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

Umbrel + Albyhub + Alby Go Accounts

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.

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.

Getting Started with Alby Hub

DarthCoin

uncle jim 
https://stacker.news/items/701502/r/articfoxb

In this tutorial we explain how to connect Alby go to your node through Albyhub, with this we can have our sats custodian and use our getalby address to receive sats without generating an invoice.

Prerequisites
Have a node, in my case it is an umbrel node.
Have open channels,liquidity

**Steps.**
1. In our node we go to applications and add alby hub from community apps. (See image)
https://github.com/getAlby/umbrel-community-app-store.git
https://image.nostr.build/a96aba0f9cf3f8536af4f062318ad634635592f3b606d2ae6fb24b71a51997a3.png
2. We install the alby hub application.

3. We enter alby hub In the connections section > add connection > isolated (we will use isolated to create new accounts with their own balance) > we enter the name of the account in my case it will be my alby account, articfox@getalby.com (it is just In order to distinguish them, I will do this procedure for the accounts of family and friends)> an unrevealed QR code will appear, for now we move on to step 4.

https://image.nostr.build/0605000ef9a10be8081fe442badfd19f76ad3667e8efc8b479f08f5b46599511.png

4. We download the alby go cell phone app (https://apps.apple.com/us/app/alby-go/id6471335774) 

5. In Alby go > connect wallet > name the wallet (i name it articfox@getalby.com)> read the QR code from step 3

*In order to use our getalby address you must connect nostr wallet to our account using web page*

6. In AlbyGo we go to settings (In the upper right corner)> and copy export wallet, it will help us connect with our getlaby address.

7. In our browser we enter https://getalby.com/ > setting > wallet configuration >link to your own wallet >nostr wallet connect your and we copy the information from step 6.
https://image.nostr.build/579fe1fa9c1a4eabd09fd7aba496f9d3e529c99ecbe075f8ab5071b53ee026b0.png

8. Remember to add your alby address in setting in the alby go application.

https://image.nostr.build/bd6b325fdd5074eb16cfc9b9da7d5ce9cea2b061104566eefdbe926339e355d0.jpg

With this we have our node as custodian of the sats, we create an account with a 0 balance to start receiving sats (and be able to make more accounts for friends and family), we connect our getalby address with our wallet to be able to receive sats without generating invoices.

*Recommendations* 
* The person who controls the node must have liquidity at all times.
* The node must be connected 24 hours a day.
* If the node disappears, the sats of the linked accounts also disappear.
* In Alby go save the export Wallet secret.

A company accepts payments in bitcoin but does not send you the product, under any excuse they could simply tell you that they will not send you anything and keep the sats, the problem that is seen is humanity scamming people, is there any way to solve this? 
If bitcoin becomes too desirable more people will be scamming their customers unless it becomes legal tender and has legal implications and the idea is to separate the banks and the state from the currency. 

How to solve the problem of scams in companies that accept Bitcoin ?

After reading Bitcoin Standard by Saifedean Ammous, the following book is a book that has not had enough exposure and debunks many questions such as:
Bitcoin is a bubble? Is it a ponzi scheme?

I leave you the link to this book about bitcoin that I thought was great. (see below)

**Best Privacy Practices for Withdrawals from an Exchange**

OK, story time:
osmowallet.com is an exchange app that allows you to buy, sell, receive and send Bitcoin and lightning with very low purchase and sale fees (like many other apps) they started in Guatemala and moved to El Salvador, their partners are IBEX, Strike so you can receive your remittance with them and they have currently expanded to Costa Rica, Mexico and the United States...
According to Osmo, to "strengthen compliance and protect users" they made an alliance with https://www.blockpliance.com
I leave the tweet (X) https://x.com/osmowallet/status/1819089931823706449
Until now we can only assume that all partners use blockpliance if they want to operate in El Salvador such as strike and ibex.
It doesn't hurt to know how to send satoshis safely to our wallet.

