How do these machines generate money?

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.

Can anyone start mining crypto-currencies?

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

What are the disadvantages of mining?

Most machines consume a lot of electrical energy, produce a significant amount of heat and generate a lot of noise.

You must choose your machines according to your ability to tolerate these three factors.

Safe place for your gain?

When you mine your gain will be stored in a wallet. 

We recommend that you use a hardware wallet, to be the full owner of your coins. 
Do not keep all your earnings in an online wallet (exchange, pool…).

The best known and most trusted hardware wallets are:
Trezor and Ledger.

Why is RAM essential for Ethereum mining?

In order to mine Ethereum and Ethereum Classic, your device must load a DAG (Directed Acyclic Graph) file into memory (RAM). This file grows over time, and when this file is larger than your available memory, you can no longer mine.

For example, here is a projection of the size of the DAG file for Ethereum:

– Over 4Gb on December 2020
– Over 6Gb on March 2024
– Over 8Gb on May 2027

How to understand profitability?

The real-time earnings show you the benefits you can expect from a device if you already owned and operated the miner.

Can I change some local parameters in calculation?

Yes, in the ‘Local preferences’ section of the footer, you can:

  • Change default currency (USD, EUR, GBP, more to come…)
  • Electricity cost (price of KWh)

 

Why do profits change when I refresh the page?

Profits are calculated in real-time according to device specifications and external variables:

  • Network difficulty
  • Block reward
  • Coin value
  • Exchange rate
