Five months after Bitcoin’s second block reward halving slashed miner payouts from 25 BTC to 12.5 BTC per block, the network is demonstrating remarkable resilience. The Bitcoin hashrate has more than doubled between December 2015 and late 2016, signaling that miners are far from discouraged by the reduced reward structure.
TL;DR
- Bitcoin’s network hashrate has more than doubled year-over-year, reaching unprecedented levels by December 2016
- Five months after the July 2016 halving, mining difficulty continues to climb steadily
- BTC trades at approximately $770.81, up significantly from pre-halving levels around $650
- The second halving reduced block rewards from 25 BTC to 12.5 BTC per block
- Miners appear positioned for long-term profitability despite lower per-block payouts
Post-Halving Hashrate Growth Defies Expectations
When Bitcoin underwent its second halving on July 9, 2016, many analysts predicted that the reduction in block rewards from 25 BTC to 12.5 BTC would squeeze margins and potentially push smaller miners offline. Instead, the opposite has occurred. Network hashrate has surged throughout the second half of 2016, more than doubling compared to December 2015 levels.
This growth indicates that the rising Bitcoin price — which climbed from roughly $650 before the halving to approximately $770.81 by December 8 — has more than compensated for the reduced block subsidy. Miners are effectively earning fewer bitcoins per block, but each bitcoin is worth considerably more in fiat terms.
Mining Difficulty Continues Upward Trajectory
The Bitcoin network’s self-adjusting difficulty mechanism has responded to the hashrate increase with a series of upward adjustments. Every 2,016 blocks (roughly two weeks), the network recalibrates mining difficulty to maintain the target block time of approximately 10 minutes.
With hashrate consistently trending higher since mid-2016, difficulty adjustments have largely been positive. This dynamic reflects growing confidence among miners who continue to invest in hardware and infrastructure despite the halving’s impact on per-block revenue. The increasing difficulty also serves as a security benefit for the network, making it progressively more expensive and resource-intensive to mount a 51% attack.
Price Appreciation Offsets Reduced Block Rewards
Bitcoin’s price performance since the July halving has been a key factor supporting mining profitability. At approximately $770.81 on December 8, 2016, Bitcoin represents a gain of roughly 18% from pre-halving levels. When calculated in fiat terms, miners earning 12.5 BTC per block at current prices are receiving approximately $9,635 per block — comparable to or exceeding their pre-halving fiat revenue of around $16,250 per block when BTC was near $650, though the halving did cut nominal output in half.
The broader cryptocurrency market has also provided tailwinds. Ethereum, the second-largest cryptocurrency by market capitalization, trades at $8.23 with a market cap of approximately $713.9 million. The total cryptocurrency market capitalization stands at approximately $12.36 billion, with Bitcoin commanding the overwhelming majority of that value.
What the Second Halving Means for Miners Long-Term
Bitcoin’s first halving in November 2012 was followed by a dramatic price appreciation in 2013, ultimately pushing BTC above $1,000 for the first time. If history is any guide, the July 2016 halving could set the stage for continued price growth into 2017 and beyond.
For miners, the strategy has shifted toward efficiency and scale. Those with access to cheap electricity and the latest ASIC hardware are best positioned to weather the post-halving environment. The hashrate growth suggests that capital continues to flow into mining operations, with operators betting on Bitcoin’s long-term value appreciation to deliver returns that offset the permanently reduced block subsidy.
The Road Ahead for Bitcoin Mining
As 2016 draws to a close, the Bitcoin mining industry appears healthier than many predicted before the halving. The network’s security has strengthened, hashrate is at all-time highs, and the price trajectory suggests growing mainstream acceptance of Bitcoin as a store of value. For miners willing to invest in efficiency and hold their mined coins, the post-halving environment presents a compelling case for continued participation in the network.
The coming months will reveal whether Bitcoin can sustain its momentum and push past the psychologically significant $800 level. If it does, mining profitability will further improve, potentially attracting even more hashrate to the network and reinforcing the positive feedback loop that has defined Bitcoin’s post-halving recovery.
Why This Matters
The resilience of Bitcoin’s mining network following the 2016 halving is a critical chapter in cryptocurrency history. It demonstrates the economic sustainability of Bitcoin’s issuance model and the market’s ability to absorb supply shocks through price appreciation. For miners, investors, and the broader ecosystem, the post-halving period confirms that Bitcoin’s decentralized security model works as designed — even when the rules change.

hashrate doubling post-halving when everyone screamed miner capitulation, classic. same story every cycle
BTC at $770 five months after the halving and people were still bearish. The difficulty adjustments working as intended, miners who survived got rewarded.
this is why you dont bet against the difficulty adjustment. self-correcting mechanism is beautiful
miners going from 25 to 12.5 BTC per block and hashrate STILL goes up. tells you everything about where price is heading
