I don't argue with you, hardware lever airgap is much safer without a doubt but my point was that software level airgap isn't very dangerous for average computer user who lives in average neighborhood. There are people who don't know how to disassemble Laptop.What if I am that person and live in a village in a big house, in masonry walls and I have password set on my Wi-Fi? So if I don't type Wi-Fi's password in computer, computer won't be able to log in. To be honest, I don't argue with you because your advice is the most correct one, I am just stating, I don't feel like software airgap is dangerous in some cases. Overall, I suggest everyone to follow your advice for better security.
I wouldn't call it dangerous, per se, but just less secure than a hardware airgap. As I've said above, a software airgap is still much more preferable to a standard hot wallet.
What is considered a software airgap? I don't understand how software could help being airgaped? Like a software that blocks WiFi or one that blocks Bluetooth? |

Hi.
Perhaps I don't understand the question so I need to verify. What do you want to store on the external drives? In most cases, you can just run the wallet on the laptop and in case of an emergency you can use the seed backups. That's for the hot wallet.
In case of cold storage you can generate it on the air gapped laptop using electric and store the backups on physical media, produce the xpub so you can generate a view only wallet and then you can delete it from the air gapped laptop
Do you mean you want to run your own node (Bitcoin core most likely) so the Blockchain needs to be downloaded to the HDD?

Το θέμα με το να τρέχεις το Bitcoin είναι να το τρέχεις σε έναν υπολογιστή που μπορεί να το σηκώσει και με κάποια άνεση.
Σε τελείως θεωρητικά πλαίσια ένα Raspberry pi μπορεί να το τρέξει, στην πράξη δεν έχει νόημα γιατί τα specs είναι τόσο χαμηλά που δεν θα μπορεί αν το τρέξει σωστά. Και επίσης με την έλλειψη τσιπ τα raspberry pi είναι δυσεύρετα και πολύ ακριβά ειδικά στην Ελλάδα. Άσε που τα εξαρτήματα στην τοπική αγορά είναι ανύπαρκτα.
Καλησπέρα αλάνι. Έχω RPi 4b με 8 GB ram και τρέχω πάνω του bitcoin core + electrs + sparrow terminal και θα βάλω και monero node σε νέο tutorial. Γενικά νομίζω παίζει άψογα το RPi για αυτή του δουλειά. Παλιά έτρεχα Umbrel πάνω σε ένα ολόιδιο RPi και έπαιζε φανταστικά! Συνολικά δεν είχα δώσει πάνω από 150 ευρώ για Pi 4, case, φορτιστή και 1 TB HDD. Από skroutz μπορείς να το βρεις με 70. Δεν τρέχει γρήγορα, αλλά για σπιτική χρήση είναι ό,τι πρέπει. (Σηκώνει και c-lightning) Επαυξάνω! |

Hardware wallets are no longer safe since Ledger claim that they can extract your seed if they want with just an update and even if you didnt update your wallet they
may do it without your permission in the moment you connect to internet
Hi. Hardware wallets are perfectly fine if used properly. Ledger wallets are not. But thankfully, they are not the only ones available out there. |

I checked it out. It is absolutely essential to have the respective SeedSigner to Monero, but as far as I can see, it's under development. I wouldn't use it to store important amounts there. Instead, I would rather dedicate a spared laptop (which costs less than a RPi zero), airgap it, and install the officially supported Monero GUI wallet from getmonero.org.
Man, I totally agree with you and everyone who says that, but unfortunately I don't have an old laptop or pc or any device like that. But as far as the MoneroSigner is concerned, until it is properly released and tested I wouldn't use it either. |

Ok, Electrum, Sparrow and Bitcoin Core are top notch. I really don't see any other option anywhere near them. I have opened this topic in the past, in case it helps, to compare Electrum with Sparrow. |

I have been using this address for some years now, so i got some money from Si^D^^ recently but what about those satoshis which i got when i was not in that campaign ? I transferred some satoshi to some other wallets before the campaign too. So all those wallets become suspected  Yes, if you have received coins to the same address, then it is obvious that you are the owner of the address. If you gave me the address A to send you money there and you also gave it to another user, then all that money is now blended together and if someone tracked my transactions, they would also see the other user's payments on that address. Having seen that, I strongly recommend using the swap method that I explained above. |

The only thing I wish for, having had some difficult times lately, is to be healthy and full of energy.
May you all be blessed with health and positivity.
Merry Christmas!

I thought the same in 2017  I hardly knew about Bitcoin in 2017  60 sats/vB is definetely a lot in absolute terms, but for the current period it isn't that big. I mean, I had a payment I needed to make, so I combined 3 UTXOs setting the fee rate at 60 because I didn't know if I would have this chance again in the near future. |

That sounds expensive if you don't need to consolidated funds any time soon.
My current personal strategy is not to jump off the deep end at price higher than 10 sats/vB, sure , everyone makes it on their own regarding the current situation with mempool.
But how do you both know that the fees will drop? I believe high fees are here to stay! Unfortunately. Yeah, it is expensive anyway... But I really don't think fees will drop. |

Alternatively, if you don't know what you're doing, buy yourself a signing device like SeedSigner. It requires minimum technical knowledge to setup, and is completely airgapped.
SeedSigner is in fact one of the best projects out there. And unfortunately not a lot of people talk about it. People prefer to use Ledgers... I mean, what the ... Anyway, o_e_l_e_o recently told me about this: https://monerosigner.com/ which is the essentially a SeedSigner fork for monero. I just mention it because, you never know who could be interested. |

