In a blink of an eye, it is the month of year-end summary again.
Oxford Dictionaries, one of the most comprehensive and authoritative English dictionaries in contemporary times, publishes its annual vocabulary every year, but this year it has unprecedentedly expressed that it cannot choose a suitable word to describe 2020. From the new crown epidemic at the beginning of the year to the bushfires in Australia, from the "Black Lives Matter" anti-racial demonstrations in the United States to the US election, there are too many things worth remembering that happened in 2020.
In the blockchain industry, there have also been many major events in 2020 that are worthy of careful review in the future. In today’s article, Mining will first lead you to take stock of 10 things that have had a relatively large impact on the group of miners.

01 312 plunge
Under the combined effect of multiple factors such as the new crown epidemic, high leverage, and the technical death cycle of the Bitmex exchange, on March 12th BTC suddenly plummeted from 7934USDT to below 5000USDT, and the currency price continued to drop the next day, falling to a minimum of 3782.13USDT.
The plunge of BTC price has dragged down the entire encryption market. In just a few days, the market value of the entire cryptocurrency market has evaporated by more than 100 billion US dollars.
The biggest inspiration for miners from the 3.12 plunge is to be cautious about using leverage on the market. Borrowing money to mine can indeed make money and coins, but the money must come from off-site. Because of the black swan market of 312, even with double the leverage on the market, it can explode cleanly.

02 Release of Antminer S19 mining machine
The mining machine is like a hen that lays golden eggs, continuously bringing "after-sleep income" to our miners.
This year, the most noteworthy Bitcoin mining machine is the Antminer S19 series developed by Bitmain. The Antminer S19 series can be divided into two models: S19 and S19 Pro. Among them, the computing power of the S19 mining machine is 95T, and the energy efficiency ratio is 34.21W/T; the computing power of the S19 Pro mining machine is 110T, and the energy efficiency ratio reaches 29.55 W/T, which is far ahead of competitors.Due to the slump of 3.12 and the sluggish currency price, Bitmain delayed for a week before announcing the price of the Antminer S19 mining machine. Held at Zhikuang UniversityB.TOP press conference and the first interview with miners in the world
In ", Jiang Zhuoer, the founder of Leibbit, analyzed:
The first batch of S19-95T mining machines are the futures in May, and the price is 15,295 yuan (200 yuan cheaper than the official website) when it is launched on the B.TOP platform under Lebbit. Looking back now, if we had bought the S19 mining machine in BIDHU at that time, it would have been a very successful mining investment. The production capacity of mining machines is generally insufficient this year, and it is hard to find one. Bitmain’s S19 futures mining machines have been sold until August 2021, and the price for major customers is as high as 13,770 yuan.

03 Mining output halved
On April 8 this year, BCH took the lead in ushering in the halving of mining output, and the block reward was reduced from the previous 12.5BCH to 6.25BCH. During the period when BCH mining output has been halved but BTC has not yet been halved, as previously popularized by Zhikuang University, BCH has not entered a death spiral.
On May 12, Beijing time, the Bitcoin block reward was also halved as scheduled. After the halving, Bitcoin’s annual inflation rate dropped from the previous 3.7% to 1.8%, which is lower than the 2% inflation target designed by most central banks in the world for fiat currencies.
In addition to BTC, BCH, and BSV, many small mining coins have also experienced production reductions this year: BEAM, ETC, DASH, XZC, ZEC, ZEN, Sero, etc.

04 Park electricity
This year, the term "park electricity" has entered the field of vision of many miners. The power in the park refers to the power in the Sichuan Hydropower Consumption Industry Demonstration Zone, because this power is consumed in the government-planned industrial park, commonly known as park power.
This year is the first year for Sichuan Province to implement park electricity. Compared with direct power supply, park power has the following advantages:
1. The power of the park comes from the national grid, which has better stability.
2. The price of electricity in the park is transparent, and the cost structure is also very clear and transparent.
3. The electricity in the park is safer.
4. Power in the park means that the site is safer and the traffic is more convenient.The owner of the mine talked about all aspects of the park's electricity》。

05 DeFi Liquidity Mining
At the end of May and the beginning of June this year, the decentralized lending platform Compound fired the first shot of DeFi liquidity mining, and the price of its token COMP rose to a maximum of $372.27. The success of Compound has injected new vitality into DeFi, and more and more projects have launched similar incentive mechanisms for liquidity mining.
However, after a short period of madness, the bubble burst, and the prices of many tokens plummeted, even heading straight to zero. In the end, we found that we "classical miners" had the last laugh, because the popularity of DeFi caused the congestion of the Ethereum network, and the price of Gas soared. During that time, the income of our graphics card mining machines was more than three times that of usual.

06 Filecoin mainnet launch
After more than two months of development, the current effective computing power of Filecoin's entire network has reached 1.476EiB, and the number of active miners has reached 836.

07 Card breaking operation
Affected by the card breaking action, the difficulty of withdrawing gold has increased a lot, and miners have to pay electricity bills every month, which is greatly affected. According to official reports, there is no time limit for this card-breaking operation until the passive situation where two cards are flooded and a large number of two cards are used for crimes is completely changed.

08 BCH forked again
On November 13, 2018, the disagreement on the upper limit of the BCH block size led to the fork of BCH, which forked BSV to engage in "unlimited blocks".
At the time of writing this article, the price of BCH is 310USDT, and the price of the forked BCHA is 19.5USDT, which is less than one-tenth of the price of BCH. For miners, it is good to receive candy BCHA for free after the fork.

09 Ethereum 2.0 and 4G graphics card
On December 1st, the beacon chain of Ethereum 2.0 was successfully launched. As of writing, in the Ethereum 2.0 contract deposit address, the accumulated ETH of staking exceeds 1.79 million pieces, and the current annualized rate of return of staking is about 11.5%.
For miners, the biggest impact of Ethereum 2.0 is its PoS consensus mechanism. Once the current Ethereum PoW chain is merged into the PoS chain, Ethereum mining machines can no longer mine ETH. However, miners don’t need to worry yet, because according to the estimates of industry veterans, Ethereum can still be mined for another one and a half to two years.Even though the beacon chain is now online, it is still a good time to enter the Ethereum mining market. For the specific logic, please refer to the previous tweet of Zhikuang University.》。
ETH 2.0 is here, can I still buy mining machines to mine ETH?
After the 4G graphics card mining machine is eliminated, how much the entire network computing power of Ethereum will fluctuate is worthy of our miners' attention.
10 Bitcoin hits all-time high
exist"exist"Where is the current bull market cycle & the upcoming skyrocketing mainstream coins
"In the article, Jiang Zhuoer, the founder of Leibit Mining Pool, mentioned that only when BTC breaks 20,000 can it really break through the previous high, and there will be a lot of news and traffic. On December 16 this year, Bitcoin successfully broke through the $20,000 mark. Subsequently, Bitcoin broke through 21,000, 22,000, 23,000, and 24,000 US dollars one after another. As of writing, Bitcoin reached a peak of 24,295 US dollars.
The blockchain market is often the hairtail market. What is worse than not being able to eat fish is that a hairtail only eats a fish head. Of course, historically speaking, it is a pity that most people can't hold the currency, and they all sold the currency early at some point in the bull market. Only miners, and most of them, can eat the bull market from beginning to end. The reason is simple: you can’t help but want to sell the coins that have increased by 10 times in your hand, but the hen that keeps laying golden eggs in your hand (miner) machine), you definitely wouldn't want to sell it.
