3.2 Introduction to miner related costs
The main costs of an order can be divided into miner fees, electricity fees, and operation and maintenance fees. According to product types, miner fees can be divided into miner Lease fees, miner purchase fees, and miner deposits.
Miner Cost: The miner rental fee is the miner rental fee/miner purchase fee, and its pricing will be adjusted according to market changes. The actual purchase price is subject to the user's payment, and MCLOUDS will not compensate for the price difference. In addition to the miner cost, in order to ensure the stable operation of the miner in the later stage, the user also needs to pay the corresponding electricity fee and operation and maintenance fee for the order.
Electricity Cost: The miner in operation requires the user to charge and pay the electricity fee in time. The electricity fee is calculated according to the rated power of the purchased miner and the electricity price indicated in the order. The user can choose to prepay the electricity fee or deduct with income. If the user's prepaid electricity bill is exhausted, MCLOUDS will automatically deduct it from the mining revenue; if the revenue is not enough to pay the electricity bill, MCLOUDS will temporarily shut down the affected miner and notify the user through the contact information reserved by the user.
Operation and maintenance Cost: MCLOUDS will charge operation and maintenance fees for all miners, and provide miner entrusted management services, including miner transportation, site support, daily monitoring, miner maintenance, repair, hashrate guarantee, etc. The operation and maintenance fee will be deducted from the daily hashrate income.

4.4 Why is my mining output dropping?
Mining output is not only related to mining resources such as miners and mining pools, but also related to the total network hashrate, difficulty and other states. In addition to the fluctuation of hardware hashrate, the proportion of miner hashrate and mining pool hashrate will affect the proportion of mining output that users can allocate, and the hashrate ratio will always be in a state of change; the total network hashrate and network difficulty It will affect the overall mining output, and the network difficulty is frequently adjusted according to the hashrate of the entire network, resulting in the user’s hashrate income always fluctuating, some of which will cause the mining output to decline.

4.5 Situations that could cause earnings to fluctuate:
Since mining is affected by various factors such as miners, mining farms, mining pools, the hashrate of the entire network, and difficulty, it is normal for income to fluctuate. MCLOUDS does not promise to guarantee stable income. Among the leased products, MCLOUDS guarantees that the miner selected by the user will maintain uninterrupted operation, and immediately switches to other miners of the same type after the failure of the miner to protect the user's income; among the products with permanent property rights, MCLOUDS guarantees the operation and maintenance of the miner selected by the user, During the operation and maintenance service period, the miner will be repaired free of charge, and the mining electricity fee will not be charged during the maintenance period.MCLOUDS is not responsible for the losses caused by the following uncontrollable risks: objective events that cannot be foreseen, unavoidable or insurmountable, including natural disasters such as floods, volcanic eruptions, earthquakes, landslides, fires, and those that have been assessed by government departments as rare in a century or above Storms, severe weather, etc., government actions and government orders, city-level grid power supply accidents, and social abnormal events such as wars, strikes, turmoil and other normal business risks other than any risks.

5. Price Adjustment Rules

5.1 Miner price adjustment rules
Miner pricing is affected by factors such as the mining recovery cycle, production capacity, and currency price expectations. If coin price is expected to appreciate strongly, but the production capacity of miners does not increase on a large scale, the price of miners will increase significantly. Similarly, When the medium and long-term price of the currency price is expected to decline, the price of the miner may also decrease. The price of miners sold by MCLOUDS will be adjusted according to the market price of miners.

5.2 Electricity and management fee adjustment rules
The electricity fee and management fee will be displayed in plain text before the user pays. The electricity fee will be deducted on a daily basis according to the rated power of the mining machine, and the management fee will be automatically deducted from the mining revenue. If force majeure factors occur (such as government actions and government orders to increase regional electricity prices, urban and above-level power grid power supply accidents lead to increased power transmission costs, etc.), resulting in an increase in the electricity price, after the system adjusts the electricity price, the user will pay the electricity fee at the new electricity price.
