Bitcoin: Halving Mining Rewards - Thursday Morning

This halving means that half the bitcoins that will ever exist were mined - their number will never exceed 21 million.
Opinions on the impact of this event on the market are divided - someone says that mining on the GPU will no longer be profitable and we will face a drop in complexity, someone will expect a boom in the exchange rate, someone thinks that the upcoming drop in bitcoin supply has already been realized by all market participants and is included in the price.