Fees now have dropped to 80~ sats/Vbyte, if nothing much changes, in a few more hours you may get away with 40 sats transactions, there is a large wall at around and above 40 sat (almost a whole day's worth of transactions) so I think 40~ sats would be a good level to consolidate if you are rushing and don't want to wait, I think we would eventually in a few days get to 10-20 sats, but probably never again see 1-2 sats unless something major happens.
Thanks mikey. Personally I took the chance to consolidate some inputs and also make some pending payments at 63.5 sats/vB. |

What OS did you run? Mine is downloading the monero blockchain now and the temp is currently 43.8 celcius. I don't remember exactly with Bitcoin but I can tell you for sure that it never went over 58-60 celcius.
But RAM is very important for this. So 8GB work much better than 4GB.
Raspbian. Mine was above 70 for most of the time, but again your cooling method makes a huge difference. Having the entire casing as a heatsink is undoubtedly better with what I've had on hand. RPi4s were notorious for overheating actually, might've been the issue with the earlier versions. RAM is important, but RPis are pretty expensive so I had to skimp on it back then. RAM shouldn't affect temperature anyways. To be honest I have created a node as a series of tutorials for Bitcointalk here. This node runs Raspbian Lite and to be honest the temperature went close to 65-67 degrees during the IBD. The other node that I have runs Start9 and the IBD went very smoothly and much faster than the other one's. I used to have Umbrel too and I don't remember any issues too. I just switched to Start9 because I loved its simplicity and the fact that it is much easier to customize. |

I think I ran it with my RPi 4, 4GB. How were your temps looking during the synchronization? Mine was fairly hot throughout, granted that it was just a heatsink and not a fancy heat dispersing case.
Not to mention, it took weeks.

I second what is said above: Don't use Raspberry Pi. My Pi 4 was overheating constantly when running a node and I had to get active cooling on it.
Out of curiousity, what where you running on the Raspberry and how much RAM did it have? I run 2 Raspberry Pi 4b 8GB RAM and I never had overheating issues. I use this case on both of them and the temperature never exceeds 58-60 celcius. It has passive cooling and there is no noise at all. |

Why is this particular transaction considered spam? I see a multi-sig paying another multi-sig and a miner. Sure, the dust output is weird, but how's that harmful?
Harmful? I don't think Bitcoin is harmed technically from these transactions. Bitcoin works as expected, increasing the fees. It was intentionally built to do this. The problem is that blocks like this: https://mempool.space/block/00000000000000000002f83ab72267be24e81ec374b726f94d2ae784fcd9c442 are full of transactions where the output is a 546 sats UTXO. Essentially the recepient won't be able to do anything with a 546 sats UTXO. At the same time, 546 sats is the minimum UTXO size allowed in Bitcoin, so it looks like people fill blocks with dust outputs. P.S I didn't check the past of these transactions to see where the money come from, but it is suspicious, in my opinion. Question for everyone more technically savvy than me: Could those be direct payments to the miners for some reason? Because if you think about it, you will see that these transactions pay for example 50,000 sats on fees (to the miners) and 546 sats to an address. |

May God bless his soul.
May God bless his family.
May God bless both icopress and GazetaBitcoin for this contest.
I don't know if God exists, but right now, I hope he does and I hope he hears our prayers.
I would like to abstain from the contest, but please leave this message here, so my prayer can be seen.

Do we have any statistics about Ordinal profitability? I mean, the medium priority fee right now is 154 sat/vb, and an Ordinal transaction is way above the median size. If it takes 10 bucks to have a median sized transaction confirmed, then how much does one pay to create an Ordinal? A thousand? And another thousand to sell it? How's this profitable?
The only thing we know for sure is that someone attacks Bitcoin with transactions like this: https://mempool.space/tx/51818e244c6dd93ece167ab78fe934068e229cdccd54d294e88226d2bb9f800dThere is a huge amount of dust transactions. So, this is strong evidence that some people spam the network and one of the possibilities is that they use money earned from selling ordinals. Of course I don't have the time to try to prove it, but don't you thinks that's a possibility? To be honest, I am not against Ordinals, I just want normal transaction fees for users like me to be able to use Bitcoin for regular payments.
I seriously doubt this can happen... If I had a guess, I would say that high fees are here to stay... |

Thanks, she loves it! She's been ill at home for the past few days.
I hope the little foxpup will make her feel better.  You 've been both very unlucky with illnesses lately... |

I am honoured to create something beautiful for your lovely daughter. I present to you Miss MehMeh, a small, pinky puppy who loves Bitcoin. (If you don't like it, I will re-create it)  Yay! I am so glad I've been there! Needless to mention, Crete is full of many other wonderful places (which I visited too or, at least, partially), such as Spinalonga, Knossos Palace, Mount Ida (the place where Zeus grew up), all the historic relics of Minoan civilization... And these are just a few of Crete's beauties!
Greece is beautiful! I hope BlackHatCoiner agrees! Let us know in case you need anything specific. I 've never been to Spinaloga though! Good catch! OMG you did an amazing job here hihi! Thank you so much!  I have a few suggestions for making a few changes but I'll tell you in PM, to not derail this topic even more than having already SEVENTY-SEVEN pages of derailment =))) Absolutely! |
