I learnt that the ethereum fork will bring about reduction in reward per block for miners from 3ETH to 2ETH thereby causing Ethereum to be scarce.
My question is will the scarcity bring about signifant increase in price?
Yes as the number of Ethereum that should be in circulation will be very scared and we should expect very high in Ethereum pricing. However, on the normal bases this should happened since yesterday but that was not possible but now we have very bad market and after the fork we would see what is going to happen.
