Even though the person (or people) who made Bitcoin, known as Satoshi Nakamoto, vanished over a decade ago, they still have a big effect on Bitcoin today.

This week, something that Nakamoto set up in Bitcoin called a "halving" is happening. It's a big deal because in the past, when a halving happened, the price of Bitcoin usually went up. This next halving is expected to happen on Saturday.

So, what's a Bitcoin halving? It's all about how Bitcoin work

Nakamoto wanted there to be only 21 million bitcoins ever. To make sure of this, the reward miners get is cut in half every 210,000 blocks they add to the blockchain, which happens about every four years.

The upcoming halving will happen early Saturday morning in the US and UK. The reward for miners will go from 6.25 bitcoins to just 3.125 bitcoins for each block they add. This process will keep going until all 21 million bitcoins are out there, which should be around the year 2140.

What does this mean for Bitcoin's price? Well, when there are fewer new bitcoins, the price should, in theory, go up if people still want them just as much. After the last three halvings, the price did go up by an average of 16% in the 60 days after. But it's not always a smooth ride; sometimes the price drops for a while before it goes up again.

Experts say that the halving means less supply, so the price could rise, but it might take a while to see a big peak in price. Bitcoin's price has been a bit of a roller coaster lately, but it's still doing pretty well this year, being up 40%.

But there could be some downsides. Mining companies that make bitcoins will earn less money, which could be tough for them, especially if they pay a lot for electricity. And if Bitcoin doesn't get used more for everyday stuff, the miners won't make enough from transaction fees to keep going.

Also, there's a worry that regular folks might get too excited about any price increase and jump in without understanding the risks. Bitcoin has become more accepted, and now there are even funds that track its price that you can buy and sell like stocks. But even with this, some people are still not convinced Bitcoin's price will shoot up because of the halving.

One finance professor thinks any price increase from the halving won't last and that Bitcoin doesn't have any real value—it's all just speculation. So, while the price might hit a new high, she believes it won't stay up forever.
