For the needs of a client from Serbia, we visited a workshop from Shenzhen with which we have a long-term cooperation in the procurement of used antminers and used ASIC machines.
Within the workshop, there is also a department where buyers or agents can check the correctness of the goods themselves before buying, and that is why we visited this shop.
Since we are regular customers of their ASIC machines, they allowed us to photograph and record parts of the factory and show them to you. We want to show you what the inside of a factory looks like, where old machines for mining bitcoin, ethereum and other virtual currencies are repaired.

The topic is very interesting for us since China is the largest producer of solar panels and the leader in the use of renewable energy sources obtained from solar panels.
