I just looked back at Bitcoin halving history and found some interesting things that many people still don't fully understand. What exactly is halving? It is actually an automatic mechanism within the Bitcoin protocol, where every 210,000 blocks (about 4 years), the mining reward is halved. This event has a very significant impact on the entire system.

About 2 years ago, Bitcoin halving occurred in April 2024. At that time, the reward for each block decreased from 6.25 BTC to 3.125 BTC. I clearly remember the market experienced quite a lot of volatility around this event. Understanding what halving is will help you grasp why Bitcoin is designed this way.

The great thing about halving is that it automatically controls inflation. The total supply of Bitcoin will never exceed 21 million BTC, and there’s no way to increase it. When the mining reward decreases, the amount of new Bitcoin created also decreases, creating scarcity. This is the main reason why investors pay attention to what halving is and when it happens.

After the 2024 halving event, I noticed interesting market reactions. History shows that previous halvings (2012, 2016, 2020) often coincide with significant bullish cycles. But this is not a strict rule; rather, it results from the combination of supply scarcity and market psychology.

One important thing many people overlook is the impact on miners. When the reward halves, mining profitability also decreases. Small miners may have to withdraw if electricity costs are not reasonable. This directly affects Bitcoin network security. If you want to understand more deeply what halving is, it’s a balancing mechanism between inflation, scarcity, and security.

Currently, Bitcoin is trading around $76K. If you're interested in preparing for major events like halving in the future, I see some useful strategies. Holding long-term is one way, or you can apply DCA (Dollar Cost Averaging) to minimize risks from price volatility.

One thing for sure is that halving will continue every 4 years until all 21 million BTC are mined. This could happen by the year 2140. I think tracking these events and understanding what halving is will help you make smarter investment decisions.
