Interview with BTC.top’s Jiang Zhuoer

After a tumultuous 2020 that continued into Bitcoin (BTC) setting new all-time highs in 2021, Bitcoin miners are dealing with a bittersweet state of affairs — income have skyrocketed, however a number of points stop them from shopping for extra gadgets and boosting Bitcoin’s hash price.

According to the founding father of main mining pool BTC.Top, Jiang Zhuoer, world electronics provide chain points are having their impact on the mining business as properly. Speaking with Cointelegraph, he mentioned:

“There is definitely a shortage of equipment right now because, since the coronavirus epidemic, the global supply chain has been interrupted and is now in the process of gradually recovering. But the demand for chips has greatly increased, so now all industries are short of chips, whether it is Bitcoin mining or other industries, such as consumer electronics or even the automotive industry.”

Recently, automobile manufacturing big General Motors shut down a few of its crops as a result of incapacity to supply chips. Other carmakers have seen related shutdowns in current months as properly.

The scarcity of mining gadgets will be simply seen in Bitcoin’s hash price. Since the halving in May 2020, Bitcoin’s hash price has elevated from about 92 million terahashes per second to its present studying of 166 million, an 80% improve. Bitcoin’s worth, however, elevated from $9,000 to over $46,000, a achieve of over 400%.

Bitcoin’s hash price has a comparatively simple correlation with worth. Barring new technological advances, will increase in worth must be carefully mirrored by will increase in hash price. While the speed of recent gadgets coming online ought to lag behind the value in bull markets, the hash price has remained comparatively stagnant prior to now few months.

This signifies that present miners are seeing a lot greater income for particular person gadgets, which, added to the scarcity, leads to inflated unit costs for ASIC miners. According to ASICMinerValue, obtaining a Bitmain S19 Pro proper now prices about $9,000, whereas its official worth is lower than $4,000.

According to Jiang, the mining business additionally noticed main points in 2020 on account of Bitmain’s inside energy battle. “The indefinite delay of the Ant mining machine S19 in June, July and August 2020 caused us a lot of difficulties. We underwrote our customers according to the shipment period and used our own machines to make up the revenue to our customers,” Jiang mentioned. With the Bitmain saga being resolved in favor of Micree Zhan, there must be no extra particular points with buying the corporate’s miners.

Bitcoin ASICs hitting basic efficiency limits

Despite the number of points, 2020 was additionally a pivotal yr for the Bitcoin mining business as a result of launch of new-generation ASIC gadgets with improved vitality effectivity. The business leaders had been the Bitmain Antminer S19 Pro and MicroBT Whatsminer M30S+ sequence. Publicly listed producer Canaan additionally launched new miners such because the AvalonMiner 1166 Pro and the liquid-cooled A1066I unit.

The new miners provided vital effectivity good points, primarily on account of their extra superior chip lithography. The S19 Pro makes use of 7-nanometer chips, whereas the M30S+ makes use of 8-nm lithography. The measurement signifies the gap between two ends of a transistor on a chip — at these values, it’s only a dozen atoms large. Lowering the gap helps improve computing efficiency and scale back energy consumption.


Jiang defined that the Bitcoin mining business is at present experimenting with TSMC’s 5-nm course of, whereas the chip producer is already researching 3-nm lithography. A discount from 5 to three nm could be a significant achievement for the computing business, as it might enable to pack roughly 60% extra transistors in the identical chip. But in line with Jiang, the most recent developments in chip know-how are hitting some basic bodily limits:

“The smaller the nanometer [distance], the less significant the increase in power efficiency, because when the nanometers decrease to a certain level, it will involve quantum problems. […] The quantum [tunneling] effect will cause electrons to jump around between different diodes, therefore, the electron leakage ratio will rise.”

The sensible result’s that newer chips can have higher computing efficiency however are unlikely to hold as sturdy enhancements in vitality effectivity, Jiang mentioned. “Bitcoin mining actually does not require high computing; it requires a better power efficiency — that is, the less power you consume with the same hash power, the better,” he added.

Other kinds of efficiency enhancements like liquid cooling will be helpful however don’t radically alter the miner’s effectivity. Jiang defined:

“Liquid cooling can only improve the mining efficiency by a certain degree. For example, a machine with 100 watts per terahash power efficiency, if you use an air-cooling system, after a period of time, due to dust or inappropriate cleaning, the machine’s power efficiency will decrease to 105 watts-terahash, while the liquid cooling system can allow you to increase the efficiency to about 95 watts-terahash. That’s only a 5% improvement — this difference is not significant.”

Is now a very good time to enter the mining business?

The vastly inflated income for miners comes as the worldwide electronics business is below intense stress. Normally, new gadgets would rapidly fill the hole and produce down the common income to imply values. The present chip shortages imply that this end result might take longer than normal to happen, however current gadgets are nonetheless being offered at a significant-enough premium to make potential patrons think about their actions twice. For instance, the S19 Pro at present has a return-on-investment interval of eight months primarily based on the electrical energy worth of $0.04 per kilowatt-hour. However, if its income had been to break down to the still-high ranges of December 2020, the miner would want to work for as much as 40 months to pay itself again.

In the three years that the miner may doubtlessly require to show a revenue, new gadgets may make the S19 partially out of date, prolonging the payback interval even additional. Still, in line with Jiang, the mining business might be heading for consolidation round state-of-the-art gadgets, with solely marginal enhancements over earlier generations. This would enhance the lifetime expectation for mining gadgets, making certain the steadiness of any funding made now or sooner or later. ASICs have already stabilized to a major extent, because the five-year-old Bitmain S9, for instance, solely grew to become utterly unprofitable after the 2020 halving however is now as soon as once more producing an inexpensive revenue of $3 per day, assuming electrical energy costs of $0.04 kWh.

“Unless you buy a very expensive mine at the peak of the bull market, it’s hard not to make profits,” Jiang concluded.

Are miners higher hodlers?

Jiang believes that the economics of mining makes it a superior technique to accumulate Bitcoin and maintain it by the whole lot of a rally. According to him, most Bitcoin miners stored their BTC all the best way to $20,000 in 2017, whereas common holders had a a lot decrease likelihood of holding by to the highest.


Jiang didn’t want to elaborate on the information supply of this conviction, which matches towards the overall knowledge that miners instantly promote the Bitcoin they mine. An analysis by Coinmetrics exhibits a nuanced image: Miners maintain a really significant slice of the Bitcoin provide, most of which was acquired within the early years of its existence. Partially confirming Jiang’s thesis, through the 2017 bull market, the miners appear to have accelerated their promoting solely round October, carefully timing the highest on the time.

A large improve within the miners’ Bitcoin holdings will be noticed towards the tip of 2019, suggesting that they started holding a bigger proportion of their proceeds. Still, the relative prevalence of miner holdings has been on a gentle decline all through Bitcoin’s historical past, indicating that many of the BTC they mine finally ends up offered on the broader market.

According to Jiang, although, miners will be much less influenced by loss aversion: the pure human tendency of avoiding extra worthwhile outcomes if additionally they carry greater danger.

He defined that the mechanics of mining make it psychologically simpler to carry by unstable markets:

“The first reason is that the mining machine is like a golden goose that can lay golden eggs in the bull market, so no miners would sell this golden goose […] The second reason is the process of selling mining machines is much more complicated than selling Bitcoin on exchanges.”

The case for buying Bitcoin publicity by mining stays nuanced. In most instances, breaking even on the funding requires ready for a yr or extra, relying on the preliminary entry level. Compared to purchasing Bitcoin outright, miners might lose out on main worth good points instantly after, however that is compensated by greater resilience throughout market downturns. The mining machine will pay itself off even when the value of Bitcoin takes exceedingly lengthy to return to its earlier highs.

Bitcoin mining is not only for professionals

Being a profitable miner is just like working a enterprise. After an preliminary setup price, the enterprise can flip a gentle revenue however requires upkeep and oversight. Not everybody has entry to the circumstances required to arrange a profitable mining farm, crucial of which is the placement — low cost electrical energy is a should for miners.

It remains to be attainable to buy ASICs from retail outlets and mine at dwelling, supplied that the house electrical energy worth is beneath $0.10 kWh. Such figures can normally be discovered solely in creating international locations which have ample pure assets.

Some mining swimming pools and firms provide quite a lot of methods for others to make use of their amenities — for a charge. The major strategies are colocation and cloud mining, which differ considerably when it comes to their construction. Colocation providers merely cost a charge for electrical energy and upkeep, whereas the gadgets are supplied by the consumer. Cloud mining providers are, basically, a lot completely different and riskier than self-hosted mining. Usually, the contracts final a predefined period of time and carry vital upkeep prices. This provides a restricted period of time to recoup the preliminary funding, making it extra of a wager on the value of crypto with considerably restricted upside. Overall, the opacity of the mechanism typically raises questions from regulators in regards to the legitimacy of some cloud mining operations.

Jiang’s firm recently launched a service known as “joint mining,” which modifications the enterprise mannequin of cloud mining to make it nearer to actual mining:


“For example, a customer spends 10,000 yuan [$1,540] to buy a mining machine to dig a mine. When he receives 10,000 yuan of Bitcoin from the mining machine, after his investment returns the capital, we start to charge service fees. The Bitcoin produced afterwards is net profit. We collect 20% of the net profit — that is, 20% of the Bitcoin produced later. If the customer doesn’t get back the money in the end, we won’t charge.”

The BTC.prime platform is thus nearer to an assisted colocation service than classical cloud mining, with the corporate additionally permitting purchasers to “withdraw” their miners and have them delivered to a vacation spot of their selecting.

As the Bitcoin mining business stabilizes and matures, the businesses concerned within the enterprise might grow to be essential diversification instruments for traders. The distinctive danger and reward profile of mining is just like gold mining corporations, that are historically included in lots of exchange-traded funds for gold publicity. Jiang concluded with one other parallel between Bitcoin and gold:

“The bull market of Bitcoin has increased more than I expected, so I expect that the top of this bull market may not be $100,000 as I expected, but may reach $200,000 or even $300,000, making Bitcoin exceed the total market value of gold.”
