I did an installation of Bitcoin Core 23.0 and I manged to download all the blockchain. Every time I access to the GUI it works perfectly but when I try to access "sudo systemctl start bitcoind", I got this error:
[~snip~]
Dez 07 18:59:33 btcnode bitcoind[121021]: Error: Specified data directory "/home/goldasbtc/.bitcoind" does not exist.
I'm not much of a linux guy, but this error line looks to me as being the meaningful one. Does bitcoin use this same data directory when ran normally (ie. does the folder really exist?) What can be the reasons sudo cannot access that folder? Maybe you can chown/chmod there or set up a different data folder that can be accessed by both? Again, I'm not that much into linux and I may be wrong. |

Nu īnţeleg cum zici. Eu īnţeleg că participanţii vor primi codul īnainte ca acel cod cāştigător să fie ales şi trimite adresa
Eu īnțelesesem īn primă fază că doar cāștigătorii vor trimite informații. Acum, după īncă 2 citiri īncep să-ți dau dreptate. participanţii vor primi codul īnainte ca acel cod cāştigător să fie ales şi trimite adresa odată cu participarea alături de codul său. Īnainte ca premiul să fie atribuit unui cod, organizatorul va avea o listă care va arăta aşa
483920182 - Nume1, Prenume1, Strada X1, nr. Y1, etc.
283021737 - Nume2, Prenume2, Strada X2, nr. Y2, etc.
.....
143432989 - Numen, Prenumen, Strada Xn, nr. Yn, etc.
Păi asta mi se pare și mai nasol. Adică cineva poate să facă o tombolă cu niște abțibilduri și să facă rost de 100 de adrese fizice ale unor persoane interesate de bitcoin. Pare varianta benevolă a ce s-a īntāmplat după hack-ul de la Ledger. Păi tocmai de asta theymos sugera ca adresele să fie distribuite pe orice altă cale, doar nu prin Bitcoin Talk. theymos de fapt va avea acces doar la două informaţii. Numele membrilor participanţi şi codurile atribuite. Organizatorul va avea acces la două informaţii. Codurile atribuite şi adresele. De fapt nici măcar organizatorul nu ar trebui să aibă acces la mai mult decāt adresele cāștigătorilor. Cred că asta ar fi cea mai negativă parte. Īntr-o tombolă obişnuită, trimiţi adresa DOAR īn situaţia īn care eşti declarat cāştigător. Īn sistemul propus de theymos, toţi participanţii sunt nevoiţi să īşi listeze adresa īntr-o bază de date. Pericolul creşte substanţial dacă organizatorul are scopuri necurate. Exact. Suntem pe aceeași lungime de undă pānă aici. O concluzie ar fi că sistemul propus de theymos, īn forma asta cel puțin, pare mai nasol / periculos decāt ce avem acum. De aceea am venit cu sugestia de mai sus. Dacă toate adresele ar fi criptate de la bun īnceput sub un cod şi o parolă, atunci un pericol va fi diminuat iar celălalt va fi eliminat complet. Am o idee care s-ar putea să fie mai bună decāt criptarea. Eu cred că organizatorul poate să primească: 483920182 - Adresa1 de bitcoin 283021737 - Adresa2 de bitcoin ..... 143432989 - AdresaN de bitcoin Fiecare utilizator īși știe identificatorul. Adică tu știi că ești 483920182, eu știu că sunt 283021737 ș.a.m.d. (sper că nu greșesc). Utilizatorul īși dă o adresă de-a lui de bitcoin (preferabil goală și temporară), nu adresa poștală. Cāștigătorii vor trimite de pe un mail temporar īncă un mesaj către organizator, probabil conținānd un link de privnote. Iar īn notița respectivă va fi un mesaj semnat cu adresa de bitcoin "de mai sus", conținānd numele și adresa poștală, precum și numele concursului și "data de azi". E īntr-adevăr mult ping-pong de informații, dar s-ar putea să meargă... cel puțin dacă nu am īnțeles iar ceva greșit  |

Recently I got access to an encrypted wallet.dat which contains 4000 Bitcoins. The problem is, the wallet is encrypted
There are lots and lots of such "wallets" on the internet. The problem usually is not that the wallet is encrypted. The problem usually is that it's a crafted wallet that doesn't actually contain anything meaningful that could get you anywhere near to any private key. So if you bought this wallet, you most probably got scammed. Even more, it's rather uncommon to have email address only 9-10 characters long. My shortest ever email address was 14 characters long. This being said, I'll leave it to the others give you more technical details, since I don't have experience actually decoding / brute forcing wallets (I consider that a waste of time and resources). |

