Frequently Asked Questions

How Hosted ASICs Marketplace Works
An ASIC miner is a specialized device designed exclusively for mining. Compared to GPU mining, miners ASIC deliver significantly higher efficiency, which has already made ASIC mining the industry standard for BTC extraction, especially at an industrial scale.
A reliable supplier of ASIC mining hardware operates within a legal framework and often has direct agreements with manufacturers such as Bitmain, MicroBT, and Goldshell. The origin of the equipment can always be verified, and serial numbers match the manufacturer's database. ECOS has been selling bitcoin miners for over eight years and guarantees verified specifications and transparent purchase conditions for anyone looking to buy ASIC miner solutions safely.
When selecting an ASIC mining machine, it is important to consider hashrate, power consumption, and payback period. On our platform, you can compare different ASIC miners by key parameters and choose the most suitable option. You can also browse the marketplace and select bitcoin mining machine offers based on your preferred criteria.
On the ECOS marketplace, users can purchase new and previously used ASIC miners at below-market ASIC prices, start ASIC mining, and later resell their equipment without leaving the platform. The marketplace provides full transparency, showing electricity costs, hosting fees, and service conditions in advance, along with a clear total cost of ownership for each bitcoin mining machine.
On our website, you can purchase new bitcoin mining equipment and place it in our data center, ensuring low electricity costs and stable returns without technical complexity. Marketplace purchases offer the same ASIC mining hardware at a lower ASIC price, but these units have already been in operation.
Yes. We sell only verified used ASIC miners with confirmed specifications and documented operating history.
