We’ve already discussed what happened in the last two halvings and it is believed that the trend would continue. However, nobody can tell for sure if this time also the price is going to increase only. We saw the first demonstration of how people would react to Bitcoin halving in 2012 when the prices started to rise after some time. Then on the second halving initially, we saw little drops in the prices of Bitcoin but it gradually increased over the course of the year.
So, the theory of Bitcoin halving is that when the Bitcoins supply declines but the demand stays the same, it pushes its price up. Now, if this theory has some truth, we would see an increase in the prices of Bitcoin this year as the halving has started showing its effects on the prices of Bitcoin already.
Although, as of now not most people aren’t aware of Bitcoin halving 2020 and its effects, it is likely if enough people know about it in advance, the prices would instead increase before halving.
