Thanks for sharing this, it was actually quite interesting to watch.
They tell the entire story of Quadriga, the founders, and what happened. This is a reminder yet again of not your keys, not your coins.
I wasn't aware of the details of the story, and I quite enjoyed the watch. Recommended.

Since we're still in a fiat world in most countries, we need to pay for goods and services with fiat. If you're using a card for every day purchases, might as well get a card that gives you some sats along the way. I'm not talking about cards that allow you to spend Bitcoin, but cards that give you some sort of cash back incentive in Bitcoin after you purchase something in fiat with it. Also, there are some services that provide cashback in the form of Bitcoin, called satsback. Note that I'm not endorsing these products, I'm just sharing what I think is a reasonable deal. There's a lot of scams out there, and many platforms are basically useless because you can't really get the BTC out of it. These ones I think are at least useable, but let me know if you think otherwise about them and I'll remove them from the list. Also, note that you are probably giving up some privacy when using these tools (although this is true by using any fiat card). Here's what I've found so far: Feel free to add suggestions if you know of any other one. |

Would you say the average person's phone or laptop is safe enough for a Software wallet, even protected by password? Probably not. And yet, they use it for banking all the time. I still think unrooted phones are more secure than Windows computers. I trust my Android more than I'd trust Windows (which I don't use anyway), and I would never use any Windows computer to even check my email. I have some privacy issues with Android. Google can track you so much with Android. There's a log of even what apps you have opened and at what times. Plus all the location data, etc. It's incredible the amount of data that Google (or Apple) has these days on most of the people in the world. A device with some kind of open OS like Linux or OpenBSD, etc, is kinda the best bet these days. Although there's even risk at the CPU level. For the paranoid, RISC-V is getting a lot of traction these days (it's an open source set of instructions to build CPUs). |

You can add ledn to the list: | ledn | 6.25 | Daily | None | None | No | USDC | But it's worth repeating. Not your keys, not your coins. It's up to each person to see if it's worth for them to put their Bitcoin in these companies. |

BestChange just filled their last slot, so they should be moved to CFNP Thank you, everyone, for your applications. It was hard to make a choice.

Here it is: https://ignota.org/products/the-white-paper  I'm not sure if this is well known here in the forum, but in 2019 Ignota published a book that contains Satoshi's white paper, a guide and explanation of it, and also some content from the early days of the forum: Inside The White Paper:- James Bridle introduces the historical trajectory of cryptography and how it gave rise to the blockchain.
- The original Bitcoin: A Peer-to-Peer Electronic Cash System white paper by Satoshi Nakamoto.
- An extensive guide and discussion of the white paper by Jaya Klara Brekke that elucidates the fundamentals of the paper and examines how bitcoin has developed over the course of a decade.
- The appendix brings together a succinct collection of pivotal exchanges and dialogues in the early development of the blockchain technology from between 2008 and 2011.
The purpose of this little book is to explain how the blockchain works and why it still inspires. It consists of Nakamoto’s breakthrough 2008 paper Bitcoin: A Peer-to-Peer Electronic Cash System, a guide to it by blockchain aficionado Jaya Klara Brekke, along with appendices, an introduction by James Bridle and informative essays parallelling bitcoin with the cryptographic work at Bletchley Park that helped the allies defeat the Nazis. "I want to make your eyes shine in bright-eyed wonder as you reread the Bitcoin white paper, just as mine did," Brekke writes. That’s the peril and pleasure of the book: her guide mixes the off-putting ardour of a doorstep God botherer with excitement over the elegance and unrealised potential of Nakamoto’s idea.
Here's some of the quoted material from the forum, and the actual thread is here. Certainly, in December 2010 there was much enthusiasm from cypherpunks for WikiLeaks to link to bitcoin on their website for donations. In a fascinating thread on bitcointalk.org reproduced in this book, Mike Gogulski wrote: "Screw big business. Google, Microsoft and Wal-Mart can all eat flaming death as far as I’m concerned … where systems like bitcoin can be helpful is in making both government and big business irrelevant and obsolete." Seems interesting, and I think it's great to have the white paper accessible in multiple different ways. |

I see that my country still doesn't have any Bitcoin ATM since it's not showing any sign on the map you provided. I wonder when will I gonna be tried one of those ATMs and post my experience in this community. As one of the earliest bitcoin fans in our country, I should be one of the first to try the Bitcoin ATM whenever there will be available in our city. Anyway, is this map updated? I wonder if I can check it sometimes to see if there will be finally one to try on.
It's relatively updated, but there are some mistakes. The good thing is that this map uses the data from OpenStreetMap, which you (or anyone) can update. Here's how you can add places to the mapIf each bitcoiner here keeps their local OpenStreetMap section accurate, then everyone around the world will benefit. |

Yes. I knew coinmap. Does anyone know how reliable it is? As for sites that accept payment in Bitcoin not appearing and sites that have stopped accepting it continue to appear.
I know a site that accepts payment in Bitcoin near me and it does not appear. I guess I'll have to contact them and let them know.
Coinmap pulls most of the data from OpenStreetMap, which is like the wikipedia of maps. Anyone can edit OpenStreetMap, and set the Bitcoin Payment to yes or no. Here's more information about how to do that: https://help.openstreetmap.org/questions/29078/how-to-add-the-tag-paymentbitcoinyes-in-an-openstreetmap-editor-for-the-coinmap |

