₿ 1-5. "What Is Bitcoin Halving? – Why It Triggers Price Surges & Supply Shift 📉"
1️⃣ What Is Bitcoin Halving?
Bitcoin halving refers to the event where the block reward given to miners is cut in half. It occurs approximately every four years as part of Bitcoin's protocol to ensure that its total supply never exceeds 21 million coins.
📌 Definition & Structure
When a new block is added to the Bitcoin blockchain, miners receive a fixed number of BTC as a reward.
This reward is halved every 210,000 blocks, which defines the halving cycle.
First halving (2012): 50 → 25 BTC
Second halving (2016): 25 → 12.5 BTC
Third halving (2020): 12.5 → 6.25 BTC
Fourth halving (2024): 6.25 → 3.125 BTC
📌 Why It Matters
The halving event slows the rate of new Bitcoin issuance, increasing scarcity.
This built-in mechanism combats inflation and enhances long-term value stability.
A halving is not just a technical adjustment; it’s a market-moving event with broad implications.
2️⃣ Why Does Halving Lead to Price Surges?
Whenever a halving approaches, investors anticipate price appreciation, and historically, this has proven true. Bitcoin’s price has shown strong upward trends following previous halving events.
📌 Reduced Supply → Increased Scarcity → Focused Demand
With halving, the rate of Bitcoin entering the market drops, meaning less supply is available.
As a result, scarcity increases, and if demand remains stable or rises, prices tend to go up.
📌 Investor Psychology & Market Sentiment
As halving approaches, investors expect supply to tighten, prompting early buying activity.
This creates a FOMO (Fear of Missing Out) effect, pushing demand and prices even higher.
Media coverage and social media hype amplify this momentum.
📌 Past Price Performance After Halvings
2012 Halving: ~$12 → over $1,100
2016 Halving: ~$650 → $20,000+ (by 2017)
2020 Halving: ~$8,700 → ~$69,000 (in 2021)
👉 In essence, halvings affect not only supply but also market sentiment and trend cycles, creating a compound impact.
3️⃣ Impact of Halving on Miners
While halving may be bullish for investors, for miners it can be a matter of survival. A 50% reduction in rewards can significantly affect profitability.
📌 Declining Rewards & Profit Margins
Following the 2024 halving, block rewards dropped from 6.25 BTC to 3.125 BTC.
This means miners earn half the revenue for the same computational effort.
If Bitcoin's price doesn't rise enough, many miners may not break even.
📌 Energy Costs & Operational Strategy Shifts
Miners in regions with high electricity costs may shut down or relocate operations.
Many are upgrading to high-efficiency ASIC hardware or adopting renewable energy sources like solar or hydro.
Others are downsizing operations or joining mining pools or cloud mining platforms.
📌 Small Miner Exodus & Hash Rate Changes
Halving often pushes small-scale miners out of the market due to lower profitability.
This can affect the network's overall hash rate, triggering temporary difficulty adjustments.
In the long term, this may lead to a more centralized mining landscape dominated by large operations.
👉 Halving isn't just about reducing supply—it’s a transformational event for the mining ecosystem, reshaping infrastructure, economics, and network participation.
