This concerns me about what will happen to bitcoin price after 2016 ? Will it crash after the block halving ? Is there any upcoming incident in 2017-18 that may push the price up again ?
I don`t think it will crash after the halving! No way! If the halving decreases the quantity of coins generated by the miners, then the coins become more scarce in the market, so the price increases. That`s the law of the market, my friend.
Well, you have to consider more than just the "law of the market". You also have to realize that there is a potential hard fork coming about, and that there might be uncertainty in where miners should point their hashing power towards/exchange sites knowing which version to support, and so on. There hasn't really been much said to how much notice people will have in advance before the whole thing comes about. I don't think this potential fork will just be sprung upon miners and other bitcoin users all the sudden; but it could very well happen...
Point I'm trying to make, is that there are a lot of things being debated on that could affect the functionality, and therefore, the price of Bitcoin.
