The World Digital Mining Summit (WDMS) 2023, held in Hong Kong from September 22-23, brought together key players in the Bitcoin mining industry to discuss the latest trends and developments. One of the core themes that emerged from the summit was the growing focus on efficiency and renewable energy.
In line with the crypto industry’s commitment to sustainability and cost-effectiveness, Bitmain, a leading cryptocurrency mining hardware manufacturer, launched its much-awaited Antminer S21 and S21 Hydro ASIC miners at the summit. The Antminer S21 has a hashrate of 200 TH/s and an efficiency of 17.5 J/T (joules per terahash), while the S21 Hydro has a hashrate of 335 TH/s and an efficiency of 16 J/T.
These figures are significantly better than most previous Bitcoin ASIC miners, which typically operated above the 20 J/T threshold. The improved efficiency of the Antminer S21 and S21 Hydro is good news for Bitcoin miners. It means that they can mine Bitcoin more profitably, even with lower electricity prices. It also bodes well for the environment, as Bitcoin mining becomes more sustainable.
The pivot towards efficiency and renewable energy is being driven by two key factors. First, the relentless increase in electricity costs is making it increasingly important for miners to reduce their energy consumption. Second, the impending Bitcoin supply halving will put additional pressure on miners’ profitability. By increasing their efficiency and switching to renewable energy, miners can reduce their costs and improve their bottom line.
In addition to the environmental benefits, there are several other advantages to using efficiency measures and renewable energy in Bitcoin mining. For example, miners that use renewable energy sources are less exposed to fluctuations in the price of electricity. Additionally, miners that are located in regions, where renewable energy sources are available, often have access to cheaper electricity rates.
A recent report shed light on how miners are witnessing a drop in their Bitcoin mining profits. The upcoming Bitcoin supply halving, expected to occur in April 2023, will also halve the block reward for miners, making it even more difficult for miners to remain profitable. To mitigate this challenge, miners must either increase their reliance on sustainable energy or improve the efficiency of their ASIC fleets. Those who focus on efficiency and sustainability will be better positioned to weather the storm of the halving and remain profitable in the long term.
