The stability of the connection, the convenience of working with the equipment and the possibility of remote control are more important than the speed of the Internet for mining. However, if it is possible to choose a channel from several options, then what is the minimum Internet speed needed for mining and does Bitcoin mining slow down the Internet speed? In this article, we will consider the necessary parameters of the Internet when mining cryptocurrency.
Bandwidth per second and ping
The bandwidth of the channel per unit of time, or, as it is more commonly called, the Internet speed, is measured in megabits or kilobits per second. The speed of incoming information can differ significantly from the speed of outgoing. You can measure the real speed on any free service.
Most often, in their standard packages, providers provide a higher “input” speed (for downloading information from the Internet) and a lower “output” speed (for sending). This is quite consistent with the volume of mining traffic: incoming traffic is usually 6-7 times more outgoing.
To begin with, it is necessary to clarify that the Internet speed is usually calculated in megabits (Mbps), and not megabytes (Mb), while 1 Mb = 8 Mbps. Most providers’ standard packages currently offer monthly rates of 50 Mbps and 100 Mbps.
The speed sufficient for any single miner is 10 Kbps. This indicator is suitable for both ASIC hardware and GPU. For example, a GPU farm of 5 video cards, together with the system traffic per day, receives and receives approximately 15 MB = 120 MBit. Let’s make a simple calculation. Since there are 86,400 seconds in a day, divide 120 Mbit by 86,400 seconds. 0.001 Mbps will come out. We see that even 2-3 Mbit / s packets will be enough for cryptocurrency mining.
This “default” speed is now provided by almost all providers, including mobile operators, so when planning mining, this parameter as a separate accounting parameter may not even be considered, because a higher speed will not increase mining efficiency. But testing the speed of the Internet connection shows another indicator – Ping.
Ping is the period for which data is exchanged between the provider’s equipment and the user’s device. Ping is measured in milliseconds (ms). The lower this figure (that is, the fewer milliseconds it takes to exchange packets), the better. It is believed that you can mine without problems with a ping of 90 milliseconds (or less). The optimal value is 15 msec.
But, in addition to the time of exchanging packets between the devices of the provider and the user, when mining through a pool, one should also take into account the time of exchanging data packets between the provider’s server and the pool server. To calculate this period, you need to: Simultaneously press the Windows logo key and the “R” key to open the control panel and enter “cmd” in the field.
When the Windows console starts, enter the word “ping” and then after a space enter the address of the pool server.
The results that appear will show the maximum and minimum ping values, as well as the average. In this case, it is 60 ms.
What ping is needed for mining? The best indicator is a speed of 10-15 ms. A sufficient speed will be 70 ms. Indicators above this value can negatively affect the final results, although even with a response speed of 200 ms, the equipment can operate with an efficiency of 100%.
More important requirements than speed are connection stability and ping pools.
Internet for mining: other connection parameters
In addition to the speed and time of packet exchange, there is also a parameter for the amount of information transmitted per unit of time – traffic. Most miners in connected Internet packages have an unlimited tariff, but sometimes it is limited by the number of megabytes per day or month. This is important because the stability of the connection is important for mining, and if the megabytes are depleted, the connection will be interrupted.
In an approximate calculation for a mining farm of 5 video cards, you need about 120 Mbit with a speed of 0.001 Mbit / s. (with round-the-clock work without shutdown). With a stable Internet connection speed of 3 Mbps. should be enough. But the actual traffic also depends on the type of video card and the hardware manufacturer.
The type of Internet connection for mining does not matter. It can be wired (fiber optic, telephone cable, twisted pair, coaxial) or wireless (Wi-Fi, mobile Internet). Often, the cable is separated from the router and fed to each computer or farm separately. When choosing a Wi-Fi connection, you should separately take care of protecting the farm from hacker hacking.
Thus, any Internet connection is suitable for Bitcoin mining, since it is the speed that does not matter much here. The main thing is that the signal is stable and its flow is not interrupted. Therefore, even a very fast Internet, but constantly interrupted due to technical problems or network congestion, will be much worse than a very slow but stable connection. Since, if the connection is constantly interrupted, you will have to constantly be near the equipment and restart the program. To prevent this from happening, choose a good, reliable provider if you plan to start mining BTC or other cryptocurrency.
