In order to be able to mine crypto-currencies, special hardware such as graphic cards, rigs, ASIC, FPGA and other mining equipments should be used. The computer and the room need adaptations for heat and air flow.

What hardware should be used to mine ?
Basically, many chips are able to help for mining but in a general case, all old chips are not efficient enough and using old mining equipment can lead to a big electricity bill and not enough coins to pay it. We strongly recommand to NOT mine using a CPU or old GPU for mining. In addition, a good airflow is needed to keep your hardware at low temperature for long term use.

Graphic cards
Both nVidia and AMD/ATI graphic cards can be used for mining. Please keep in mind that the computer need to be adapted for mining: a proper air cooling system should be installed and a power supply strong enough should be chosen. A gaming computer with 2 GPU's can be used for mining as a hobby or to test mining but if you want to add more GPU's, you should consider to adapt both the power supply and the air cooling system. A "rig" is a special computer case adapted for mining that allows a good airflow for all the components, have a good distance between GPU to have enough air flow in between and have enough room to have several graphic cards in it.

AMD cards such as RX470, RX570, RX480 and RX580 are suited for mining.

nVidia cards such as GTX 1060, GTX 1070, GTX 1080 and GTX 1080 Ti are suited for mining. nVidia cards are able to have good performances on much more algorithms than AMD cards so whatever if nVidia cards are more expensive than AMD, nVidia can mine more different crypto-currencies than AMD. But on the other hand, AMD cards are chaeper and can be have a better return on investment.

Some companies sell professionnal rigs with additionnal temperature sensors, some with AMD and other with nVidia cards.

Some professionnal miners use industrial hardware dedicated to few algorithms. As this kind of hardware is dedicated to one (or several) algorithm, when ASIC or FPGA appear on a algorithm that was ASIC resilient, the difficulty raise on all coins of the algorithm. Some people suggest that it may be possible to detect the new generations of ASIC/FPGA compatible for new algorithms by analysing difficulty charts.
