作为市值最大的加密货币,比特币的价格依然徘徊在1.9万美元附近,然而,比特币的挖矿难度刚刚又跃升了13.55%,这是自2021年5月21.53%以来最高的增幅。

这一激增源于“多重因素的合力”,比特币挖矿公司Braiins的研究与挖矿洞见业务总监丹尼尔·弗拉姆金说。

其一,矿主们刚开始收到交付的新矿机。

弗拉姆金告诉《财富》杂志:“大型基础设施的扩建需要6-18个月的时间,目前正在稳步推进,新设施可接入更多的新一代硬件。”其中包括140 TH/s的 Antminer S19 XPs,该设备“终于得到了大规模的交付和部署。”

该领域的其他人士也同意这一看法,包括比特币挖矿公司比特矿业(BIT Mining Limited)的首席经济学家杨有为(音)。他指出,矿机交付是“主要原因”。

杨有为说:“很多人都知道,比特币矿主自2021年5月中国颁布禁令之后,一直努力寻找新家。一些矿主的行动更快,但随着很多矿主最终安顿下来,该行业的大部分算力到最近才得以恢复。新一代矿机实际上才是主要因素,在去年年底,很多矿主通过远期合约购买了矿机,如今正处于集中交付期。”

第二,先进矿机近几个月的价格亦随着比特币价格的下跌而下跌。

弗拉姆金说,对于以“2021年和2022年初的高价”购买硬件的矿主来说,生产的边际成本将低于比特币价格,但总生产成本将接近或甚至高于比特币价格。

停机时间的减少也是一个因素。弗拉姆金说:“位于得克萨斯州这类地区的矿主在炎热的下午会关停设施,这类现象在过去几个月中一直频繁上演。”如今,夏季已经结束,“停机时间就会大幅减少”。

总的来说,挖矿难度的加大会给大量矿主造成伤害,而且这些矿主在熊市期间一直在艰难地维持着利润率。

弗拉姆金对《财富》杂志说:“只要单位比特币的挖矿边际成本低于比特币价格,矿主们就不会歇业,然而,如果计算硬件成本的话,他们基本上没有多少钱可赚。很多矿主如今都处于这一局面,利润率的下滑让他们感到异常痛苦,因为当前的利润很难抵消近期的硬件购买成本。不过,利润还没有低到迫使其彻底关停的地步。”(财富中文网)

The price of Bitcoin, the largest cryptocurrency by market value, remains stuck at around $19,000—but Bitcoin mining difficulty just jumped 13.55%, the most since a 21.53% increase in May 2021.

This surge is due to “a combination of several factors,” said Daniel Frumkin, director of research and mining insights at Braiins, a Bitcoin mining company.

For one, there’s the latest delivery of new rigs reaching miners.

“Large infrastructure build-outs, which are six to 18 months in the making, are steadily being completed, enabling more new-generation hardware to be plugged in,” Frumkin tells Fortune. This includes the 140 terahashes per second (TH/s) Antminer S19 XPs, which are “finally being delivered and deployed at scale.”

Others in the space agree, including Youwei Yang, chief economist at Bitcoin mining company BIT Mining Limited (BTCM), who notes that the mining rig deliveries are the “primary reason.”

“As many people know, Bitcoin miners have been trying to find their new homes after the China ban in May 2021. Some are quicker than others, but the majority of capacity has not been reached until recently, as many have finally settled,” Yang says. “The new-generation mining rigs are actually a major factor, as [late] last year, many purchased mining rigs via forward contracts, and now is the concentrated delivery time.”

Secondly, the price of advanced mining rigs has declined alongside the price of Bitcoin in recent months.

Miners who purchased hardware at “elevated prices in 2021 and early 2022” have a “marginal cost of production below the Bitcoin price, but a total cost of production close to or even above the Bitcoin price,” Frumkin said.

Less downtime also is a contributing factor. “Miners in places like Texas shutting down during hot afternoons was a frequent occurrence for the past few months,” Frumkin said, and there’s “a lot less downtime” for miners now that summer is over.

Overall, the heightened mining difficulty is going to hurt a lot of miners who are struggling to retain a profit margin during the bear market.

“Miners will stay online as long as their marginal cost to mine one Bitcoin is below the Bitcoin price, but they aren’t truly profitable when factoring in the cost of their hardware,” Frumkin tells Fortune. “Many miners right now are in this situation where the depressed profit margins are extremely painful, making it unlikely to break even on recent hardware purchases. But they haven’t yet hit levels that would force them to shut off completely.”
