email to BTC is very hard to do securely. where do you register addresses? what is a valid email provider? how do you secure email provider safety? etc. the problem ties in with various difficult to solve problems about networks of trust and keysharing. Paypal/Coinbase works because it is centralized. not what we really want.

BTC to email address does not involve an actual email

Ok maybe for notifications but the actual payment will be made via the bitcoin p2p network. The address could be a stealth address embedded as a txt record in domain's DNS zone. When you enter an email address in your bitcoin client it looks up the txt record to find the stealth address. It then generates a bitcoin address using the stealth address and sends the coins. Finally it will email the recipient the nonce or embed the nonce in the transaction.

Edit: Widespread adoption of DNSSEC would be a pre-requisite for the above.

If in future difficulties of every crypto currency start rising then it's means new and more heavy hardware will be needed??

That is more likely the case But with increasing Difficulty there will be a increase in price as well. And also it is gonna take months before it all happens. But it will only happen if the Scrypt ASICS come out. That I highly doubt even exist. Also we already have 70-80% miners that switched from BTC after ASICS came so until there are no ASICS for Scrypt we are good to go.

1st gen scrypt asics are already out. Reputable people have received units, put up reviews, group buys have concluded. It is legit unlike the early days of bitcoin asics. Check the mining hardware section and look for dualminer, asiabtc, lightning asic etc. Prices are too high though. You'll really feel the pinch when 2nd and 3rd gen chips get out.

Mind you GPU mining won't die. People like you will just switch to memorycoin and the like i.e. non-scrypt, non-sha256 alt coins.

I am using a mac so I opened the .csv with text edit and it says "address, private_key"

The .csv file is just a plain text file that you can open with any plain text editor or even a word processor if you have to.

The address, private key pairs are start on the second line. For example here's a test wallet:

Code:

address,private_key
1ETcLR3LULxJ9G9Pey5gLuC2Pbcrrrd1sV,5KGqiVAQStjj2zf6Q3a1SAYhP4UCw2Fh9PweN2bUTPDSatyme5S
1F4VxT6gPoKxp63e29fnBPEMeDa2ALegxi,5Jverug9poXUgi73A4n3ZRRLRCfqkNAYs5wZCLv5meNxh8qjr91
1LfjdJVsNUtFkbzjitSJuNkYNWZa7oZHeD,5JHcR5YmxBWggQazHHLHw5y43ogT3nNvsA2RufrKAtavRqswvhb

So you can get back your coins very easily.

- Run electrum

- Go to file menu > new/restore > navigate to a convenient location on your file system and enter a filename for your new wallet > click save

- Then proceed to create a new wallet as normal.

- Once you've created a new wallet import your private keys by Wallet menu> private keys >import. Click yes to make the warning go away and then enter each key on one line like so:

Code:

5KGqiVAQStjj2zf6Q3a1SAYhP4UCw2Fh9PweN2bUTPDSatyme5S
5Jverug9poXUgi73A4n3ZRRLRCfqkNAYs5wZCLv5meNxh8qjr91

- Click on import and you are done!

EDIT: I sent .25 btc to the address via bitbook.biz 25 minutes before they did the 1 satoshi. Do they have a script or something that sends the 1 satoshi to any address that does a transaction, and they check via blockchain? This is ridiculous!

It makes sense to target recently used addresses. The owner of such addresses will be paying attention to the balance so he'll notice the advertisements.

I generated lots of wallets in bit address.org and when it comes to importing them into Multibit it seams the private key is in the wrong format can anyone help please? I only have a mac by the way

Oh my! I hope you didn't send coins to those addresses.

FYI bitcoin private keys come in Wallet Import Format (WIF). There are two types:

- Compressed: These begin with L or K and have 52 characters in em
- Uncompressed: These begin with 5 and have 51 characters.

Do any of the above match what you have??

More details: https://en.bitcoin.it/wiki/Private_key#Base_58_Wallet_Import_format

Of course there will be more surprises down the road. Bitcoin is anything but boring.

At the moment bitcoin clients don't support this but hopefully we will get there in the future. We should get there in the future because it can be done and people want it.

For the moment you can use coinapult.com.

I hear drugs are banned in the US. Why then do Americans consume so much narcotics?

Banned does not mean that people will just stop using it. It means that if you get on the radar of the authorities they may take action against you. But for the most part no one gives a crap what you do in your own home.

