In simple terms, blockchain is a public ledger including all (confirmed) bitcoin transactions that have been ever made.
Thousands of copies of blockchain are kept all around the world by thousands of people. This makes bitcoin decentralized and changing or removing the transactions impossible.
With this technology, transactions can be made without any need to a third party.

Binance isn't a wallet. It's an exchange.


I doubt bitcoin core is suitable for OP. For using bitcoin core, OP will have to download the full blockchain.
As already suggested, the best option for OP is electrum and I don't think he/she needs any alternative wallet.

As already suggested in the previous posts, for spending fund from your paper wallet, you can import your private key into electrum. But note that you would defeat the purpose of the paper wallet if you import your private key in a device that has been connected to the internet.
The purpose of a cold storage is that your private key doesn't connect to the internet at all. Otherwise, your wallet is no longer a cold storage.

By the way, why don't you create a HD wallet instead of creating a single private key and a single address?

Are you saying it's bad that there would be 128 possibilities for the last word? What's the problem with that?


I don't see any reason for not writing the 12th word. But if you have written down 11 words and don't have the 12th word for any reason, it can be easily brute-forced and there wouldn't be a big problem.

I think OP is referring to the QR code displayed when clicking on "Create new receiving address" in the GUI.
If you scan the QR code, you will get an address with uppercase letters and "bitcoin:" prefix.

bitcoin:BC1Q..........

Right. All your private keys can be derived from your seed phrase and that's all you need for recovering your wallet.


For spending bitcoin from your wallet, you should create an unsigned transaction on your watch-only wallet, sign it on the offline device and broadcast it using your online device.
In this way, you can make transaction without your seed phrase connecting to the internet.

All reports that are made for a post won't necessarily have the same status.
If a report is marked as bad, that doesn't mean all other reports are bad too. Moderators should handle other reports manually. It's possible that there's a good report among them.

Your report status will depend on moderator's action.
If the post is deleted, all the reports made for that post are marked as good. Otherwise, the moderators should handle all the reports one by one.

For more information, read the post made by halab before.

You can easily export all your receiving addresses from your wallet and check their balance on a block explorer.
To do so, open your wallet, click on "Window" button at top of the window and select "Receiving addresses".

You can also go to "console" and use the following command.


Note that if you have ever made any transaction from the wallet, it's possible that your fund is on your change addresses.

If a wallet or the tool you use for generating the seed phrase is open-source and the code has been reviewed, there's nothing to worry about.
If you still want to generate the seed phrase yourself for any reason, it would better to generate a random number and convert that to a seed phrase instead of directly going the word list.

Note that there are two coinbase wallets. One of them is custodial and the other one is non-custodial.
Of course, even the non-custodial coinbase wallet should be avoided. Because it's close source and we don't know how the keys are generated and whether they have the access to the keys or not.

To OP:
I recommend you to avoid any close-source wallet.
As already suggested above, for your bitcoin, you can use electrum. It's open-source and gives you full access to your fund.

No. In a DEX, you should be able to trade without relying on any third party and without KYC while in binance P2P exchange, binance acts a third party and you have to verify your identity.
Binance P2P may have some advantages like giving you more payment method options, but as said it's not decentralized.

A seed phrase can't include 25 words. The number of words should be 12, 15, 18, 21 or 24 and as already said in the previous posts, a 12 word seed phrase is secure enough.
By a 25 word seed phrase, you may mean a 24 word seed phrase which has been extended by an additional word or characters. If that's the case, note that the 25th word isn't a part of the seed phrase. That's called passphrase.

Mycelium allow you to create a wallet using a single private key.
To do so, you should tap on "Add account" button at top of the screen and then "Advanced & more" button under "Single address account".
With mycelium, you can even generate a individual  private key.

You probably mean seed phrase, not passphrase.
Seed phrase (also called recovery phrase or mnemonic seed) is different from passphrase. Seed phrase is a series of words, usually 12 or 24 words. Passphrase is the additional word(s) or characters which is added to the seed phrase for more security.  

As mentioned by OmegaStarScream above, the address in question belongs to binance.
Note that when you deposit fund into an exchange, they move the fund to their hot wallet. That's normal and that's why the address is now empty.
Also, the address hasn't received all the 0.44 BTC you are talking about recently. It has received 0.41 BTC of that 0.44 BTC around 1 year and half ago.

I don't think "Project Development" board is suitable for altcoins/tokens announcements, even if the project is in development phase.  As you can see in the homepage of the forum, "Project Development" is under "Bitcoin" section and I think you should post bitcoin related topics there.
OP should make his/her topic in "Alternate cryptocurrencies" section.

From Guidelines for threads:

Note that with decreasing the difficulty adjustment period that much, we would decrease the accuracy of our estimation. To get a good average, we need enough samples.
Till now, difficulty adjustment algorithm has worked well and I don't think there is any need to change the difficulty adjustment period.

I don't have any information about metaverse, but whatever your project is, you are probably launching a token/coin.
If it's a coin, post your topic on "Announcements (Altcoins)" and if it's a token, post your topic on its child board, "Tokens (Altcoins)".

This is not true. Bitcoin difficulty determines how difficult it is to mine a block. But there is no way to know how many hashes a single miner should generate to solve a block.
It's possible that a miner with the hash power of only 1 MH/s can find a block.

It doesn't matter how many miners are trying to solve the blocks. There is no way to know that at all.
