Halvings don't make the price go up. Correlation does not mean causation.
Last time the halving coincided with bitcoin being discovered by the mainstream press. And Cyprus happened when they confiscated people's savings in a bail-in for the banks.
There is no big news to bump up bitcoin this time. It's the opposite - Brexit is a victory for the people, it makes Britain safer as EU rules like confiscating people's savings no longer apply.
There are 2 kinds of pumps we have seen
- The halving which started around november and lasted till april
- China/Brexit which started a month ago.
Both events had a direct correlation as to why the bitcoin price went up, although the brexit event did not influence the price a lot.
