I strongly feel there will be a big bubble because of the halving hype, maybe bitcoin can also expect some media interest as bitcoin sale spike up, then the halving process will take its toll on the bitcoin price and then eventually the price will notice increase attracting even more people. That's when it matters, if things continue to go the way they are for bitcoin, then I expect btc to be less volatile too.
I don't think we will experience a bubble after the halving as much as a natural rise as the supply of bitcoin will go down and simple economics mean the price per bitcoin will go up mate

The supply of Bitcoin is constantly increasing, currently at a rate of 7 to 10% per year.
After the halving, bitcoin supply will not decrease -- only the rate of increase will drop to 4 to 5% per year.
which is a decrease if you think about it, a decrease in comparison to what it was before, this will have an impact if the price isn't already skyrocketed due to demand, in that case you will not be able to notice it
