Bitcoin Rebounds as Miners Navigate the First Post-Halving Week

Bitcoin regained ground on May 17, 2020, while the network’s estimated computing power recovered from an initial post-halving decline. The two developments offered the first meaningful, if incomplete, evidence of how markets and miners were absorbing Bitcoin’s third subsidy reduction.

Kraken’s daily market report placed its BTC reference figure at $9,721, up 4.02%, with $191 million of reported Bitcoin trading volume. The exchange reported $233 million across all markets, making Bitcoin the dominant source of activity in its May 17 report. That was an exchange-specific snapshot, not a universal closing price.

CoinMarketCap’s broader historical snapshot recorded Bitcoin at $9,670.74, up 2.80% over its stated 24-hour window, with a market capitalization of approximately $177.75 billion. The difference from Kraken illustrates why cryptocurrency prices require a named venue or aggregator and measurement window: Bitcoin traded continuously across exchanges, without an official consolidated close.

The first market test after block 630,000

Bitcoin’s programmed halving occurred at block 630,000 on May 11, 2020, at 19:23:43 UTC. Blockchain.com’s block record shows that AntPool mined the block with a 6.25 BTC subsidy and approximately 0.9097 BTC in transaction fees. The preceding subsidy had been 12.5 BTC, so the protocol reduced newly issued bitcoin per block by exactly 50%.

That change did not mechanically require Bitcoin’s market price to rise. It immediately reduced the bitcoin-denominated subsidy available to miners, however, forcing operators to reassess machines whose electricity and operating costs had become difficult to cover. Price, transaction fees, hardware efficiency and power contracts all affected which miners could remain online.

The May 17 price rebound therefore mattered partly because a higher dollar price softened the revenue shock. It did not eliminate it: Bitcoin remained below $10,000 on both the Kraken and CoinMarketCap records, while each block still carried only half the previous subsidy.

Hash rate recovered, but the estimate was noisy

A contemporaneous Decrypt report, relying on BitInfoCharts, said Bitcoin’s estimated network hash rate reached approximately 103 exahashes per second on May 17 after falling to about 87 EH/s on May 14. The report connected that decline to miners switching off less-efficient equipment after the halving.

The word “estimated” is essential. Bitcoin does not broadcast the combined rated output of every mining machine. Services infer hash rate from observed block production and the network difficulty. Blocks arrive irregularly, so a short-window estimate can jump even when the underlying fleet changes less dramatically. The movement from 87 EH/s to 103 EH/s should consequently be read as evidence that block production was consistent with a recovery—not proof that a precisely measured 16 EH/s of equipment returned.

Difficulty had not yet adjusted to the reduced subsidy or any sustained departure of miners. Blockchain.com records block 630,000 at a difficulty of about 16.10 trillion. Bitcoin changes difficulty only after each 2,016-block period, meaning the network initially had to work through the existing setting while miners adapted.

What May 17 established

The verified record supports a restrained conclusion. Bitcoin’s market price strengthened on May 17, and the available hash-rate estimate recovered from its May 14 low. Together, those observations argued against an immediate breakdown in either trading demand or block production during the first six days after the halving.

They did not establish that the mining industry had completed its adjustment, that every operator remained profitable or that the price would follow a particular longer-term path. One day of exchange data and several days of inferred hash rate were early indicators, not a durable trend. The consequential development on May 17 was the network’s initial resilience under sharply reduced miner subsidies, with important questions still unresolved.
