nun habe ich meine alte wallet.dat ins Verzeichnis kopiert
Nun steht im Bitcoin Core jetzt seit heute morgen "durchsuche erneut...."
Leute ich bin dann raus
Nun ja.. was erwartest du denn? Core legt eine Datenbank mit allen UTXO an. Also quasi mit allen Coins die du empfangen hast. Wenn du dann plötzlich das Wallet austauschst, muss Core ja die Blockchain erneut durchsuchen. Durchsuchen heißt hier nicht alles erneut herunterladen und verifizieren. Ich bin heilfroh, daß ich in diesen Mist, bei dem niemand weiß, wer das kontrolliert und wer dahinter steckt, kein Geld investiert habe
Eig. weiß jeder, der sich auch nur ein paar Minuten damit beschäftigt hat, dass niemand das kontrolliert. Außerdem kann ich dir das nicht glauben, dass du nicht gern bei 1€ eingestiegen und bei 15.000€ ausgestiegen wärst  wenn ich mir quer durch das Forum die Berichte so durchlese, dann ist diese Entscheidung mehr als klug
Huh? Welche "Berichte" meinst du denn? Die von den Leuten, die nicht mal wissen wie sie ihren Toaster zu bedienen haben und desswegen Coins verloren haben? Oder die, von der Aluhut-fraktion? Letztendlich werden die Regierungen den Kram sowieso einstampfen
Auch wenn das deine Art ist, den Frust rauszulassen.. Wir wissen ja wohl beide, dass das nicht passieren wird  |

I am quite sure I have the right address applied because I only have one address and I have been using this wallet / address for years
Do you see this address somewhere in the Transactions tab, i.e. a transaction to this address which is marked as incoming transaction ? |

It makes perfect sense since it adds a level of security, if your seed is compromised your funds are gone unless you use a passphrase, the passphrase for the backup is not your seed it is to decrypt the backup which has your seed, if the attacker gets access to your backup passphrase but not to the backup itself you are still safe. Of course you would never have the backup and the passphrase for the backup in the same location.
You understood correctly, but in this case the passphrase to restore the backup it is 12 words, the backup I believe it also includes the pin, duress pin, and brick pin.
Of course this makes sense. But using 12 words as a passphrase to encrypt the mnemonic code can be quite irritating. Especially for new user. The passphrase can be chosen freely. Everyone can be free to chose 12 words or 11 or no words at all to encrypt it. But generating a 12 word "mnemonic" to decrypt the actual mnemonic code is a not that smart approach IMO. Rather let the user set any passphrase. |

Nothing can be compressed without losing quality but this compression allows you to reduce size while making it almost impossible for eye to detect the difference between two.
Compression without losing quality is possible. There are two types of compression: lossless and lossy compression. The lossless compression is quite limited and lossy compression can still be done without humans noticing any significant difference (i.e. because the human eye is more sensitive to brightness than to colors -> reduction of color data easily possible). P.S. There are two benefits of this compression. Less data when using mobile network and less load time of images, as a result faster and better performance on every device. Personally, I prefer to see thread loaded in 3 seconds rather than in 7 seconds.
And this is perfectly possible with JPG. You just need to compress it further (i.e. by setting the quality factor lower). |

This is based on your own investigation and let's say you already have screwed up by not getting relevant information on site or platform before you invest in. I bet this will serve as a lesson for you to study (research) before you give out your information online or probably using your money to gamble if it will be taken or not taken.
Next time, read the OP before replying with your generic and useless statements. Localbitcoins is a website to trade BTC P2P. This topic has nothing to do with investing into scam projects or gambling. The problem here was the (missing) security of the device (smart phone) and not the missing investigations before investing into scams. |

Don't look at the numbers/stats. The reduced quality isn't that important when showing a chart like in my example. Both pictures would be usable.
In your example, yes they would. But there is not a single reason to convert the image to webp. If you have a PNG or JPG image, just run the JPG compression (again) with a lower quality factor, and your image gets smaller in size I don't see any reason for using any other format than PNG for uncompressed and JPG for compressed images. |

A website "on blockchain" or about blockchain ?
If you want to create a fully decentralized web, you won't come far without much technical knowledge.
There are already a few projects out there which aim to do exactly that, creating a distributed, trustless web.
Maybe you could be a little bit more specific what exactly you are trying to accomplish?

First, props for using the proper format. Regarding your problem, is it possible that you don't have bitcoin core installed and synced? As previously mentioned, armory requires core. If you don't want to download and process the whole blockchain, you'd need to use a SPV wallet (e.g. wasabi) instead of armory. Regarding the requested logs from HCP, you can either export them by clicking File -> Export Log File or by opening it directly located in: C:\Users\USER\AppData\Roaming\Armory\

Put it in a card then.
"Dear x
Happy Birthday!
My gift to you is $100 worth of bitcoin.
Lets sit down together sometime over a beer and I'll help you set up your first wallet!"
This seems to be somewhat acceptable, i'd say. But i still don't think that it is a retarded idea to gift pre-generated paper wallets. Another thing is, that the majority doesn't know how to properly secure a wallet. So they definitely also won't be able to tell others how to. |

I often see suggestions like this when talking about gifting bitcoin, and I 100% disagree with them. You should not gift pre-generated wallets in any format, regardless of how secure/encrypted they are, because it teaches the person bad habits.
[...]
Don't trust, verify. Far better to sit down with them, talk them through setting up and backing up their own wallet, and then send some coins to one of their addresses.
Sitting down with them and talking about how to properly secure a wallet for a few hours doesn't seem to be a good gift tho. IMO this is a pretty bad present.. "Come here, sit down with me.. we gonna talk now, that's my gift for you..". A prefunded paper wallet is absolutely fine IMO. Just hand them the paper wallet. That is the gift. Afterwards you are still free to show them how to generate a wallet and how to transfer the funds (they even learn doing their first transaction this way). The problem is not really the pre-generated paper wallet, but how it is being utilized and explained. |

