After the halving, prices exploded more than 15 times in just 4 months.
Now: 15M coins in circulation
50 to 25 still seems ample, whereas 12.5 begins to feel like a small number suggesting scarcity.
So what you are trying to say is that BTC price will increase due to scarcity because of the upcoming halving?,
Well for me I can only say that the price for now will rise because of the people speculations that the halving might have an effect to BTC price due to scarcity of the said coin.
But it is just the speculations that makes people buy and buy more BTC thus making it's price higher and it is not the effect of the halving in the end, because even though 25 million of BTC had been in circulation in future there are no BTC that will loss from that circulation and it will continue to be trade even there is no mining anymore, let's keep in mind that even BTC are not consume or loss when use in market but it is only traded.
