A historical event in Bitcoin, that is Bitcoin Halving.
Bitcoin Halving is the process that occurs roughly every 4 years which reduces the Bitcoin mining reward to half.
Currently, the award for mining one block is 12.5 Bitcoin which is going to reduce to 6.25 Bitcoins.
This is very bad news for Bitcoin miners because now the same amount of work will give just half of the current reward.
So what may after the halving?
Bitcoin demand will be the same but the supply of Bitcoin will reduce after the halving so there may some chance that price may increase after some time but this is just an idea (not advice) based on previous Bitcoin Halving happened.
