...Is that what's happening right now? The classic age-old investing advice? Everyone's buying like crazy on the "rumour" in preparation for a big dump on the news? It would have to be a pretty big dump to counter-act the sudden mining supply halving, but whatever, sentiment can be pretty strong in either direction.
Well, buy the rumour, sell the news. That's a great advice to have. Although I think halving is a different scenario because it's not a rumour, nor will it ever be news. It's a fact and it will remain fact after the halving.
The halving will have an effect on the supply and demands of bitcoin. And that's why it's going to drive the price up.
