Since you didn't specify which wallet you are using, we can't give you concrete information.
But "used" usually just means that you already received BTC to this address. This does not invalidate the address.
You can always receive BTC to the same address.
Whenever possible, use a new address for each transaction. But there is nothing wrong with using the same address multiple times (except for less privacy).

I'd recommend you to not use any web wallet. They are often buggy and increase your attack surface. The best would be to just switch to a desktop- or mobile wallet. They let you precisely choose your fee and are less vulnerable. (thread closed)
You can close it yourself. In the bottom left corner: lock topic |

I want to correct this, it is Bech32, also know that segwit wallet support both P2SH (compatible) and Bech32, but it does not support P2PKH (legacy) bitcoin address. But people like Bech32 bitcoin address because transaction fee is lower.
A "segwit wallet" doesn't "support" anything. There is no "segwit wallet". Segwit is an improvement. And the address format is called bech32. That's the "real segwit". Nested segwit is just P2WPKH nested into P2SH. That's not really segwit but good for compatibility with outdated software. I like bitcoin core too, it is a full client wallet, but not good for beginners as it needs more money space and subsequent backup of each addresses used to receive bitcoin [...]
You only need to backup your file once. Core uses HD wallets. [...] it is a secret and safe wallet but the device used for it must be free of malware.
This applies to every desktop-, mobile-, browser-based- and web wallet. As for me, I prefer electrum wallet just for the security sake.
Electrum is not more secure than core. That's a misconception you have. |

- I imported my seed from original Bitcoin wallet to Electrum to an offline
Has this seed / mnemonic code been generated offline? If not, there is no reason to use it on an offline computer now. It was initially generated offline using BitcoinCore, then the private key was imported to Electrum offline. What exactly did you import into electrum? A single private key for a single address? A master private key for all addresses? Or a mnemonic code (12/24 words) for all addresses? If the sensitive data has been created offline, you are definitely fine to regard that as a cold wallet. But what bothers me is that you might have not used the original core since it does not provide you a mnemonic code. Can you verify that you imported the master private key (starting with xprv.. yprv.. or zprv..) ? |

- I imported my seed from original Bitcoin wallet to Electrum to an offline
Which "original bitcoin wallet" are you talking about? Has this seed / mnemonic code been generated offline? If not, there is no reason to use it on an offline computer now. If you want a cold storage wallet, you need to generate the seed and mnemonic on an offline device. Importing it from an online wallet defeats the purpose of a cold wallet. |

Have heard so many confusing themselves about exchange and wallets, some choose to store their portfolio in exchange while exchange is not connected to private key.
Seems like you are one of those confused ones. Nothing is "connected" to a private key like you imagine. Spending BTC always involves a private key to sign the transaction. Custodial wallets / exchanges just don't give you access to the private keys (which is quite understandable regarding exchanges). You just have a balance on their website which entitles you to withdraw BTC. [..] So privacy is measured by percentage.
You can not measure privacy in percentage. Check my previous posts. |

Hier aber nochmal eine Warnung an den OP: Instant-exchanges sind dafür bekannt systematisch und gezielt zu scammen. Sie locken einen mit schnellen und günstigen Wechsel ohne KYC und sperren dein Guthaben dann. Daraufhin wird alles mögliche von dir erwartet (Perso, Herkunft der Gelder, etc..). Viele lügen dabei auch über den Standort des Unternehmens. Also bloß die Finger lassen von diesen Instant exchanges. Aber da du sowieso nur FIAT <-> BTC tauschst, sollte das eh nicht für dich in Frage kommen. Bleib einfach bei vertrauenswürdigen Handelsbörsen. |

Das beste wäre vermutlich du bleibst einfach bei Electrum.
Wie hast du die denn bisher gekauft?
Du kannst ja einfach so weiter kaufen. Der einzige Unterschied ist ja, dass du die Coins auf dein persönliches Wallet schickst.
Persönlich, kann ich dir Kraken empfehlen. Die haben einige Sicherheitsmechanismen implementiert, die bei anderen Börsen nicht zu finden sind.
Was die Sicherheit der Webanwendung angeht, sind die echt spitze.

Nowadays is much harder and it all looks in future it will be close to impossible. Nonsense. As someone who only ever buys and sells bitcoin without linking the trades to my real identity, and refuses to use centralized exchanges or complete KYC at all, it is much easier to trade privately than it was a few years ago. The interesting part is buying and selling with a linked real identity on a centralized exchange, without any possibility to link those trades and coins. The cryptography we have available (e.g. blind- and ring signatures) is enough to keep us anonymous (i.e. using coinjoin) without any link between 2 transactions. Privacy isn't only a matter of not giving out private and sensitive information, but breaking the link between transactions of which the counterparty has some information which could be assembled to create a detailed and sensitive profile. We made huge steps in terms of privacy through cryptography in the last few years. |

