Since Cove Wallet doesn't use Tor (at the time of writing), this is a good option for using our sats anytime while maintaining privacy.

Pre requirements
-Cove Wallet (https://covebitcoinwallet.com)
-tailscale
-static address for the node

Procedure.
	1	install the Cove Wallet app on your smart device.
	2	install Tailscale on your node, it will ask you to create an account using email. Install the application on your smart device and use the same email that you used on your node.

	3	on your smart device open the Tailscale application and log in, you will see two devices connected with their own IP (your node and your cell phone, in my case), press the name of your node and your addresses will appear, IPV4, magicdns, IPV6, in addition to the expiration of your access key. https://image.nostr.build/2067862c814619327ff5f3a43682d8a642cf5123a89b7763b8e96f7fb83fc2d6.jpg

Test
We are going to copy and paste the IPV4 address into your browser, the log in of your node should appear, in my case it is umbrel.
With this we know that there is a connection with our node.

Connect tailscale to Cove Wallet
- On our device, open the Cove Wallet app and select the three lines in the top left corner. Then, select Settings > Node > Electrum Custom. Paste the IPv4 address and add 50001 to the end, this is the port used by Electrum on our node.
You can also use magicdns and add port 50001 to the end.
For example: http://200.200.100.81:50001

If everything is ok you should read a connection notification.

Important considerations
-Wallets are updated and only work with IPv4 when tailscale is enabled.
-Tailscale keys expire, pay attention to updates and repeat the process.

Any idea if Bluewallet will have integration with NWC?
Since AlbyHub requires the Pro version to create subaccounts, the following tutorial makes sense: https://stacker.news/items/666183
The only thing missing would be the custom lightning address.
It would be great if Bluewallet could create NWC accounts and use the staker news custom lightning address as a bridge. 

Bluewallet + NWC?

Thoughts of the Day! ordinals

It isn't, but if they are going to put images and information on the blockchain, immutable and permanent, it is better for everyone to see patents than memes.

**Context**
Ordinals on the Bitcoin network are a way to inscribe unique data (such as images, text, or even videos) directly into satoshis (the smallest unit of Bitcoin, 1 BTC = 100,000,000 satoshis). This is achieved by taking advantage of Bitcoin updates, such as SegWit (Segregated Witness) and Taproot, which allow more data to be stored in transactions.

Unlike NFTs on Ethereum (which usually point to an external link), Ordinals store the image directly in Bitcoin, making them immutable and permanent.

**Instead of storing their memes on the Bitcoin network, why don't people store patents that are being censored for national security reasons (the Invention Secrecy Act) and that can help humanity improve in various areas?**

May Bitcoin help humanity, apart from the obsolete monetary system.

Free the world.

LNDHub + MyNode questions

things someone new should know about bitcoin?

It seems that AI is understanding this better than many people.

I asked deepseek the following: things someone new should know about bitcoin, how to use it and make it part of their life?

What is Bitcoin?
Definition: Bitcoin is a decentralized cryptocurrency, meaning it is not controlled by any government, bank, or central entity. It is a form of digital money that operates on a peer-to-peer (P2P) network.

Underlying technology: It runs on blockchain, a secure, public ledger that records all transactions.

2. Key features
Decentralization: There are no middlemen like banks.

Limited supply: There will only ever be 21 million bitcoins, making it scarce and potentially deflationary.

Security: Transactions are encrypted and verified by the network.

Transparency: All transactions are public on the blockchain, but identities are pseudonymous.

3. How to get started with Bitcoin
Get a wallet:

Types of wallets:

Hot wallets: Connected to the internet (mobile, web, or desktop). Examples: Exodus, Trust Wallet.

Cold wallets: No internet connection (hardware or paper). Examples: Ledger <dont use ledger>, Trezor, Coldcard.

Important: Keep your recovery phrase (12 or 24 words) in a safe place. It is the only way to recover your funds if you lose access to your wallet.

