Yeah its really unpredictable and we don't know what halving will offer us, as we were expecting the price fo $800 by this time but it didn't happen, not sure what will be the price at halving.
I think the bitcoin price has already risen in the last 12 months, it almost doubled. So it could already price in the halving.
im not dumping any of my bitcoins at the moment, to be honest i honestly believe in a big price increase for sure because i feel that a lot of people will be interested in bitcoins and they will buy it
