I don't believe it, you haven't thought about mining bitcoins yourself.

When I first heard about Bitcoin, my first question was "how did Bitcoin come about", and then I thought about "what is it for" and "how much is it".

Now we all know that Bitcoin is generated and confirmed when miners compete to solve problems (calculate Hash) on the block. This process is commonly known as "mining".

Over the years, mining has undergone an evolution from the early "mining with a personal computer (CPU, graphics card)" to the current "mining with a dedicated mining machine (chip)".

The market also began to concentrate a few years ago and entered the stage of "monopoly by several major mine owners".

Most of the "mining novices" who enter the market now join the mine through mining pools (which can be understood as crowdsourcing mining with software services), and a small number of people hold resources and "package to support" high-performance mines in low electricity prices. unit. Some people see that the bonus period for mining mainstream currencies (Bitcoin, Ethereum) has passed, and they start to specialize in "new small currencies".

Wingbit E9.3

More "mining" history and current situation will be released in-depth articles in the near future for further introduction and interpretation, so I won't go into details here.

Today, we mainly discuss what core indicators should be paid attention to when choosing a Bitcoin mining machine if an individual wants to participate in Bitcoin mining.

Odaily, together with strategic partner Whale Research Institute, launched a Bitcoin mining machine "purchasing guide" for beginners, enjoy~

Some people see that the bonus period for mining mainstream currencies (Bitcoin, Ethereum) has passed, and they start to specialize in "new small currencies".Theoretically, the number of bitcoins obtained by the mining machine = (the number of bitcoins mined on the day / the computing power of the entire network) * the computing power of the mining machine。

• Payback period = mining machine price / (daily income - electricity fee)

• Daily income = theoretically the number of bitcoins obtained by mining machines * real-time price of bitcoins

• Theoretically, the number of bitcoins obtained by the mining machine = (the number of bitcoins mined on the day / the computing power of the entire network) * the computing power of the mining machine

Based on the selling price and currency price on June 4, 2018, and the electricity cost of 0.3 yuan/kWh, among the nine mainstream Bitcoin mining machines, only the ones that can pay back their costs within one year are:

• Ant mining machine S9i, 262 days;

• Antminer T9+, 290 days;

• Wingbit E9.3, 345 days.

Of course, the final "payback period" is floating, and the life of the mining machine and the mining software share must also be considered comprehensively...

Don't forget that the price of mining machines is not static. For example, "Ant Mining Machine Sales" announced yesterday that the price of the Ant Mining Machine Z9 Mini has been adjusted to RMB 5,900 per unit, which is nearly half of the price of RMB 11,000 per unit when it went on sale on May 16.

From the supply side, the mining machine market may not be a long-term monopoly. this week,Japanese internet giant GMO announced the first 7nm bitcoin mining machine B2. Under the power consumption of 1950W, the B2 mining machine can achieve a computing power of 24TH/s (computing power consumption ratio is 1TH/81W), far exceeding the 13.5TH/s of the ant mining machine S9i. However, the retail price of the B2 mining machine is US$1,999, which is much higher than the 5,600 yuan (about US$877) of the ant mining machine S9i. By the way, GMO mining machines are more used in internal mines, not for external sales.

Based on the selling price and currency price on June 4, 2018, and the electricity cost of 0.3 yuan/kWh, among the nine mainstream Bitcoin mining machines, only the ones that can pay back their costs within one year are:
