// 1. Calculate daily coins mined by this GPU
// Formula: (Your Hash Rate / Network Difficulty) * (2^32) * (Seconds in a Day / Block Time) * (Block Reward)
// For many PoW algorithms, 2^32 is a constant related to difficulty calculation.
// Block time varies greatly by coin, so we'll derive it from difficulty and total network hash rate if possible, or make an assumption.
// A common simplification for estimation: Total Network Hashrate = Difficulty * 2^32 / Block Time
// Let's assume a block time or derive it if we can estimate total network hash rate.
// A more direct way to estimate is: (Your Hashrate / Network Hashrate) * Total Coins per Day
// Network Hashrate = Difficulty * 2^32 / Block Time (seconds)
// Let's use a simplified common approach that relates your hash rate directly to difficulty and reward.
// Estimated Network Hash Rate (MH/s) = (Network Difficulty * 2^32) / (Seconds in Day) – this is incorrect without block time
// A more robust approach without knowing block time:
// Consider the probability of finding a block.
// Your probability per second = Your Hash Rate (H/s) / Total Network Hash Rate (H/s)
// Total Network Hash Rate (H/s) = Network Difficulty * 2^32 / Block Time (seconds)
// Let's use a common formula that directly uses difficulty:
// Coins per day = (Your Hash Rate in H/s * Block Reward * Seconds per Day) / (Network Difficulty * 2^32)
// Convert GPU Hash Rate from MH/s to H/s

## Understanding GPU Hash Rate and Mining Profitability
Cryptocurrency mining, particularly for Proof-of-Work (PoW) coins, relies on computational power to validate transactions and secure the network. The **hash rate** is the fundamental metric that quantifies this computational power. It measures how many guesses (hashes) a mining hardware, such as a Graphics Processing Unit (GPU), can perform per second to find a valid block solution.
**What is Hash Rate?**
Hash rate is typically expressed in hashes per second (H/s), but due to the immense numbers involved, it's commonly reported in larger units:
* **Kilohashes per second (kH/s):** 1,000 H/s
* **Megahashes per second (MH/s):** 1,000,000 H/s
* **Gigahashes per second (GH/s):** 1,000,000,000 H/s
* **Terahashes per second (TH/s):** 1,000,000,000,000 H/s
The higher the hash rate, the more potential your mining hardware has to solve blocks and earn rewards.
**Factors Affecting Mining Profitability:**
Several variables determine whether mining a particular cryptocurrency is profitable:
1. **GPU Hash Rate (MH/s):** Your hardware's raw hashing power. Higher is better.
2. **Mining Pool Fee (%):** Most individual miners join mining pools. These pools combine the hash power of many miners to increase the chances of finding blocks. In return, they take a small percentage fee from the rewards.
3. **Electricity Cost ($/kWh):** Mining is energy-intensive. The cost of electricity is a major operational expense. This is usually measured in kilowatt-hours (kWh).
4. **GPU Power Consumption (Watts):** How much electricity your GPU uses while mining. This directly impacts your electricity bill.
5. **Coin Block Reward (Coins):** The number of new coins awarded to the miner (or pool) that successfully finds a block. This reward often halves over time through "halving events."
6. **Network Difficulty:** A measure of how hard it is to find a new block on the network. As more miners join and the total network hash rate increases, the difficulty adjusts upwards to maintain a consistent block discovery time. Conversely, if miners leave, difficulty decreases.
7. **Coin Price (USD):** The current market value of the cryptocurrency you are mining. A higher coin price significantly increases potential revenue.
**How the Calculator Works:**
The calculator uses these inputs to estimate your daily mining profitability.
* It first converts your **GPU Hash Rate** to hashes per second and accounts for the **Pool Fee** to determine your effective hashing power contributed to the pool.
* It then estimates the **Coins Mined per Day** based on your effective hash rate, the **Coin Block Reward**, **Network Difficulty**, and constants related to the mining algorithm (like the `2^32` factor).
* The **Estimated Daily Revenue** is calculated by multiplying the coins mined by the current **Coin Price**.
* The **Estimated Daily Electricity Cost** is determined by converting your GPU's **Power Consumption** to kilowatts, multiplying by the electricity cost per kWh, and then by 24 hours.
* Finally, the **Estimated Daily Profit** is the difference between your daily revenue and your daily electricity cost.
**Example Calculation:**
Let's say you have a GPU with:
* GPU Hash Rate: 50 MH/s
* Mining Pool Fee: 1%
* Electricity Cost: $0.15 / kWh
* GPU Power Consumption: 200 Watts
* Coin Block Reward: 12.5 Coins (like Bitcoin's initial reward)
* Network Difficulty: 50,000,000,000,000 (50 Trillion)
* Coin Price: $3,000 USD
The calculator would process these values to give you an estimated daily profit, taking into account both the potential earnings from mining and the cost of electricity. Remember, this is an estimation, and actual results can vary due to network fluctuations, changes in coin price, and varying block times.
