As miners reduce production and there are fewer Bitcoins circulating in the market, the price will rise as expected.
It's worth noting that the upcoming reduction in block reward doesn't equate to having fewer Bitcoins in circulation and considering that Bitcoin is still inflationary, I don't think we'll see a significant positive impact on its value
[I hope I'm wrong for the latter part and hodlers would benefit from this event].
No I don't see anything wrong in your opinion as I concur to the part that hodlers will benefit because from this halving many investor will come in and the demand of BTC will rise for those who already hold BTC it will be of very big advantage, most those that practice long term holding who have accumulated BTC over four years plus they stand the chance of have greater profit when the investor will come in when the demand will rise, I stand to be corrected as well but it's my own opinion.
