I have now come to the conclusion that there is nothing that I can do to make a secure paper wallet. Surely any combination of numbers/letters/words etc will be guessed by some supercomputer sometime?
Not at all. Combinations grow exponentially large, much too big for supercomputers. Flip a coin 128 times, you have 2^128. That's about 340 trillion trillion trillion combinations, Each of which would have to be checked by doing a complete Sha256 hash. No computer could do it in any mortal time frame. Roughly a billion seconds ago, Jesus walked the earth. So do you think my 64 dice rolls followed by a few words is sufficient? , a person could bruteforce your 64 dice rolls and a few words in a few months or even days. And are you sure you can spend the time to type those 64 letters and a few words? You can easily forget it. -ranochigo 64 dice rolls is 6^64. that's on the order of 2^160. You can't brute force it even if you had a million billion years. It has nothing to do with opinions! That's this many combinations: 1461501637330902918203684832716300000000000000000 Anyone who says you can brute-force that doesn't realize how BIG that really is. Imagine, you are really urgent for a few BTC, do you take your time to type the 64 characters and few words? Wouldn't it be better if you scan your paper wallet and put in a few letters and get your BTC instantly? Even if it is that secure, you are sure to get a few letters wrong in the 64letters and a few words, you might not even be able to remember it. -ranochigo |

regulation will kill bitcoin for sure. so no.
You just cannot kill bitcoin in a specific country since it is peer to peer. Unless the government completely cut of internet access. Bitcoin can never get regulations. -ranochigo |

So you really think it would be safer to generate keys by using 'the moving dots' on bitaddress.org etc? In your opinion, is that the safest way?
I would also love to hear someone else's opinion on this.
Unless you can manipulate someone's mouse strokes perfectly for 200 times, then you can hack it. This is theoretically impossible on a computer which will never access the internet. Even if the mouse strokes are recorded, the attacker will not be able to access the mouse stroke recorded. -ranochigo |

It isn't profitable, you need to run the computer 24/7 and captcha solving services are either too expensive or cannot solve those captchas.

I did a LOT of research before making my wallets. I often read that those paper wallet generators could be rigged (can't remember what the correct term is but you know what I mean  ) and was lead to believe that the way I did it was the most secure way. [/quote] That isn't 100% true. Yes its true that paper wallet generators can be rigged, you can use them on a offline computer by downloading the codes and run it on the offline computer. To prevent the possibility of it being rigged, the best way is to manually review the codes. Try not to use those online wallet generators. -ranochigo |

Any computer connected to the internet can be attacked. If you have enough to worry about get a laptop and never connect it to the internet.
Have there been known instances of attackers successfully bruteforcing keys made using a dice roll? Do you mean dice roll by the result of (1-9)? If that is so, there is a lot of cases which the wallet was compromised. -ranochigo Is that the case no matter how many times the dice has been rolled? Also I added a few words after the numbers when generating my keys. Would that not make it harder for it to be bruteforced? There is always a possibility, even if you add alot of letters, its not enough. Try generating a paper wallet, I believe alot of those paper wallet generators generates your privatekey using your mouse keystroke, its more random. -ranochigo |

I bought a cheap tablet solely for the purpose of generating addresses & making paper wallets. I did this offline & that tablet will never again be connected to the internet. I think that's about as safe as you can get. I would think twice before doing this. There was some problem in the RNG on android, it allowed attackers to brute force the private key easily. It might be possible for another problem to surface, use an offline computer which will and have not connected to the internet. -ranochigo I didn't use a RNG. I rolled dice & then put the resulting number in as a brainwallet passphrase. Does that mean my paper wallets are safe or are they still at risk due to this RNG problem on Android? That is worst, brainwallet isn't the most secure, attackers can bruteforce the result of your dice number. If sucessful, everything will be stolen. -ranochigo Have there been known instances of attackers successfully bruteforcing keys made using a dice roll? Do you mean dice roll by the result of (1-9)?

too bad almost no one offer signature campaign for jr.member
Scratchticket only give you a few satoshi (21k satoshi) but you can play in their site and if you lucky, you can get more satoshi
wait for 1 month and you'll become member, and then join profitable signature campaign
and you maybe ask me, what should i do now, i'm still jr. member?
i recommend you to join free distribution or giveaway in alt-coin section
Most altcoins are scams or pump and dump scheme which have low values, you cannot earn much more than the JR.Member signature campaigns. -ranochigo |

when you find one, let me know. i'm not even a jr member yet! working on it...  You'll get to a member status veru quick. Just find some topick where you can write everything you know, go to he off-topic, you can find something there. Cheers! Activity only increases 14 every two weeks, it would take some time for him. |

How? And how can someone see it?
I think nearly all of the wallets includes the feature of adding a message to the transaction. Note that you cannot remove it, it will be permanent to the blockchain and everyone can see it. -ranochigo You are mistaken. This is not correct. None of the wallets provide any user interface for adding messages into the blockchain. I can include a note in the blockchain.info transaction. I don't get what you mean. That is not "permanent in the blockchain". That is a service provided by the blockchain.info company. If you use their wallet, then they let you create a message that they store in their own database and they display on their website. This is not a feature of bitcoin, nor of the actual blockchain. You cannot create those messages with any wallet except blockchain.info Oh I see, sorry for the confusion, thanks for clearing that up. -ranochigo |

Its really too late to join in. The difficulty is far too high, electrical and hardware cost have to be included. A lot of ASIC companies take a long time to ship, by the time the hardware is shipped, you can't even ROI.

ANXPRO is probably one of the best. I am currently verifying my information there, but so far, so good. There is good security and professional looking interface.

Newbie here.,.
I've dabbled with bitcoin a while back and i used an offline wallet. Shit took forever to download and set up and i only had .00001 btc and i tried mining but my computer is shit so i didn't get anything.
I'm think of getting back into bitcoin and doing pool mining.
My question is it worth it wasting time to create an offline wallet and download all those blocks again? i know offline wallets are more secure though..
Should i go with an online wallet like coinbase since it's much faster but i know coinbase got fees and shit and money is not that safe being store on someone's else server..
You do not actually need to download blocks to create an offline wallet, use a paper wallet service and generate it on a offline computer. Coinbase do not need fees for transactions with 0.001 and above. Put a small amount in coinbase and most of the BTC in offline wallet. -ranochigo |
