Optimal Mining Power

First of all, thank you for your interest and support to Best World Miner. In order to avoid misunderstandings in the process of purchasing a miner, please read all the following notes carefully before placing your order. Thank you very much for your understanding!

1 – Regarding the specific dynamic of the miners market, there is a possibility that the miner’s price has changed when we receive your payment and we might need to refund your order.

We use a batch process for all the miners orders, and that we have each batch at quite limited quantities. The price of different batches of miners is different even though it’s the same model of miner. They are selling pretty fast.

Regarding the highly variable and demanded market, the price could be different every day for in stock miners. So there is a possibility that the miner’s price has gone up when we receive your payment and we need to refund you for the order.

2 – About inventory miners

The inventory miner delivery date will be 3-7 working days. Once we receive your order, we will immediately notify our technical center staff to test the machine you have ordered to ensure that it is running well.

We will ship the machine to you only after we make sure that all the performance of the machine is fine. Then, we will deliver the machine to our freight forwarder for shipping. We will update the tracking number on the website and you will receive an email for details.