I bought a bitaxe to learn about mining, at first I connected it with public-Pool, obviously I don't expect to earn Bitcoin by mining with a bitaxe.

I found out that Braiins Pool now has Lightning payments so I decided to create a Braiins account and connect my bitaxe.

Guess who is earning 30 sats a day 🙃😎

I created this tutorial for my children, they like bluewallet, it is simple for them, I know that there are Zeus and other apps with better functions that use Tor.

Since Bluewallet stopped using Tor, this is a good option to use our sats at any time.

**Pre requirements**
-bluewallet 
-tailscale
-static address for the node 

**Procedure.**
1) install the Bluewallet app on your node and 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.

**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 bluewallet**
-on our device we open the Bluewallet application and select the 3 dots “…” in the upper right corner (settings) > Network> Lightning settings > paste the IPV4 address and add at the end: 3008 is the port that Bluewallet uses on our node.
You can also use magicdns and add the port :30008 at the end.
e.g.    
http://200.200.100.81:3008

**Create accounts**
We can now create accounts connected to our node using tailscale.
In bluewallet >press the “+” sign> lightning>create
A QR image will appear with an address at the bottom, we will use it later to create the same account but with a local network.
E.g. 
lndhub://user:password@http://host:port
lndhub://numbers and letters:number and letters@http://IPV4:3008

**Create the same account but on a local network**
Once the account with tailscale connection is created, we can recreate the same account.
In our new Lightning account we press “…”> export/backup> copy the account 
We import the existing account but we will change the host to the local umbrel host, for that we go to the “+” sign in bluewallet > lightning > import Wallet > we paste the backup of the tailscale account and modify the end with our local umbrel ip .
E.g.
lndhub://user:password@http://host:port
lndhub://numbers and letters:number and letters@http://umbrel.local:3008
lndhub://numbers and letters:number and letters@http://10.90.87.191:3008

You already have the same account on the local network and with tailscale.

**Important considerations**
-Accounts with IPv4 only work and are updated when tailscale is activated.
-tailscale keys expire, so it is good to create the same account on the local network and then modify it with the new IPv4 that is generated after the previous one expires.
-The account may cease to exist and with it your sats if the node ceases to exist, an account for personal use is recommended. https://image.nostr.build/5ef960e8b503f1470d7488dd404ef8f650c6a35f75d4076d3979d478b5664fc3.jpg https://image.nostr.build/4952aac246d9ae0db7ca9103084b892ea3b9fbbbcf79463531f8c0311b23c72b.jpg https://image.nostr.build/2067862c814619327ff5f3a43682d8a642cf5123a89b7763b8e96f7fb83fc2d6.jpg https://image.nostr.build/15ac1a4ba69a337a8f1f1fa585b92c4a84fa823dc252d6657294c58dc4f22e8a.jpg https://image.nostr.build/a2f2231a49cb34532686cc4f024f0d0555e6482aa36db6bba27d06d5bd030cc9.jpg

How to create a Ln account connected to your node using Bluewallet and Tailscale


Bluewallet no longer has the Tor function, therefore it can no longer connect to our node through this means.
Our existing accounts will not be able to sync and we will not be able to use our sats.

Zeus has the Tor function and we can import the existing account by connecting it to our node and you can continue using it.

Procedure
In the Zeus app in settings press the "+" sign select LNDhub, select Tor and select existing account, (we are going to import the existing Bluewallet wallet) with this we will import all the existing funds that we had.

-In bluewallet copy the account address

In the account press "..."> export/backup
The address will look like this.
E.g.
lndhub://123abc:456defg@http://toraddress.onion
lndhub://user:password@http://toraddress.onion


see image, (1) in username put the numbers and letters before ":"
(2) The password is the numbers and letters after ":" and before @
(3) host is the tor address after @ https://image.nostr.build/63e74315fd15ce0e777b38eefaadbc8a353ec62b0712a709950fcd15c90f45a3.jpg
