The price would rise, the miners would start pumping their saved up bitcoin so the double, so the 12.5 BTC is worth what 25 BTC used to be.
I think the price will rise to a higher level by the halving.
We just need to wait till its so far in my opinion the bitcoin is not to predict, so just wait for it.
If the demand rises during April to July, we can expect a rise in the price. However, transactions may probably take more time to confirm if we don't reward the miners and blockchain may most probably increase their fee as well.
Well last time nothing happened with the price. But yes if the demand starts increasing we can see a nice up movement.
Although i am quite pessimistic at this moment.
Right now we are in a completely different time period. The upcomming block halving will make a lot people panic buy as they are hoping to sell at high levels. Greed will be a major part of the block halving rally with so much investors looking for the jackpot.