Anscheinend beträgt die Abhebegebühr 2.25 EUR bzw. 2.75 EUR. Und das mit den 1.20 EUR monatliche Gebühr, stimmt auch. Fremdwährungsgebühr beträgt 3%. Eine ausführliche Tabelle gibt es hier: Wirex - fees & limits |

I think 0.8.3 is so old that it does not have the functions described such as abandon transaction.
Actually i believe this functionality indeed got introduced later at some point. I also cant find the mempool.dat file to delete in the bitcoin programme folder (c:/program files/bitcoin). Am I missing something?
It is located in your data directory, usually: C:\Users\YourUserName\Appdata\Roaming\Bitcoin
Exporting the private keys should still work tho. |

Here is my problem. I do not want to have bitcoin-qt started every time I boot my computer and other computers on my local LAN. As It is using resources and also a lot of disk space on every computer.
You could just remove it from your autostart. Here is my thought but I do not know if it is possible.
Could I setup a bitcoind on my server using docker and access it from my bitcoin-qt?
It will have the latest blockchain downloaded in one computer centrally and it will not take my desktop disk space and recources and it will also run all day.
Also as there are more than one computer here I could setup different bitcoin-qt for each user and save their wallet info in their computer but the huge blockchain folder is going to be in the server.
AFAIK this is not possible the way you are imagining. But you could run your full node on the server and use SPV wallets on the clients to connect to it. Either electrum together with an electrum server on your server, or simply using Wasabi wallet on the client PC's and connecting them directly to your full node by editing the Config.json. The latter is probably the best option. Also an other idea I had was to use a web based bitcoin client installed on the server. With that I could login from my mobile phone remotely via vpn and access my wallet securely without having to use any other web wallets
Definitely possible, but security risks always exist when something is accessible from the internet. Only being accessible via a VPN does help, but shouldn't be considered absolutely secure. I would only use it for relatively small amounts. |

I know from experience that when dealing with older data, you can never assume anything, you have to do analysis without making any assumptions.
[...]
The right approach is to analyze everything, regardless of what the customer claims.
If you never assume anything and do stuff without making any assumptions, you will never succeed in anything. It is publicly known how wallets worked in the past and how they work now. And a CSV export of transaction data does not contain any sensitive information (i.e. private keys). So it is pointless. You are free to " not assume anything" and waste your time, but it won't help OP. |

Why not send her a Bitcoin Gift Card [...]
Bitcoin Gift cards? I never heard of something like that before and it doesn't sound like a good idea at all. The advantage of BTC is, that it is completely decentralized and trustless. And you propose to use a centralized entity which requires trust to gift some BTC? I think sending bitcoin gift card and give hardware wallet is better idea .
Anyway either you send a hardware wallet or paper wallet [...]
While a hardware wallet is a more secure option, i don't think this is always feasible. If you intend to gift like ~50$ worth of BTC, you'd first need to buy a HW wallet for ~90$. IMO a hardware wallet is only worth it when it costs less than half of your holdings. |

While not as super obvious as actually wrapping it in [ quote ] tags... at least they led with a direct link to the article that they've taken the text from. So, it's at least somewhat obvious where the text has come from.
IMO this is quite misleading. Quote tags would show how the whole post only consists of a single quote taken from a website. He didn't even write a single word on his own. I wonder whether his sig campaign pays for something like that.. |

Depending on what kind of image it is, I think most people wouldn't mind and wouldn't notice any significant differences. I just did a test and found a random Bitcoin chart in jpg format. I converted it to webp. Orignal JPG picture was 74 KB. The webp converted image is 36 KB. The converted image is over 50% smaller. The difference in quality is insignificant. The difference actually is huge. jpg: Image Size : 998x652
Megapixels : 0.651
webp: Image Size : 640x418
Megapixels : 0.268
You scaled the image down. You could also scale it down while keeping it JPG. And if you want to have a worse quality to save space, one could use the jpg compression again with a quality factor of 70-80ish. But scaling it down does not real count as compression. This can always be done and is independent from the file format. |

Why would anyone need a "bitcoinqrmaker" ? One could use any QR code creation tool. It doesn't have to be related to BTC at all.. Am i missing something? What would be the benefit? I've been using this service for a while now. Hands down the best API I have used.
Uhm.. ok. This basically is the best response: Unfortunately, your vouch doesn’t carry any weight or legitimacy as you are a Newbie, registered yesterday, that only has 2 posts. Security first.

Going a bit off topic, but why is that? I just downloaded the Blue Wallet app on my phone to receive some coins through the Lightning network...  Is it just because they don’t have enough reputation? Oh i didn't want to create the impression that the wallet is bad or insecure or something like that. Basically, what you said. I wouldn't call that wallet reputable because they actually don't have that much reputation yet. This definitely doesn't mean that it is not to be trusted! I was just expressing that it is not reputable in my opinion (yet). |

Tatsächlich? Ein super private web wallet von einem newbie vorgestellt was nicht open source ist und komplett server-seitig läuft hat sich als Scam herausgestellt? Da bin ich aber überrascht.. Hätte ich den Thread doch nur vor ein paar Monaten schon gesehen.. dann hätte ich wenigstens eine Warnung da lassen können. Aber schon krass wie so ein Thread hier einfach stehen kann und keiner warnt hier mal andere Newbies. Ich mein offensichtlicher kann ein Scam nun wirklich nicht mehr sein.. Das spricht definitiv gegen die DACH community. Immerhin ein Danke an dich bullrun2020bro, dass du hier ein Update bzgl. Scam Accusation hinterlässt. |
