比特币“诞生”16年后,挖矿难度再创新高
16 Years After Bitcoin's 'Birth', Mining Difficulty Hits A New Record High

今天是比特币创世块诞生 16 周年,该创世块引入了 50 BTC。从那时起,超过 877,000 个区块已添加到网络中,每个区块都包含交易数据。网络安全性大幅提升,算力突破1000EH/s,创历史新高。尽管 2024 年发生减半事件,矿工仍在继续扩大业务,提高网络安全性。 机构对比特币ETF的投资激增,管理资产超过1000亿美元。然而,近期的资金外流可能是由于年末税收损失和获利回吐所致。尽管如此,比特币 ETF 资产的快速增长超过了历史上任何其他基金。不断上升的算力和机构兴趣凸显了人们对比特币安全性和长期潜力的信心不断增强。

It's Bitcoin's birthday: The very first Bitcoin block was mined 16 years ago today.

Bitcoin’s first block was mined on January 3, 2009.

Known as the “Genesis Block,” Decrypt reports that Bitcoin’s pseudonymous creator Satoshi Nakamoto minted 50 BTC into existence with the move. 

Since then, 877,665 blocks have been mined and added to the network’s long ledger. On a blockchain, blocks contain data on transactions.

Only miners can add data to the network, and the difficulty level helps prevent unauthorized additions or edits to the chain, as it would take an incredible amount of computational power to take over the network.

And the network is stronger than ever, with mining difficulty reaching a new all-time high mark as the biggest cryptocurrency rides into the new year.

As CoinTelegraph's Alex O'Donnell reports, Bitcoin’s hashrate - the total computing power securing the Bitcoin network - reached a new all-time high on Jan. 3 of over 1,000 exahashes per second (EH/s), according to data from CoinWarz.

That is nearly double the network’s hashrate 12 months ago. According to CoinWarz, Bitcoin’s hashrate hovered around 510 EH/s in January 2024. At the time of this article’s publication, Bitcoin’s hashrate had retraced to approximately 780 EH/s. 

The network’s rising hashrate indicates Bitcoin miners are devoting more computational resources to the blockchain, thus improving the network’s security. 

Miners are continuing to expand production even after Bitcoin’s April halving reduced mining rewards from 6.25 BTC to 3.125 BTC per block.

Overcoming headwinds

In 2024, Bitcoin’s strong performance partially offset headwinds from the halving, especially for cash-heavy mining companies like Riot Platforms and CleanSpark.

Mining firms “acquired other miners with turn-key facilities to increase near-term hashrate and increase their power pipeline,” JPMorgan said in a Dec. 10 research note shared with Cointelegraph

Miners have also prioritized accumulating BTC on balance sheets. In December, JPMorgan raised price targets for four Bitcoin mining stocks to reflect value from the miners’ electrical power assets and BTC holdings, JPMorgan said.

JPMorgan cited the stock performance of MicroStrategy, a software company turned de facto Bitcoin fund, which traded at a roughly 2.4x multiple to the value of its BTC treasury as of Dec. 10.

Bitcoin miners, including Marathon, Riot and CleanSpark, hold BTC treasuries worth approximately $4.4 billion, $1.7 billion and $910 million, respectively, according to the BitcoinTreasuries.net data service.

Institutional inflows

Bitcoin’s rising hashrate — and the resultant improvement in network security — is especially important as institutional investors pour capital into BTC exchange-traded funds and other regulated cryptocurrency investment vehicles.

In November, Bitcoin ETFs broke $100 billion in net assets for the first time, according to data from Bloomberg Intelligence.

Asset manager Sygnum expects this dynamic to accelerate in 2025 as large institutional investors, including sovereign wealth funds, endowments, and pension funds, add Bitcoin allocations.

“With improving US regulatory clarity and the potential for Bitcoin to be recognized as a central bank reserve asset, 2025 could mark steep acceleration for institutional participation in crypto assets,” Martin Burgherr, Sygnum’s chief clients officer, said in a statement.

However, BlackRock’s iShares Bitcoin Trust (IBIT) spot Bitcoin exchange-traded fund (ETF) just saw record-high outflows on Jan. 2.

Isaac Joshua - the CEO of token launch platform Gems - also told Decrypt yesterday that the recent downturn “can largely be attributed to end-of-year tax-loss harvesting by investors,” he explained.

Founder of Obchakevich Research Alex Obchakevich told Decrypt that “the main reason for the outflow is profit-taking by investors in early 2025.”

“At the end of the year, investors and funds often review their investment portfolios, which can lead to the sale of some shares,” he explained.

Though, bear in mind, IBIT surpassed $50 billion in assets under management just 228 days after its launch - more than five times faster than any other ETF in history.