I don't even have a computer. I'm one of the people bitcoin is trying to win over to make it more mainstream. I'm not really tech savy. One thing holding bitcoin back is it seems you need to be somewhat tech savy to use them. They recomend you don't keep your coins on a exchange due to hackers. Ok, so I send them to my phones wallet. Ok, now if I lose or break my phone my coins are gone. Not going to walk around with thousands of dollars in bitcoins in my pocket either. Ok, so now they say you need to back up your keys with a flashdrive or external hard drive, computer, or print out a paper wallet. WAAAYYY to many steps for your average user. It really needs a US based coin exchange thats regulated that people would feel safe keeping there coins in a online wallet then transfer small ammounts to there phone.

Ah, then bitcoin is not for you. You don't use computers and you don't trust foreigners. Bitcoin requires, first and foremost, an open mind and a willingness to learn new things.

most update one possible... torrents is appreciated, but direct download would be <3ed

anyway, not this:
http://sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain/bootstrap.dat.torrent/download
since it's uncompressed.
Thanks for any suggestion

Ah well there's a reason for that. An uncompressed torrent allows you to update to a new version of the of torrent from the point at which the previous version ends. So for example it used to 10GB and now it is 13GB. You want to switch to seeding the 13GB version you just have to download 3GB not the full 13GB. Something like that.

Anyway if can't download the uncompressed version use a thin client like Electrum.

I can try, but will it also give me my 0.10btc back?
As for me that is the most important at the moment.

Try it and find out.

edit: Basically if a transaction has not been included in the blockchain it is like it never happened.

And no, it's not about money. I can afford to pay. But I don't want to. I don't want to contribute to a project if 90% of human beings are left stranded at the gate. That looks too much like the current financial and banking system.

I think you'll find the whole bitcoin economy is like this. There are the early adopters who are now like aristocracy and then there's the rest of us.

Suppose someone sent me bitcoins and in my wallet it started showing 'awaiting confirmations'.Can I be sure then that I will get the coins properly?

Actually I want to lease my rig.I want to set the mining for a renter as soon as possible.

Can something go wrong during confirmations?How about after 1 confirmation,can I be sure than?

These days you should wait for at least 1 confirmation. There was a bug that affected unconfirmed transactions so better to be safe than sorry.

I think we'll see it forever in the qt client till there's an update. It's really
no issue except it takes up one the three listed on the main screen, which
is annoying.

Yup, but for me its also 0.10x btc missing now which i wanted to invest.
So losses will add up.

I had high hopes for BTC, also been a supporter for years now, but this is a blow in the face for me.

~~The transaction maleability thing has blown over. I haven't really seen any new reports of it since that first day. Your problem is a wallet stuck in the past~~ Looks like I spoke too soon. Still a problem it seems Sad

.

I suggest you

a) backup the wallet file

b) Use pywallet to remove all offending transactions.

See if everything works now.

ismine is true

This is regarding 1BWxWrPxVcGvYLS4E6kdMEKDmNhPWxtNT6 ?? dumpprivkey also worked for this address?

Do you have an old wallet backup? I suggest creating a backup of your current wallet.dat file and then replacing it with the old backup. Then see if your coins show up. If they don't do the dumpprivkey command for the change address (1frs) again to see whether it shows up using in the old backups.

Any guesstimate at the chance of success a specialist company would have?

Any ball park idea of costs and does anyone know of a trustworthy company? There's a possibility that the wallet could be worth a decent amount of money...

Googled this sometime back. It starts at $300 and goes up from there to thousands of dollars.

Quote from: Racer8 on February 14, 2014, 08:35:07 PM

Not looking good - ismine was false. Dumprivkey obvoiusly did not work either

What about

dumpprivkey 1BWxWrPxVcGvYLS4E6kdMEKDmNhPWxtNT6

after a wallet unlock?

Ok here's the sheet if anyone wants to see it:

https://docs.google.com/spreadsheet/ccc?key=0AkZGioJLkfk4dFFhQndCRXo0cWdsS0U4RnAyTFZsZWc&usp=sharing

Thanks again Nawazish.

So I put all of this into a spreadsheet and this is what I'm getting:

Average BTC per day: 0.0152270741
That comes to: 0.0084594856 per Mh/s assuming your rig mines at a steady 1.8Mh/s

So that's even less than the 0.01 BTC per Mh/s that I read about. Still not bad given the conditions over here. What coin do you mine these days?

Ok. Good. Thanks for this.

Do you think this mobo here will support 4 GPUs?
