About Miner

A mining device uses powerful processors to solve the complex puzzles used to secure and validate transactions on a blockchain. By providing some of the global hash power needed, you receive rewards and get paid in crypto-currency. Then you can choose to keep coins or exchange it for other coins or currency.

Yes, mining has become easier to set up and understand. But you should consider mining as a high-risk investment, return on investment is not guaranteed, and returns are highly variable due to the volatility of the cryptocurrency market.

Most machines consume a lot of electricity, generate a lot of heat and make a lot of noise.

You must choose your mining machine based on your tolerance for these three factors.

When you mine, your earnings are stored in the wallet. Please DO NOT share with your wallet account to any other, otherwise, you may loss your crypto. There is no way to get them back after they were sent to others.

We recommend that you use a hardware wallet and become the full owner of your coins. The best known and most trusted hardware wallets are: Trezor and Ledger. We don’t sell this hardware wallet and are not responsible for any issue related to the any wallet.
