Customer FAQs
How long does it take to mine a Bitcoin?
The mining machine is calculated based on its daily output revenue, the time required to recover the investment cost of the mining machine, and the return rate, which is more valuable. There are many factors to consider when mining a coin, and it cannot be simply stated in one sentence!
Can I pick up the machine myself?
Yes, we offer self-pickup options. We have warehouses in Hong Kong, and the United States, so you can choose the nearest location based on your needs. Alternatively, we can also ship the machine to your forwarder's address.
Are miners purchased through you new?
Yes, we only sell brand new, factory-sealed miners. Apexto Team purchases equipment directly from the factory, ensuring all products are new and unused.
Typically, miners are shipped directly from the warehouse without opening the packaging. We only open the packaging for testing if requested by the customer before shipment.
