I'm trying to sell the coins on coinbase.  I already have an account with coinbase.  I'm just not sure how to send to coinbase and what the bitcoin addresses that start with 3 have to do with the transfer.

On an offline computer, I used a copy of bitaddress.org to enter a passphrase of 12 words and the private key and public key were displayed.   I printed that offline, and keep the info safe until now.  Maybe I'm not remembering clearly though, as I went bitaddress.org now and I see nowhere to do what I just said I did!  But I'm confident I have the public and private key.  Just trying to move the coins safely to coinbase.

Guys, could really use your help and expertise here.  I found a paper wallet I made with a 12 word seed from bitaddress.org back in 2018.  It's not got much, but it'll cover some bills.  So I already have a Coinbase account.  What's the safest way to get the paper wallet into Coinbase?  I downloaded Coinbase Wallet on the Apple store, and when I run the app, it asked if I had a 12 word seed.  I thought 'this is too easy' and wondered if they meant a 12 word seed from some other wallet program, not a 12 word seed from bitaddress.org.  Also, from my account on coinbase.com, there is no import paper wallet or load private key option.  And one more thing, the receive address for my coinbase account starts with a 3 and my bitcoin address starts with a 1.  Is there some incompatibility issues I need to be aware of?  Finally, I heard that bitcoin 'forked' once or twice and I might have more coins than just bitcoin??  How's that work for sweeping my paper wallet?

I did leave myself a cryptic message that was supposed to serve as a reminder as to what the transposition was ...  I wrote this message the day I did the transpose, so it stands as the best clue on how to get the bitcoin back.  I believe it jogs my memory on where in the 99 digits the cut occurred, but not sure on how to interpret the message as to what the paste was and where the paste occurred.  But your questions have given me fresh thoughts on how to solve it.

I've tried 2 digit and 1 digit transposes as well.  No luck.  So I believe I cut 3/4/5 consecutive digits somewhere and then inserted 3/4/5 other digits.  The difference possible combinations start to explode towards infinity and I fear I've lost the coin forever.  Does any recovery service exist to write code that tries to recreate all this possibilities?  I know most of the private key, but do I know enough?

I know a fair amount of python and have already attempted this.  Either I'm not good enough at python, python is the wrong tool, or the cut and paste was too big to brute force.

Back in 2013, I got interested in the hype a got a bitcoin from Coinbase.  Thinking I was being extra cautious, I created a "paper dice wallet" by rolling a six-sided dice 99 times per the instructions at bitaddress.org. 

From their website :  An important part of creating a Bitcoin wallet is ensuring the random numbers used to create the wallet are truly random. Physical randomness is better than computer generated pseudo-randomness. The easiest way to generate physical randomness is with dice. To create a Bitcoin private key you only need one six sided die which you roll 99 times. Stopping each time to record the value of the die. When recording the values follow these rules: 1=1, 2=2, 3=3, 4=4, 5=5, 6=0. By doing this you are recording the big random number, your private key, in B6 or base 6 format. You can then enter the 99 character base 6 private key into the text field above and click View Details. You will then see the Bitcoin address associated with your private key. You should also make note of your private key in WIF format since it is more widely used.

So I wrote down the original 99 rolls as 1330540124221 and so forth.  Then, in a stroke (of genius), I transposed some of the digits (i.e. moved three consecutive digits to another location in the string of numbers) to obfuscate them, thinking if some sophisticated attacker were to gain access to my dice rolls, they would be unable to spend them.  Maybe I was too paranoid.   I've forgotten which digits I 'cut and pasted' and how many ( I strongly think its 3 to 5).  I actually kinda remember the area where the cut happened, not the paste.   How screwed am I?  Any chance to recover this bitcoin?

Python script based off script that was shared publicly. 

I've  tried almost all permutaions of 5Juu2CkB3 [EAhBp / NAhBp] EcyH9dypNhDZ8fXgh6RQwwbo5 [ueBa6 / pdBa6 / sdBa6].  No luck.

Changed it to DZ8fX and no luck.

Well then now I have:

5Juu2CkB3EAhBpEcyH9dypNhPetergh6RQwwbo5ueBa6------E



I bruteforced all keys associated with this pattern.  This is not correct.  I suspect the Peter needs to be changed to something else.

Is there an easy way to follow when they make a post or reply to a thread?

The signal to noise ratio on Bitcointalk.org is low.  I'd like to parse out the noise and follow the movers and shakers in the nascent economy of Bitcoin.  Suggestions on who to listen more closely to?

For the sake of the argument, let's say I have reason to believe my Windows computer is compromised with trojans, keyloggers, screenshot capturers, etc.  Is there an way for me to create a secure paper wallet on that computer?  Unplug the internet cord during the creation?  But my coins are on Coinbase.  So how do I securely get my BTCs from Coinbase to paper wallet.  I know they have that option on the website, but I'd have to be connected to the internet to generate it.  I'm not familiar with LiveCDs and Linux so ...

Also, once I have my paper wallet secured, and in X years when BTC are worth Y, how do I redeem them from paper back into the system?
