Antpool sucks. Instead of reporting the bug, they're making lots of blocks with zero transactions in Litecoin. I can't want for POS in both Ethereum and Bitcoin.

The problem with the thundelightning network is that it eventually eliminates the incentive for mining blocks if you move the majority of transactions out of the blockchain, when block rewards are close to zero there won't be any fees to collect if everyone is going off chain, then what's the point of the blockchain. Also, who will regulate the cost of using that network, node operators will compete on a market basis which will bring huge centralization once the likes of corporate giants realize they can have valuable information in their hands by routing these payments. Centralization will mean censorship.
It is not Bitcoin, it's a trap.

How long does it take for my balance to unlock?

Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.

How can I prove that I sent a payment?

The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).

How do I buy Monero (XMR) with Bitcoin (BTC)?

There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.

How do I buy Monero (XMR) with fiat?

How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?

There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration.
That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.

How do I mine Monero? And other mining questions.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.

2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:
  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.
You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.
If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.
Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.
Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

To restore your wallet with the 25 word mnemonic seed, please see this guide.
To restore your wallet with your keys, please see this guide.

3. Wallet: Ledger

How do I generate a Ledger Monero Wallet with the GUI or CLI?

This question is beautifully answered on StackExchange. Check this page for the GUI instructions, and this page for the CLI instructions.

4. Nodes

How can my local node become a public remote node?

If you want to support other Monero users by making your node public, you can follow the instructions on MoneroWorld, under the section "How To Include Your Node On Moneroworld".

How can I connect my node via Tor?

This question is beautifully answered on StackExchange.