Buy Bitcoin:

Exchanges: Platforms like Binance, Coinbase or Kraken allow you to buy Bitcoin with fiat money (dollars, euros, etc.). <search for apps made on your local area or country>

P2P: Platforms like LocalBitcoins or Paxful allow you to buy directly from other people.

Bitcoin ATMs: In some countries there are ATMs where you can buy Bitcoin with cash.

Learn how to send and receive Bitcoin:

Each wallet has a unique address (a string of numbers and letters). To receive Bitcoin, share your address. To send, enter the recipient's address and the amount.

4. How to integrate Bitcoin into your life
Savings: Many see Bitcoin as a long-term store of value, similar to digital gold.

Payments: Some stores and services accept Bitcoin as a payment method. You can use it to buy products, services, or even donate.

Investment: Bitcoin is volatile, so some see it as an investment opportunity. However, do your research and only invest what you are willing to lose.

Remittances: It is a fast and cheap way to send money to other countries.

5. Risks and Precautions
Volatility: The price of Bitcoin can rise or fall dramatically in a short period of time.

Security: Protect yourself from hackers and scams. Never share your private keys or recovery phrase.

Regulation: Bitcoin laws vary by country. Find out about regulations in your area.

Scams: Be wary of offers that are too good to be true, such as Ponzi schemes or fake exchanges.

6. Continuing Education
Resources:

Books: "The Bitcoin Standard" by Saifedean Ammous.

Websites: CoinDesk, Bitcoin.org.

Podcasts: "What Bitcoin Did", "The Pomp Podcast".

Communities: Reddit (r/Bitcoin), Twitter, Telegram.

7. Long-term mindset
Bitcoin is an evolving technology. Adopting it requires patience and continuous learning.

Don't get carried away by FOMO (fear of missing out) or panic during price drops.

Walkthrough NFC Sticker and Buzzpay PoS



In the context of Bitcoin, "watch-only" wallets (view-only wallets) are wallets configured to view balances and transactions without having access to private keys. These wallets are useful for monitoring activity at an address without risking compromising funds, as they do not allow signing transactions.
After protecting the private key (12 or 24 words) in metal sheets or washers and we want to add funds without entering the private key all the time, using an NFC sticker with the zpub can be very convenient, this is a tutorial on how to achieve that . 

**Prerequisites:**
Have a Bitcoin wallet and know how to get the zpub.
Download the bluewallet app on your device, it is the app that we will use to open and obtain the information read from the NFC sticker.

Compound Annual Growth Rate (CAGR) Bitcoin

https://image.nostr.build/00d7e3efc5d46ec5c69aa81300833a3f66fd6cd4001b5ad5f8017e348f502de9.jpg

Not necessarily, it works without direction from Alby, but you would be creating invoices all the time.
The idea of ​​adding alby address is to receive sats without generating invoices all the time.


The **Compound Annual Growth Rate** (CAGR) is a measure that describes the growth of an investment over a period of time, assuming that profits are reinvested at the end of each period. It is expressed as a percentage and provides a constant growth rate that, if applied each year, would result in the final value of the investment.

The formula to calculate the CAGR is:

https://image.nostr.build/8d8f99ec4ff7fa997df678e636ddf77036bfb3baba8424eb84351641af02a8d5.png

Where:
- **Final value**: the value of the investment at the end of the period.
- **Initial value**: the value of the investment at the beginning of the period.
- **n**: the number of years in which the investment has been made.

The CAGR is useful because it allows you to compare the growth of different investments or assets over time, eliminating the volatility that can occur in shorter periods.

https://image.nostr.build/b1fa50f1c84dc43ecf386097de34276766e9a176364f0dd2c56cf6984d7a7962.png

If we see the image, we could buy Bitcoin every September and we would have returns greater than standard and poors (market), returns greater than inflation (USD terms). 

You could have interesting returns if we use dollar cost average.
