Do someone here know about bitcoin halving?
Is there a problem when bitcoin halving hits?
Is it better to buy bitcoin when bitcoin halving come?
Seems you are very new here because last summer bitcointalk was full of threads about bitcoin halving. Btw everyone thought that price would be high after halving but it was still same and stable for some time. Bitcoin price rised these months, not after halving. Maybe everyone will give you recomendation about buying bitcoins before halving but I mentioned that price was still same after last halving.
The price didn't rise after the last having because, first, it had been heavily hyped before the halving and corrected massively just prior the event (which should have been expected), and, second, the largest Bitcoin exchange, Bitfinex, was hacked in about two weeks after the halving. But this doesn't in the least mean that the halving had no effect whatsoever on Bitcoin price. It just took some time to kick in. Thus, you should keep in mind that Bitcoin halving is not so much a stand-alone event but rather a lasting process
The results of which may become noticeable only a few months later