I see that the source code is not available for this miner. From the binaries published, I don't see any mac build. Will there be a build for mac?, in particular for the Mac Mini M1. It natively runs arm64 and with Rosetta-2 it can emulate x86_64 architecture. I wonder if either the x86_64 or the aarch64 Linux builds can somehow be run in the mac directly. |

Mainstream media is actively pushing against Bitcoin, and a lot of people are just repeating what they hear there. The more you read about Bitcoin from first sources, like these ones, the more you realize Bitcoin is here to stay, and all the FUD and alts are irrelevant. |

I was looking at the Apollo Miner's software and it looks like it's closed source. Is it possible to run the Apollo Miners with an open source software like cgminer or bfgminer? jstefanop does have some cloned repos with changes from cgminer and bfgminer. I wonder if it's just one of those compiled, or if there's something different in the published binaries. Edit: Nevermind, found the answerSource for the UI is up on my github, backend firmware is all proprietary and built from the ground up for these ASICs (ie does not use open source cgminer/bfgminer). |

It's great to see so many places around the world that have either a Bitcoin ATM or are a merchant that deals with Bitcoin. Link to the live map: https://coinmap.org/view/#/world/12.06080906/-85.12207031/6 For comparison, here's a map with lightning nodes, available from https://explorer.acinq.co The company behind the Bitcoin map is called coinmap. They did make an announcement here some years ago: A lot of the data comes from OpenStreetMap, where you can just tag any business with this code: Key:payment Bitcoin tagging for businesses/nodes has been discussed on the tagging mailing list but maybe not yet voted on: payment:bitcoin=yes Bitcoin accepted as a payment method at the Point/Points of sale.
payment:bitcoin=no Bitcoin is not accepted.
payment:bitcoin=interval Bitcoin is accepted only at certain times; the notation for opening_hours=* can be used.
payment:website:bitcoin=yes Bitcoin accepted through a business's website yes. If it is not, then choose no.

I've only bought goods and services with Bitcoin, and each time I just bought the same amount or more with fiat to put it back into Bitcoin savings.
It would make no sense to me to buy fiat with Bitcoin.

While thinking about the relationship between Bitcoin and alts, I remembered that something similar happens in the animal kingdom. In the sea, there's a type of animal called Remora. They have evolved to attach themselves to larger animals.  Alts exist because of Bitcoin, and they ride along with it. Some people say that Bitcoin is less relevant now because alts are eating away its market-cap. But an interesting thing was recently discovered: Although it was initially believed that remoras fed off particulate matter from the host's meals, this has been shown to be false; in reality, their diets are composed primarily of host feces. |

~snip~ I've got to repeat myself, but let's not forget that there's a big difference in attack surface between an embedded device with secure element versus a full PC (Raspberry Pi counts as well) without secure chip and probably even without secure boot (old laptops, Raspberry), possibly even with outdated BIOSes that might be full of holes like a good Swiss cheese. I'll leave this article as a very current example of a severe BIOS bug: https://thehackernews.com/2022/03/new-dell-bios-bugs-affect-millions-of.htmlOf course, you can have also Linux kernel bugs, library bugs, and the list goes on - as well as cold boot attacks and everything I mentioned. On a hardware wallet, you have the SoC, the firmware, and that's basically it. There's much less code to audit and keep secure & updated than on a full PC. Like, if you're really worried, it's realistic to read the whole codebase of a hardware wallet, but it's impossible for one person to read through all the code that runs on an airgapped 'old laptop wallet' or a SeedSigner. This would include kernel and all libraries and packages. Yeah, that's fair and I agree with the issues that a PC or Raspberry Pi bring to the table. I'll start by saying that there's of course not a single best way of doing this, these are all security "guidelines" and no system is 100% secure. But you're missing one point, which is that you need physical access to the device. To have physical access to it you need to first notice it, and a hardware wallet is pretty obviously a device containing money, so the chances are that an attacker will grab it and try to hack it. A raspberry pi or an old computer laying around is way less tempting in the eyes of an attacker. |

So Bitcoin Core allows to do the same thing, most people have an old pc that they do not use, they can just install bitcoin core, generate a wallet, export descriptors to the online PC (the daily use PC), there you create a watch-only wallet, import descriptors and you will have a functional watch wallet (allowing to create new receiving addresses and create unsigned transactions) after a transaction is created you just copy the psbt file in a USB flash drive, bring to the offline PC, sign and bring back to the online PC to broadcast.
~snip~
Let me know your thoughts.
Basically a hardware wallet is a product, ready to use, with a company that can provide support for newbies. You don't need a hardware wallet, but it's easier to use for people in general. Bitcoin literally started with Bitcoin Core. Hardware wallets were created later on, for people that didn't want to deal with the setup. You can of course just have an offline pc (A raspberry pi Zero is ideal for this as it doesn't have any networking hardware) and run Electrum in it. PSBTs can even be transferred using a webcam through QR codes, it's pretty cool. But this is a DIY solution, which is not ideal for everyone. |