* BlueWallet supports hardware wallets and I think that this could need a special "chapter", especially as Electrum (which OP failed to mention!!!) on Android doesn't support HW
It supports hardware wallet like Coldcard, the Bluewallet make a PSBT and signed on the Coldcard with the use of memory card. Also support cold storage wallet as it can be used as a watch-only wallet to make PSBT which would be signed on the cold storage and transferred back to the Bluewallet to broadcast the transaction. I do not think it support using it with wallet like Trezor, Ledger Nano and some others. Woah, you're right, I've made a confusion. I wanted to test out my hardware wallet on Android "newer" bitcoin wallets and I thought that BlueWallet was the one this worked with, but no, it was Green Wallet (%!@$ color-names  ) I've also corrected the other post too. Thanks. |

they'd still have to add the coinbase transaction which is paying the miners themselves to the merkle tree (which ends up in the header of the candidate block) I didn't understand this... A block may or may not contain users' transactions. But even if miners choose to not add users' transactions they will normally still include the transaction that pays them ( = to the miners) the block reward (called the coinbase tx). And since 2 miners will most probably have different addresses to send to that money, the headers will be never identical. |

Imho autocorrect can do more bad than good. You can end up with a correct word, but not the correct one you wanted to use.
On the other hand, as Agbe also said, the modern browsers have, in a way or another, spellchecker integrated or available as plugin. And not only on smartphones. Red underlined words attract attention and help people improve on long term. This should be much more helpful than auto-suggestion or auto-correct.
A problem is the over-using of such tools too. I have a bad example, mine: I have spellchecker now set up for 3 languages and I can easily mistake and use sometimes a word from another language. But I think that this problem is a minor one compared with the huge amount of awfully written posts.

Eu cred ca asta poate functiona doar daca sunt mai multe premii identice. Asa organizatorul nu va sti care dintre cei 10 castigatori e cine. Altfel.. nu inteleg cum ar putea sa mearga asta. Plus ca poate deschide calea spre abuzuri: un castigator primeste codul, isi face 5 adrese de mail, cere premii pe adresa lui, a catelului, a purcelului, a bunicilor, socrilor samd, iar altii care afla tarziu ca a avut loc extragerea pot ramane cu buzele umflate. Cat timp exista un singur premiu sau un singur premiu 1, nu cred ca ideea asta poate sa mearga. Dar poate ca nu am inteles-o eu cum trebuie. Iar daca va exista o "cutie neagra" (criptata) unde eventual lumea sa se inscrie ca sa concureze... unii vor abuza si vor face inscrieri multiple. Daca se ramane cu utilizator de bitcointalk, undeva cineva (nu conteaza cine) va sti care este numele si adresa acelui utilizator. Daca theymos implementeaza o "cutie neagra" bazata pe numele/contul de utilizator va trebui sa avem incredere ca el si viitorii administratori de bitcointalk nu vor abuza de aceste cunostinte. Concluzia mea e ca oricum o invartim, sistemul nu este anonim. Si atunci de ce sa facem un sistem complicat cand ce avem este tot pe acolo? |

Miners are free to pick any number of transactions they want as long as the block size doesn't exceed 1 MB.
Edit: I forgot to mention that witness data are not counted in the 1 MB limit and any block can include up to 1 million virtual bytes or 4 million weight units of transactions.
It may worth adding that sometimes the mempool just doesn't have enough transactions to fill an entire block, hence no matter the block is not full and the miners would want to add more, they can't; the block will not wait for new transactions to come. Your transaction will have the chance to be mined in the next block. Depending on the fee rate you set for the transaction, it may take more time to be confirmed.
Again, I'll add that it depends on fee rate vs how full the mempool is. Plus, the fee cannot really be under the default minimum of 1 sat/vByte (but long ago in the past even 0 satoshi was sometimes OK as transaction fee). |

