Halvings are very important factor, not only in a technical, but in a psychological sense. In next halving reward per block will go from 12.5
BTC to 6.25
BTC and will have 18.37 million
BTC mined at that time. The fact is that less and less bitcoin is left for mining, and that halvings will cut block rewards every 4 years, with limited supply - could cause significant increase in price. However, all depends on demand for bitcoin in next years and whether people accept bitcoin as store of value or cryptocurrency.
When it comes to bitcoin nothing is impossible, and therefore should not be dismissed possibility of six-digit numbers. Most major investors mostly agreed that this is possible, the only difference is when this could happen. Based on past halvings
big things mostly happen 6+ months after halving, and in next year.
The only difference from the last halving is that base price for big pump was under $1000, and after next halving we can easily have x10 from that price. If we know that is possible to go from $1000 to $20 000 in one year, maybe it's possible to imagine $10 000 to $100 000 in next bull run
