and number of bitcoin increase the price can only decrease...
IF the price is increasing since Bitcoin start it is why the demand is increasing and not constant.
In other words...halving will elp for less decreasing if the demand remains constant.
In 4 years the halving will have less effect and in 8 years till less...
in 12 years we will have so many BTC on the market that the halving will have almost "zero" effect.
