Bitcoin Solo Mining "Lottery Machine" Review

Recently, a kind of micro-computing mining machine called Bitcoin "lottery machine" has suddenly become popular in WeChat Moments. Why is it called "lottery machine"? We can explain it from two aspects:

1. Awarding Mode

As we all know, except for the instant lottery draw model of scratch tickets, all other lotteries are drawn regularly. The block generation of Bitcoin mining is similar to this regular draw model. The Bitcoin mining algorithm will regularly adjust the difficulty of computing power according to the different computing power of the entire network, making the theoretical block generation time of Bitcoin close to 10 minutes, that is, a prize is drawn every 10 minutes, and 144 prizes are drawn a day.

2. Probability of Winning

Take the Double Color Ball lottery as an example. The probability of winning the first prize is one in tens of millions. Although the probability of winning is low, some people still enjoy it. The probability of winning the Bitcoin "lottery machine" is also very low, but it only has one first prize. As long as the block is exploded, 6.5 BTC will be credited to the account. Calculated at the current price of 34,000 US dollars, it is equivalent to about 1.6 million RMB.

Now I want to show you a Bitcoin "lottery machine" (JDHX WiFi ASIC MINER) that I just got. Let me show you its geeky appearance first.

Looking at this open design, it turns out that the master only cares about performance and never cares about appearance. But what surprised me most was that a small screen was integrated into the 10cm X 5.5cm development board, which is much more user-friendly than a high-power mining machine.

Next, I will show you how to configure this small mining machine. Due to its small size, it does not have an integrated network cable interface. We need to configure it in a WiFi environment. Mobile phones and computers with wireless functions can be used for configuration.

1. First, find the WiFi that starts with Bitaxe and connect directly without a password. After the connection is completed, click the browser and the configuration interface will automatically pop up.

2. Configure WiFi name and WiFi password

3. Configure the mining pool address 8.210.2.17 and the mining pool port number 6189 (this is the officially recommended solo mining pool, you can change to solo/pps mining pool according to your own needs)

4. Configure the wallet address 1PtPsyXb4dqhGzmHV7J3fzccg8zqr4B23F.wabi (the part before the decimal point is the wallet address, and the part after is the miner name, modify it according to your own address)

5. Save and restart.

6. The following picture is a picture tutorial

After the mining machine has been running stably for a day, log in to the official recommended mining pool homepage https://web.public-pool.io/#/, enter the wallet address and miner name, and you can see the mining machine's computing power. As can be seen from the figure below, the average computing power of the mining machine is about 300G, of course, there is a more powerful way to express it 0.3T. But to be honest, this computing power is already very good for a single-chip mining machine. The 2-hour computing power curve fluctuates smoothly, indicating that the connection stability of the mining machine is still very strong.

Since the mining machine is an open design, the editor can avoid the trouble of disassembling the machine and not being able to put it back together. However, the editor still measured the operating temperature and operating noise for everyone. In order to show the operating temperature more intuitively, the editor also asked the manufacturer for an infrared remote sensing picture.

Finally, let's take a look at the actual data of this mining machine

Size: 10cm x 5.5cm

Computing power: 300G+

Power: 15w

Chip temperature: 52.9 degrees

Noise level: 49.4 dB

Summary: As the computing power of mining machines becomes more and more competitive, the highest computing power of a single machine has reached 390T. The emergence of a reverse inward-rolling mining machine provides small and scattered users with the opportunity to experience mining. Although the probability of winning is very low, there is still hope. This kind of mining machine does not need to consider power consumption and noise, and it has direct WiFi connection, so it is stress-free whether at home or in the office. Some competing products have also appeared in the market, but the computing power parameter is only 55k, which is nearly 5.5 million times the gap with 300G. It is really a bit like the difference between catching a needle in a haystack and catching a steel plate in a haystack. What do you think, would you buy such a geek toy?
