Up to you to buy that prediction or not. As for me, it's just another predictions and speculations we see every day.

Technically, halving will not literally lift up the price but it will give "positive expectations" that will create a positive hype that might result in creating more demands. The process will take some time.

That's why prior to expected halving, expect that those enthusiasts will try to accumulate coins as they can like what they did during 2016 since they already have a glimpse of what to expect years after that 2020 halving.

$20,000, $30,000, $50,000 - doesn't matter if it will be achieved or not after halving as long as we will have a healthy price movement. After all, I just want to stick my speculation on a realistic numbers and achievable figures.
