We use batch processing for all mining machine orders, and the quantity of each batch is very limited. Even if the same type of mining machine, different batches of mining machine prices are not the same. They’re selling fast. Given the highly variable market and demand, the prices of stock miners may vary from day to day. Therefore, so there is a possibility that by the time we receive your payment, the price of the mining machine has gone up and we need to refund your order.
