+## ❓ Frequently Asked Questions (FAQ)
+
+### 1. Is it profitable to run an Ethereum validator in 2025?
+Yes. With ~5–6% base APR plus MEV and priority fees, a self-hosted Ethereum validator can yield 6–15% annually. Profitability depends on uptime, hardware, ETH price, and network conditions.
+
+### 2. How much ETH do I need to stake as a validator?
+You need **32 ETH per validator**. You can run multiple validators if you have multiples of 32 ETH.
+
+### 3. Can I run an Ethereum validator on Ubuntu 22.04?
+Yes. This guide is optimized for **Ubuntu 22.04 LTS**, but it also works with later releases (such as Ubuntu 24.04). Other Linux distributions may require adjustments.
+
+### 4. What hardware is required for an Ethereum validator node?
+Minimum recommended specs are:
+- 4–6 CPU cores  
+- 16–32 GB RAM  
+- 2–4 TB NVMe SSD  
+- Stable 100 Mbps – 1 Gbps internet connection  
+- 99.5%+ uptime  
+
+### 5. Can I use a VPS or cloud server to run a validator?
+Yes. Many people use providers like AWS, Hetzner, DigitalOcean, or Vultr. However, self-hosted bare-metal servers often offer better performance, reliability, and decentralization.
+
+### 6. What happens if my validator goes offline?
+Short-term downtime only reduces rewards. Extended downtime may lead to **penalties and slashing**. Maintaining 99.9% uptime is critical to maximize returns.
+
+### 7. What is MEV and how does it affect validator rewards?
+**MEV (Maximal Extractable Value)** are additional profits validators earn when proposing blocks. In 2025, MEV can add anywhere from $1,000 to $30,000+ per validator annually, depending on market activity.
+
+### 8. Can I withdraw my staked ETH at any time?
+Yes. With the Ethereum Shanghai upgrade, validator withdrawals are enabled. You can set a withdrawal address and regularly receive rewards, or exit the validator entirely when desired.
+
+### 9. Is it safer to stake with a third-party service or solo?
+Solo staking is safer long-term if you manage your keys securely. Third-party services charge 5–25% fees and carry counterparty risk. Solo staking gives you **full control** over your funds and rewards.
+
+### 10. What are the risks of running a validator?
+- **Slashing**: Misconfigured or malicious validators can be penalized.  
+- **Downtime**: Being offline reduces rewards.  
+- **Key management**: If you lose your keys, you lose access to funds.  
+- **Market volatility**: ETH price fluctuations affect real-world returns.  
+
+### 11. How long does it take to set up a validator with this guide?
+With the automated script, setup takes about **15 minutes**. The Ethereum sync process may take longer initially, depending on your hardware and internet speed.
+
+### 12. Can I run multiple validators on one server?
+Yes, as long as the hardware is powerful enough. Many operators run between 5–10 validators on a single high-performance server.
+
+### 13. Do I need to keep my computer online 24/7?
+Yes. Validators must remain online continuously. Consider redundant internet connections, backup power, or hosting in a datacenter for reliability.
+
+### 14. How do I monitor my validator’s performance?
+- System logs (`journalctl`)  
+- Prysm and Geth status commands  
+- External explorers like [Beaconcha.in](https://beaconcha.in/)  
+
+### 15. Where can I get support if I encounter issues?
+- [EthStaker Community](https://ethstaker.cc/)  
+- [r/ethstaker](https://reddit.com/r/ethstaker)  
+- [Ethereum Staking Discord](https://discord.gg/ethereum-staking)  
+- Official docs: [Ethereum.org Staking Guide](https://ethereum.org/en/staking/)