This key was received on purchase of bitcoins via PayPal about a decade back. Then, there was very little knowledge sources available online.
This sounds like a scam to me. Only you should know the private key, since that's the only "thing" that allows spending coins. If the seller also knew the private key then: * there's a high probability he gave you from start a bad/invalid key * if by chance the key was good, there's a good chance that meanwhile the seller has checked back and spend those coins/sent them to his own wallet. When you buy bitcoin you should get your own wallet (if you are not knowledgeable about this and it's a meaningful amount of bitcoin then you should use hardware wallet) and give the seller an address of yours where he will send the coins. The coins are really yours only if they (are confirmed and) show up in a wallet only you can spend from = only you have the private keys. Since the privkey has not been activated for many years, is there any possibility of keys invalidity?
Sorry, that's not how bitcoin works. |

I am glad that somebody has started a BlueWallet tutorial here. And I'm also glad that it's started as an open discussion, since (as Charles-Tim has pointed out very fast) some things are missing, incorrect or simply can be done better. I also recommend starting from the official website than the link for app (because one will be tempted to find the app on Play Store and end up with a clone sooner or later). Some additions/missing points: * if only the Android BlueWallet is discussed, it should be mentioned from start, in topic's title; BlueWallet exists also for desktop and iPhone. I would not be surprised there may be differences/missing features here and there. * BlueWallet supports hardware wallets and I think that this could need a special "chapter", especially as Electrum (which OP failed to mention!!!) on Android doesn't support HW * BlueWallet supports Lightning network (via a custodial wallet, however it's more than nothing) and that could use also a special chapter and workflow/tutorial Of course, all these can be added in time to OP (and I hope they will), although aylabadia05 should have been reserving 1-2 more post spaces for that. Edit: I've made a mistake/confusion, as Charles-Tim mentioned, BlueWallet also doesn't support well the hardware wallets, please read below. |

First check the validity of your priv. key on bitaddress.org . On the website go to wallet details tab and import the key in a plain text format. If it returns a valid bitcoin address, your key is correct otherwise some letters might be wrong. The error code you just mentioned usually occurs when one or more letters in the priv. key is invalid, might be a human error from your side.
OP, beware and make sure you don't enter the private key anywhere online. That's the recipe for disaster (ie getting your keys stolen). If you want to make this kind of tests, learn to get the source and open it in an offline (and safe) environment. My guess is also that you've probably mistyped something or confused some letters. |

1. Just make sure you don't report something you have already reported.
Is there a repercussion if that happened? If that happens the report will be marked as bad afaik. Not a repercussion that matters, stll some don't like bad reports in their stats. |

Your thoughts?
For me the old Nano S is still good enough and I agree that Ledger is again pursuing new directions - of course, they are supposed to bring more income - instead of fixing their actual (and old/known) problems that would keep their existing customers happy. Should I add that it costs the same as a decent 2022 Android phone? I mean, come on... |

What is the advantage in terms of convenience over paying by card? None. A lot to lose and nothing to gain.
Fees. I think that 10% of the fees VISA/Mastercard is charging (from one country's shops) can easily support a country's CBDC. But, really, politicians (and head of a Central Bank is imho more a politician than an economist) won't know nor tell the entire story. On privacy and so on, the thing is that it highly depends on how the CBDC is implemented. And there's a good chance even the bankers may not know all its "features". Just my 2 satoshi. |

Pai chiar e de ras-plans situatia. Te lamentezi ca nu mai scrie nimeni nimic pe aici si te trezesti cu unu` din asta, de-ti curge sange din ochi cand citesti ce scrie.
Complet de acord. Totuși... am cumva impresia că dacă īi luăm așa tare pe toți analfabeții, ... iar rămānem doar noi 3 să vorbim īntre noi. Probabil că nu e cazul chiar cu toți atotștiutorii habarnisto-analfabeți, dar na, poate că ar trebui să ne gāndim și la acest aspect. Sau sunt eu prea īngăduitor?! Daca o sa te plictisesti in continuare, o sa-ti povestesc si de bekli23, cel care a spart orice seed
Cred că era vorba de adrese, nu de seed. Și, probabil impulsionat de faptul că i-am dat dreptate (īntr-un fel), īncă lucrează la asta. |

Too little threshold.
200 per purchase / 1k per day / 100k per year is not too small threshold for normal people, let's be serious. You can buy and sell with bank transfer and buy with debit or credit card, they only accept cards issued in Europe.
Is it only me, or a company can find out KYC information from the credit card used for payments, or from the bank transfer? So imho it's not that much "non-KYC". On the other hand, the fees are not too big, I've seen actual KYC services with bigger fees. OP, did you experience hidden fees / big spread when you've used this service? All in all, at the first glance it's not too bad, but imho not that much non-KYC either. |
