No. Bitcoin balances can't be negative. It's a GUI bug on blockchain.info, one of many bugs, just like it's possible to show transactions there that will never confirm. I don't trust their block explorer for anything unconfirmed.

A more fundamental problem is that full nodes don't earn anything. Miners take $40 million per day at current prices, full nodes get nothing. Just 1% of $40 million per day would be enough to fund tens of thousands of nodes, and 1 GB extra per week shouldn't be a problem at all.

Either way, Bitcoin needs to scale to keep up with demand.

A working Lightning Network would be great, but it doesn't work yet. Blocks should have been increased years ago, long before miners were earning $10 million per day on fees alone, and long before it was heavily debated and dividing the community. It would have been a simple upgrade, just like Satoshi envisioned, and a great solution until the Lightning Network becomes available.

I'm using Bitcoin Core, but I wouldn't even know how to use SegWit addresses. It's nowhere to be found in any of the options, and the few times I looked for it, I couldn't find it either.

The New York Agreement wasn't really based on consensus, it was the miners fearing the User Activated Soft Fork. And - kinda as I expected - the miners backed out of the 2x part, because they profit largely from small blocks.

When I started with Bitcoin, 0.01 mBTC was enough for a transaction up to 1 kB. Fees are now about 500 times higher when measured in Bitcoin, and Bitcoin is worth 80 times more. That makes fees 40,000 times higher, in less than 3 years. It really pains me to see Bitcoin crippled like this. I can no longer make a few transactions to demonstrate to a friend how easy Bitcoin works, unless I want to spend $50 on fees. Many services are now asking a consolidation fee too, on top of my own fee. I don't care how it scales, but it really needs to scale. And not in a few years, it needs it yesterday.
Despite the high price, Bitcoin can't handle more users when it can't handle more transactions. Bitcoin Cash wouldn't exist if Bitcoin would have scaled properly.

No.

The fee is based on the transaction size (in bytes). Two inputs from two different addresses are the same size as two inputs from the same size.
Check my transaction: 3 inputs from the same (uncompressed) address produces a 583 bytes transaction.

I'll make you a deal I'll send you 50k bytes ($0.03), if you post your experience with a Blackbytes exchange here. I still need to review them on my own, but I appreciate your input too.

There are always worse scenarios, for instance if your computer is compromised, if you accidentally send the private key to someone else, or if you download a fake Electrum (this has happened before).

But if your computer is clean, and you're careful, you should be pretty safe.

My gut feeling tells me this isn't true, so I've sent zazarb a PM. Let's wait for him to confirm or deny this. Archived just in case.

I apologize for my paranoia. I've seen too many scammers and start assuming everybody is one now. Fady, I'm glad you're telling the truth.

That's no different than any other ICO or altcoin. What is different though, is that BetKing has an actual working product already.
The buyback also prevents BKB to bubble up in price like most altcoins do. You can't pump something that has a fixed price somewhere else.

It's kind of a hedge against a price drop. I trust BKB more than I trust Tether.

Use this one Don't post your private keys here!

Once you've imported all your funded private keys into Electrum, you can send the total balance to an address you own by yourself. Although I'm not sure how Electrum handles it if an address already have a transaction in mempool. Basically, you're double spending, which is something I've done from Bitcoin Core in the past.

Yes, that's called a double spend. But I'd get rid of coin.space before doing it.

If they still broadcast the transaction it can take a very long time to drop it.

I'll give you 50% of the value I can take out But seriously, you can't sell a wallet, because you can still have access to the old private keys, and the new owner can't know for sure you're not accessing it anymore.

Can you export the private keys (under the settings tab, according to Google)? In that case I'd say just import them into Electrum and try from there.

I don't think there's much you can do. You could try to accelerate it to get it confirmed, or just wait for it to drop from mempool.

That's normal. Most wallets use a different address for each transaction, for your privacy.

I can't tell you what Coin.Space is doing, but I can tell you this transaction did not get broadcasted. Both blockchain.info and blockexplorer.com have no record of it.
Blockchain.info does show an unconfirmed transaction from a week ago though.

It depends on how long they keep broadcasting the old transactions.

The receiving wallet doesn't matter, all addresses are treated equal by the Bitcoin network.

At least your one week old transaction really got broadcasted, so I assume your wallet is not just faking it.

I've seen threads like this more often recently, and most of the time the wallet.dat belongs to an altcoin.
Is there any chance you were into altcoins 4 years ago? My first guess was Litecoin, and 85f198bd1c8cd6f389b30ead2b6693390da4ae73f82d3a7aa3b3d85321d09880 shows up on that blockchain.

The transaction has 2 outputs: 0.01072006 and 10.05, both spend already.

There is no 0.005 in this transaction though. I can't imagine the same txid exists on another chain, so basically I don't know what happened.

The full story on the guy who forgot the PIN of his Trezor is on wired.com. Thanks to Saleem he got it back! He had 7.4BTC in there. I read the full story a while ago. I'd say start your search from there, contact Saleem, and ask (and pay!) for his help. Be very careful, as you'll only get one shot at flashing a hacked firmware. Good luck, and please update your results here!

Download the source code from bitcoinpaperwallet.com or bitaddress.org, put it on an USB-stick, and copy it to your offline LIVE Linux environment. Then unplug it before you use it.

Correct. You can of course just order it and go the easy way.

bitcoinpaperwallet.com uses the same system as bitaddress.org. I trust both sites, but it's important to read, understand and follow their safety precautions. I can also recommend to make a small test deposit and withdrawal before funding your paper wallets.

I haven't used their own CD, I used a standard Ubuntu or Knoppix disk (downloaded and burned onto a DVD).

Since you're posting this in "Technical Support": is there anything specific you need help with? If not, can you move (bottom-left corner of this page) this thread to Beginners & Help?

The same address received payments two times again this year (2017). Did you make those two payments, even though you lost access to the address 2 years ago?

Your password only works on your wallet, your seed phrase can be used to restore the wallet without password.

What happened exactly? Did you reinstall Electrum, restore your old seed, and still not see your balance?

I'm happy to help, but your story is a bit .. messy Please clarify my questions first.

Bitcoin is electronic cash. What you did, is like (anonymously) putting your money back in the bank's cash register, instead of depositing it into your account.

In this case, it looks like the exchange's address, which they use to consolidate other transactions to, then use it to pay withdrawals. Normally they use each address only once. (1Ltob7Pm2J6xyGteXpTjmSaBf1ph75LrEK was used twice because of your deposit back to that address.

I find this highly unlikely. I suggest to ask them to check again, they might have only checked customer's deposit addresses. If your initial withdrawal came from them, they must own that address.

Correction: it's 99%:
It seems like a small difference, but it takes 50% off of Tonych's share: he only keeps 1%.

You have a very good argument here. I too believe Byteball itself is already highly undervalued, and Blackbytes could be the holy grail of privacy. In a thread like Best Private Coin?, I'm the only one who mentions it, while Monero is mentioned many times (by people only posting for Activity).
In a way, Blackbytes are so private that most people don't even know about it. That makes the potential for growth enormous.

So you put all your eggs in one basket! It's a very risky strategy, but at least you follow what you believe in.

Using multisig makes it much harder to steal your Blackbytes, you could make it as big as you want and require a Linux PC, an Android phone and an iOS device to sign transactions, while you keep some other devices with the same wallet as backup (say 3 out of 6 multisig).
May I ask how far you've gone to secure your Blackbytes?

Please read up on Byteball and Blackbytes, it's intended to be used by as many people as possible, holding millions in it was never the intention. That being said, it's a steep learning process but the multisig makes it very secure. It's not even that hard, actually.
