# Ethereum Earnings
All Ethereum rewards produced by the power of mining will be distributed in 3 different pools according to what your preference is:
* Flex Pool: Perfect for those go are not sure about Ethereum mining business and prefer to earn a little less in exchange for having their tokens available all the time
* 30 Days Locked Pool: Perfect for those who are in the mining business for the medium-long term so they have no problem leaving their tokens in staking for longer periods.
* TMT - BUSD LP Pool: Designed to reward those who want to add liquidity to the project and make it even more stable
## Historical graph of Ethereum profitability
Apart from the price of ETH, there are other variables that may affect the profitability of mining, such as Gas (fees paid to miners) or the amount of transactions in the blockchain. Regardless, ETH mining is relatively stable when compared to other forms of investment, but to more accurately show these variations here is a graph that shows the Ethereum mining profitability per day since January 2020. As we can see, the rewards for Ethereum mining have been increasing making the business more profitable since then.
## Equation for the APR
$$
APR = Rewards (USD)/Staked (USD)
$$
Assuming the rewards are always the same, if the amount staked in a pool is reduced then the APR will be higher, and if the amount staked in the pool is higher, then the APR will be reduced.\
If rewards don't change:\
Higher stakes --> Lower APR\
Lower stakes --> Higher APR\
\
Also, as the amount ($) staked depends on the price of the staked underlying asset ($TMT), if the price drops then the APR will be higer, and if the price goes up then the APR will decrease.\
If rewards doesn't change:\
Higher price --> Lower APR\
Lower price --> Higer APR

## Variables in Profitability
The variables that exist when calculating the profitability of mining are:
* [**Hashrate of the market:**](https://app.gitbook.com/@theminingtoken/s/tmt-mining/~/drafts/-MfFOT4XvhhE2BvTnR3n/tecnical/what-is-ethereum-mining/hash-rate) Affects the amount of Ethereum mined
* [**Ethereum Price:**](https://app.gitbook.com/@theminingtoken/s/tmt-mining/~/drafts/-MfFOT4XvhhE2BvTnR3n/tecnical/what-is-ethereum-mining/ethereum-price) Affects if you want to calculate your rentability in USD
* **Price at which you buy $TMT:** This will determine the amount of time you need to recover the investment. Early investing will, of course, relate to a faster
At every time 1 $TMT = 1 MH ([Mega Hash](https://app.gitbook.com/@theminingtoken/s/tmt-mining/~/drafts/-MfFOT4XvhhE2BvTnR3n/tecnical/what-is-ethereum-mining/mega-hash))

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://theminingtoken.gitbook.io/tmt-mining/ethereum-earnings.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
