I can't find my bitcoin address and my bitcoin core is out of sync by 3 years


Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank.

(problem and solution summed up in last post of the thread)


My experience with Bitcoin is rather limited : I thought the idea was interesting, bought about 5 bitcoins one year ago and let them sit in my bitcoin core wallet (I had 4.9 bitcoins yesterday). Since my network is often slow, it is not very practical for me to run a bitcoin node and I often take time to catch up to the network when I start the application, so I decided to move my bitcoins from one wallet to another (Electrum) when installing a new version of my Linux distribution (mint 18).

I decided to send 0.1 bitcoin first to see if everything went smoothly (I'm really glad I did), now I see two problems (see screenshots below for more details) :
1) incredible fee amount : on Electrum I see 0.15 bitcoin fee for 0.1 bitcoin transfer in the transaction, so a total of 0.25 bitcoin. There should be a big red popup in bitcoin core "You're about to transfer the equivalent ~125USD but it is going...

That's a great question, which I remember asking myself that when I first started digging into Bitcoin.

Finding your bitcoin address (Desktop)

I assume you mean the number you see when you click on the "Wallet Address" link at the top of the browser view:

Which gives you something like this:

Sharing a Bitcoin Address

That Bitcoin Address can safely be shared with anyone, anytime without presenting any risk to the security of your funds.

You should be aware though, that once someone knows that an address belongs to you, they can view the full history of send and receive transactions to that address. You can see the same transaction history for this address at Coinbase, Blockr.io, Blockexplorer.com, or any of the many service that allow you to explore the Bitcoin blockchain. (What's the...

Giving out My Bitcoin Address | Localbitcoins


First time here and acquired my first trade. I went to a site that offers free prizes of bitcoins and they want my bitcoin address. Is this safe?


And where do I find my address?


I don't recommend using any gambling site, or facet. They're usually gimmicks and are quite unsafe.


Thanks. Where do I find it?


Are you using coinbase? If so go to Account Settings>Bitcoin Addresses> +Create New Address.


Give out as many public addresses as you want! Create new ones for each payee. Money can flow in, can't flow out with out the private keys.


you should use local wallet like multibit or web Blockchain wallet for faucet sites (btc for free) change address for each site (you can generate it in your wallet).

With the popularity of a bitcoin, more and more people are opening up bitcoin wallets, and naturally, people need to know where can I find my bitcoin address?

Essentially you will navigate to your blockchain wallet and click on the receive button. This will generate a bitcoin address for you. And you can generate a bitcoin address whenever you like. They all work and will always work!

You can also generate a bitcoin ‘QR’ code and store that on your computer, or put it on the website, or send it in an email. So I suggest doing both.

Why Bitcoin Core Won’t Sync

While bitcoin core is the original and most recognized bitcoin wallet, it is also extremely bulky and requires a ton of resources to run. With the bitcoin core wallet you have to download the entire bitcoin blockchain (over 8 years of bitcoin transactions) and keep it synced to be able to spend your bitcoin. The bitcoin blockchain is over 100 GB in size which is too large for most users to store and can still take weeks for some people to download before they can use the wallet. Many people accidentally send bitcoin to their core wallet without realizing how long it will take to sync, then decide they would like to use another wallet. This guide will help you recover your bitcoins from bitcoin core, then transfer them to a lightweight wallet that is easier to use.

Can't figure out the difference between Bitcoin Wallet and Bitcoin Address? And what's the Bitcoin Client, please? Our article would clarify all these for you and you'll become a Digital Currency expert in no time!

What is Bitcoin Wallet?

What is Bitcoin Address?

If you want to buy bitcoins, you should create your new bitcoin address, then use it on 247exchange while making a "buy" order in the "Bitcoin Address" field. After you pay the order, we will use this address to send you bitcoins, so they will appear at your Bitcoin Client.

What is Bitcoin Client?

The original Bitcoin client is called Bitcoin Qt (Bitcoin Core). It has all necessary functions, but such client is not simple to use, because you will have to install "heavy" application to your computer which takes about 25 GB of your computer's memory. This application is logging all bitcoin transactions from the begining, that's why it needs a lot of disk space. Another...

The days where we could mine Bitcoins on our laptop are long over. The requriements for Bitcoin are so high that you would barely be able to mine enough to cover for your electricity costs before either your GPU or hard drive becomes corrupted. Ask yourself a valid question – Can I make any type of mining profitable from your computer without an ASIC? Not likely, according to public opinion.
Bitcoin blocks are now so complicated that a 100Gh/s ASIC will produce about 0.0426 BTC per day, so taking that into account a laptop would hardly be able to keep up.

You Will Damage Your Laptop

As mentioned, it is extremely dangerous to use Bitcoin miners on your laptop due to the hardware damage that occurs. Many have destroyed their laptop cooling fan, hard drives, laptop screens and even monitors. In one particular case, a Bitcoin miner found that the external Bitcoin device he plugged in to mine had caused his computer to warm up and then freeze solid due to the...

A cool function of Bitcoin not mentioned in introductions is its message signing and verification feature. I'll use the Satoshi client on a Mac as the example but the same functions are available in the wallet at blockchain.info and in any decent Bitcoin client.

Suppose you have a dispute with a vendor you paid in bitcoin. They say you didn't pay them the correct amount or they didn't get paid at all. So you show them the record of the transaction.

Great, says the vendor, but how do I know that's your coin?

In the Satoshi client, go to the "Receive Coins" tab. At the bottom, you'll see an option that says, "Sign Message" (you can also go to File > Sign Message). Enter the Bitcoin address that you own that initiated the transaction (that's the address to the left of the green arrow in the transaction record mentioned earlier) into the address form. Write your message and then hit the "Sign Message" button.

The signature generated is unique to the address...

Bitcoins are a decentralized form of crypto currency. Meaning, they are not regulated by a financial institution or the government. As such, unlike a traditional bank account, you do not need a long list a paperwork such as an ID in order for you to establish what’s known as a bitcoin wallet. The bitcoin wallet is what you will use to access your bitcoins and to send bitcoins to other individuals.

How To Setup An Account

You can acquire a bitcoin wallet from a bitcoin broker such as Coinbase. When you open up a wallet through a certified broker, you are given a bitcoin address which is a series of numbers and letters, similarly to an account number for a bank account and a private key which is a series of numbers and letters as well, which serve as your password.

Download a Bitcoin Wallet

A wallet is a program that sits on your computer and gives you a wallet address, this is a unique string of numbers and letters that you will use to receive bitcoins. Download the client for your computer from https://bitcoin.org/en/download

After installation, you will have to save a file called wallet.dat, keep this file safe, as this contains your unique wallet address within it, including all bitcoins that you will gain. If you lose this file, you cannot recover any bitcoins it contained.

Create a Pool Account Once you have a wallet address, create a pool account. A pool is a huge collection of other people working towards gaining bitcoins. Due to the complexity of mining a bitcoin, it has become unrealistic to solo mine–the act of processing millions of numbers to solve the block...