Using only wallets that connect you to blockchain is safest
Using wallets that require email or private key is not best at all, I remember when Satoshi created bitcoin core wallet, it has private keys, and if difficult to use for a start there are still many wallets that follow the rules of privacy like hardware wallets, if expensive there are still wallets that cost nothing than downing their software on phones and computers that follow the rules of privacy unlike third party wallet which has no privacy. I can not use third party wallets, not possible.
1) Every wallet has private keys. Otherwise you wouldn't be able to sign transactions 2) Using a desktop wallet does not guarantee you privacy (e.g. electrum: the server you are connected to knows all of your addresses, your balance and your IP address. This makes it extremely easy to track you). 3) Hardware wallets are just the hardware. You still need software as an interface. If you are using wallets like trezors web interface, ledger live or electrum, your privacy is not existent. Revealing your privacy makes your fund not to be private, also never use kyc payment methods
If I have conbase, and I use credit card or other payment method that have enough identity of me, my privacy is completely lost in connection to the bitcoin I bought with the card and also in connection to the wallet I used. Very possible this can be used to track any wallet or exchange I send the coins to. That is why I like p2p exchange.
Not necessarily. You could easily mix the coins by either using a mixer or coinjoin. This will break any link between your original coins (tied to your identity) and the coins you later have in your wallet (which you will spend). The use of bitcoin ATM, best way to 100% privacy
I suggested another idea below how privacy can be 100% but I will like people to talk about this, I think with bictoin ATM for depositing bitcoin into blockchain through keys in wallets, I think this is a good idea to 100% privacy as p2p exchange may not be sufficient. P2P may not lead to 100% privacy.
You never get 100% privacy. Privacy can't be measured in percentage. You always have to include the anonymity set when talking about privacy. With an ATM where cameras are directed at you and required KYC for amounts larger than X (like a few hundred $?) and where people can observe you while using them, i wouldn't call that privacy. |

By coincidence I stumbled upon satoshi's reasoning why you can't remove a private key from Bitcoin Core: If you were able to delete a bitcoin address and someone sent to it, the money would be lost. They're only about 500 bytes. This quote is from when core didn't use HD wallets. Today, deleting a private key and the associated address shouldn't be a problem. It would be kind of blacklisted in the wallet.dat file (i.e. not showing / scanning this address). The seed however would still reproduce the private key of this address. Technically this could be feasible, but probably unnecessary and problematic. |

Waiting to hear back from cashapp. Binance said they couldn't help
Of course they can't. They sent the transaction to the address you gave them. The only way you get your USDT back is that cashapp is voluntarily retrieving them for you. Please note that you have no right to get your USDT back. If they are willing to help you, that's goodwill. Otherwise you are out of luck. |

You obviously don't know what a hash is. And obviously you are not talking about your wallet. Please read this article first. Afterwards you should know what a hash is. Then you might understand that you were actually talking about the representation (which doesn't play any role at all). P.s. if you bought wallet.dat files, you got scammed. |

You could start using bitcoin the way it is intended to be used.
A new address per transaction.
Do not reuse addresses. Give each person you are dealing with a new address.
This way you'll always know which address belongs to which person/transaction.
If that is not an option for you, jackg already suggested an electrum plugin for uploading them to an external server.

If you would be able to sign a message with an watch-only wallet, this would also mean you could sign transactions. In this case it wouldn't be a watch-only wallet anymore. The master key can generate all the bitcoin addresses of the wallet, and I think also their public keys, as an address is just a portion of the public key.
The address is created out of the public key. The public key is derived from the master public key which is then hashed to retrieve the address. But a signed message needs both the address and private key to work, doesn't it?
You only need the private key to sign a message. But with the private key you also can automatically derive the address. The public key then is needed to verify the message. Master private key -> master public key Master private key -> child private key -> public key -> address Master public key -> child public key -> address A watch-only wallet is created using the master public key. |

Could you please post your logs? Upload them to https://pastebin.com/ or a similar service and post the link here. Since you didn't provide any useful information (OS, armory version, ..), i am going to assume that you are a windows user. In this case the logs can be found in C:\Users\Owner\AppData\Roaming\Armory. |

You might want to consider switching to a proper wallet.
A browser-based wallet doesn't give you any advantages over a desktop wallet, but introduces new vulnerabilities and might give you a false sense of security.
If you are only accessing your coins from a single device, chose a desktop wallet.
If you need to access it from different devices, chose a suitable wallet for each device/platform sharing the same seed.
With a desktop-/mobile wallet, you are not just increasing the security, but also get access to more features compared to web- or browser-based wallets.

[...] würdet ihr mir für die zukunft ein anderes wallet empfehlen?
Kommt, wie immer, darauf an wie bzw. wozu du dein Wallet verwendest. Generell ist jedes Open Source Wallet schon mal besser als ein Web Wallet. Electrum ist für Einsteiger auch recht gut geeignet. Wenn du dann natürlich besondere Ansprüche hast (wie z.B. Privatsphäre), dann gibt es dafür natürlich deutlich bessere Wallets. Aber Electrum ist schon mal ein guter Anfang. |

I smell BS
1) Running 32 cores hard I can't hash and write 2,600,000 lines to an SSD with the machine doing nothing else for 5 minutes
2) New user we never heard from before having an issue like this.
3) Copy / pasting that much data in Windows will slow it to a crawl unless you have gigs and gigs of free RAM.
Let's do some math. OP posted 21 lines which need 1912 Byte of storage. That's roughly 91 Byte per line. 91 Byte * 2.600.000 Lines = 236600000 Byte = 225 MBThat's definitely not too much to copy/paste and doesn't need gigs of free RAM. Copy/pasting that definitely will take some time (maybe ~5 minutes?). So technically.. OP could tell the truth. However i agree with you, that this seems to be quite unlikely. Especially since OP only registered here to create this thread. |
