What is Bitcoin Lottery Mining?
>Bitcoin lottery mining is a solo mining approach where individual miners or small-scale operations compete to discover a valid block on the Bitcoin network. It's called "lottery" mining because it resembles playing a lottery—chances of winning are slim, but the potential payoff is significant. Unlike pool mining, where miners combine their computing power and split the rewards, lottery miners go it alone in hopes of claiming the full block reward for themselves.
>This strategy is deeply tied to Bitcoin’s proof-of-work consensus mechanism. Approximately every 10 minutes, a new block is added to the blockchain. Miners worldwide race to solve a complex mathematical puzzle, and the first to solve it earns the right to add the block and receive the full reward. In pool mining, this reward is divided among all contributors based on their share of computational power. In lottery mining, however, the entire reward goes to the solo miner who cracks the puzzle first—making it a high-risk, high-reward endeavor.

We can arrange to send you a replacement casing with the correct specifications. Kindly confirm whether you need a replacement and provide your shipping address.
>Q3: Why does the product only have one Micro USB port instead of the two ports mentioned in the description?
A3: We sincerely apologize for the confusion caused by the unclear product description. Upon verification, the port configuration of this batch of products is as described. This will not affect the product's functionality. If you have any concerns or are unsatisfied, please contact our after-sales service, and we will provide you with an appropriate solution.
>Q4: I didn't receive the instruction manual. How can I install or connect the device?
A4: To facilitate customer use, we have recorded installation and connection videos. Please contact us to obtain the video links. If the provided links have expired, please reach out to us again for updated links.
>Q5: What should I do if the device cannot connect to Wi-Fi or set up a Bitcoin wallet/address?
A5: This is usually an operational setup issue. Please try the following steps:
(1) Wi-Fi Connection: Ensure you are connecting to a 2.4GHz Wi-Fi network (5GHz is not currently supported) and verify that the password is correct.
SSID: Enter your Wi-Fi name
Password: Enter your Wi-Fi password
(2) How to connect a wallet/payment address/Bitcoin address?
If you need to enter a wallet address, please fill it in the BTC address field on the configuration page.
If you have successfully connected, there is a BOT button on the back of the mainboard. Press and hold the BOT button for 7-9 seconds to reset the device. After resetting, you can enter your wallet address on the configuration page.
If the issue persists, please provide a specific error screenshot, and we will further investigate for you.

>Q7: After testing multiple mining pools, the progress is stuck at 70% or 80%. What should I do?
A7: Please try the following steps:
(1) Use a 5V 2A adapter to power the device and ensure the network is 2.4GHz.

stratum+tcp://pool.tazmining.ch:33333
>Q8: What should I do if the device frequently disconnects during operation and cannot maintain a stable connection?
