The bitcoin halving will have little impact over the btc world,because we are heading towards the 21 million global limit.There are plenty of btc in circulation and the reduced block reward won't have any influence over the market(other than the usual hype).
Naturally it should have impact but we might not see the impact because every time I see that a factor that is meant to increase the value of bitcoin comes in, it gets pump really , but people who will always take profit to force the value down again thereby making it looks as if there was no impact.
For this reason, I am not really putting my mind that much or hoping too much on the impact the halving will have, if it does have, fine and if doesn’t, market will always rise irrespective of the circumstances surrounding. The halving is almost here, barely a year more and we will know if what we have all speculated will happen or not.
