ASIK efficiency
The cost of energy and the hash rate that you can achieve on a specific ASIK directly affect the profit and the speed of the payback of the device. Therefore, when choosing ASIK, you should carefully study the “combinations” of acceleration profiles and power consumption. It is recommended to choose the most profitable model in this regard.
Also, having bought a new ASIK, improve it with custom firmware (this is almost an obligatory step, because today it is very difficult to profitably mine without using firmware). Using it, you can achieve one of the following “scenarios”:
- Increasing the hash rate (while the power consumption remains at the current level)
- Maximum increase in hash rate (while energy consumption also increases)
- Reducing the current level of power consumption (while the hash rate does not change).
An example with Antminer T17 will explain the efficiency and profitability of the firmware more clearly. The stock firmware of this ASIK allows you to achieve a hash rate of 40 Tx / s, while the device consumes 2200 watts. With the Hiveon ASIC firmware, the Antminer T17 consumes 1816 W (at the same hash rate), and the maximum possible hash rate is 56 Tx / s (on a standard power supply). Moreover, the firmware allows you to extend the service life of the ASIK.
Easy to control ASIK
The easier it is for you to manage ASIK, the more attention you can pay to the mining process. The Hive OS monitoring and control system can greatly simplify the task - with its help, you can control ASIK remotely, monitor their performance, and so on. Therefore, when choosing a new device, pay attention to those ASIK models that are compatible with it. A complete list of supported models can be found here .
Spare parts availability
Choosing ASIK, find out if you can buy spare parts in your city or country. And if so, what is their cost? Choose those ASIKs for which you can get spare parts as soon as possible. This way you will avoid serious pauses in the mining process and loss of income.
In addition, the following two factors should be considered:
- . , , . , , Bitmain, , Innosilicon . 17- Bitmain .
- Bitmain.
If you are looking to purchase a large number of devices, their price may be the most influential factor.
Be sure to compare prices from multiple vendors. Some of these may add value on purpose and you may overpay. But by checking the offers of other suppliers, you will avoid this situation.
Also, do not purchase new ASIKs immediately after their release. Wait a little - over time, their price will decrease slightly, and you will also have the opportunity to read reviews and decide if these devices are worth your investment.
It is also worth finding out how much electricity ASIK consumes on terahash. For example, some devices require 1.6 kW of power, while others require 6 kW. As a result, ASIK, which consumes 6 kW of energy, will cost much more, because you will spend a substantial part of your profits on paying your electricity bills.
Device warranty
Warranty terms are another factor worth paying attention to:
- What is the guarantee period for your potential ASIK? Obviously, the longer the warranty is valid, the better and easier it is for you.
