What Is the Bitcoin Halving?

The Bitcoin halving is an event in which mining rewards are cut in half approximately every 210,000 blocks (about four years). It is a core design principle of Bitcoin and a deflationary mechanism that gradually reduces new issuance as Bitcoin moves toward its total supply cap of 21 million coins.

The 4th halving, which occurred in April 2024, reduced the block reward from 6.25 BTC to 3.125 BTC. At the 5th halving in 2028, the reward is expected to fall to 1.5625 BTC.

Historical Post-Halving Price Data (Fact-Based)

1st Halving (November 28, 2012)

The 1st halving took place when Bitcoin was still known only within a small technical community. Because the market was small, price swings were extremely large.

2nd Halving (July 9, 2016)

During the 2nd halving cycle, Bitcoin surpassed $10,000 for the first time. Combined with the ICO boom, it rose to nearly $20,000 by the end of 2017.

3rd Halving (May 11, 2020)

After the 3rd halving, major purchases by institutional investors (Tesla, MicroStrategy) began, pushing Bitcoin to new all-time highs.

4th Halving (April 2024)

The 4th halving was an unusual cycle because it coincided with the approval of Bitcoin ETFs (January 2024), and Bitcoin had already reached a new all-time high before the halving.

Price Scenario Analysis for the 5th Halving (2028)

Pattern Analysis: A Diminishing Returns Curve

Looking at the one-year returns after past halvings, a clear law of diminishing returns can be observed:

• 1st: +7,995%
• 2nd: +292%
• 3rd: +543% (boosted by COVID-era quantitative easing)
• 4th: +33% (ETF effect priced in early)

If this pattern continues, the upside after the 5th halving is likely to be more limited than before.

Scenario 1: Bull Market (Probability 30%)

This scenario assumes continued inflows into Bitcoin ETFs and expanding global liquidity. Bitcoin could reach $200,000-$300,000 within one year after the halving. This scenario becomes realistic if it overlaps with a U.S. Federal Reserve rate-cut cycle.

Scenario 2: Gradual Upside (Probability 45%)

In this scenario, institutional capital continues to flow in steadily, but volatility declines as the market has already entered a more mature phase. Bitcoin could stabilize in the $120,000-$180,000 range after the halving.

Scenario 3: Sideways Market or Correction (Probability 25%)

This is a scenario in which the market stagnates due to tighter global regulation, an economic slowdown, or the emergence of new competing technologies. The possibility of long-term sideways movement around the $80,000-$100,000 level cannot be ruled out.

Points Investors Must Remember

The Bitcoin halving is a supply-side event, and the actual price is determined by demand. The halving itself does not guarantee a price increase. Historical data is only a reference, and investment decisions should be made carefully within your own risk tolerance.

When using leverage, make sure to calculate your liquidation price. You can use our Liquidation Price Calculator to check the exact liquidation price.

💡 Practical Insights

Other blogs simply repeat the generalization that "halving = guaranteed price increase," but from the perspective of Korean investors, the most decisive variable is the KRW-USD exchange rate. As of November 2024, with the KRW-USD exchange rate above 1,400 won, even if BTC rises +30% in U.S. dollar terms, the return in Korean won falls to +20% if the exchange rate returns to 1,300 won. Based on my own experience during the third halving cycle in 2020-2021, the kimchi premium on Korean exchanges (Upbit and Bithumb) widened to an average of 5-8% around 6-9 months after the halving. At that point, using triangular arbitrage to capture the gap with overseas exchanges (Binance) increased annualized returns by 12-15 percentage points compared with simply holding. In addition, after the Korean National Tax Service begins taxing virtual assets in 2025, gains on sales will be subject to a separate 22% tax (including local tax), so a key tax-saving strategy is to hold through the halving cycle for more than one year and avoid aggregation with comprehensive income tax. Considering that, according to Statistics Korea's 2024 Household Financial Welfare Survey, the average financial assets of Koreans in their 30s and 40s are about 84 million won, the most realistic risk-management ratio when entering a halving cycle is to scale in within 5-10% of total assets. Finally, just as the ETF pre-pricing effect reduced returns by +33% during the fourth halving, before the fifth halving, the 2027 U.S. SEC altcoin ETF approval schedule and the timing of phase 2 implementation of Korea's Virtual Asset User Protection Act are likely to act as variables that get priced in ahead of time.

Frequently Asked Questions (FAQ)

Q1. Exactly when is the next Bitcoin halving?

A: The fifth Bitcoin halving will occur when block height 1,050,000 is reached, and based on the current block production rate, it is expected around March-April 2028.

Q2. Is it better to buy before the halving or after it?

A: Historical data shows that the strategy with the highest returns has been to buy 6-12 months before the halving and sell 12-18 months after it. However, past performance does not guarantee future results.

Q3. What happens to Bitcoin when halvings stop?

A: Bitcoin's final halving is expected around 2140. After that, mining rewards will become zero, and miners will operate solely on transaction fees.

Q4. Does the Bitcoin halving affect altcoins as well?

A: Historically, in bull markets after Bitcoin halvings, altcoins such as Ethereum have tended to rise as well. However, there is usually a lag, and altcoin season typically arrives 2-4 months after BTC rises.

Q5. What is the biggest risk in halving investing?

A: The biggest risk is excessive leverage. Volatility tends to peak around halvings, so high-leverage positions carry a very high risk of liquidation.

Q6. Where can I check the Bitcoin halving countdown?
