Cold storage advice

Just use Electrum (from electrum.org) on a safe computer (no Windows).

Or if you prefer the longer explanation.

My opinion is you should understand how computer security works before to do anything.

Some important things:

  • Your keys and passwords might get written in the swap file/partition on your hard drive. Don't use swap or encrypt it.
  • Your printer may have memory (hard drive).
  • Your printed documents are saved on your hard drive and then deleted not securely (if you don't use non-HDD system, like Live Linux system from a CD/DVD)
  • Your USB devices may have malware installed in their inner computer (not in the visible from the outside filesystem, it's not visible by the external anti-virus software).
  • Make backup on paper (seed) before you load your wallet with coins. Don't lose the paper backup.

Do not use (only) flash memory (SSD drives, hardware wallets, USB flash drives) for your precious private keys!

Flash memory is not a reliable medium for archives. Especially when there is no regular power. I have personal experience with usb flash drive not powered for weeks - one file became corrupted . (Read more here: Archiving private keys - TLDR version. ) You should always back up on paper and other mediums. Flash memory is prone to failure if it is not powered for weeks or more and if there are ionizing radiation When you write your precious private keys you should use technologies like Parchive and ZFS . And make several copies of your files. It's OK if you use your USB flash drive for another backup, but don't rely on it! Always back up on DVDs (even small files!), paper and online (after encryption with CPU and RAM intensive key derivative function like scrypt). Here is example of using the scrypt utility: $ sudo apt-get install scrypt $ scrypt enc -M 1073741824 -t 200 secret.txt encrypted.scrypt Do not use default values of "-M" and "-t", they...

Archiving private keys - TLDR version

0. Make multiple encrypted copies. On DVDs (they are better than CDs and Blu-Ray discs; DVD+R are better than DVD-R), paper, cloud services like DropBox, OneDrive, Google Drive, e-mail it to yourself and to your friends, use P2P storage services like MaidSafe, Storj and Sia , etc. 1. Use proper font when printing PGP encrypted keys on paper. 2. Flash memory (SSD, USB flash drives, hardware wallets) is less reliable when not powered regularly (i.e. every week). 3. Use error correction methods like Parchive and ZFS. 4. Print on paper or store on digital media only encrypted data. 5. Your encryption software should use CPU/RAM-intensive KDF (i.e. scrypt with secure options - do not use defaults! ). First, encrypt with scrypt and then encrypt it again with PGP (using different password!) in ASCII armor mode before print it (other methods like QR codes may not be reliable as multiple copies of the PGP ASCII armor). Do not use the same password for the PGP because it's easy to brute...

"The Uncensored Hidden Wiki" fake replica!

Image
I found out that there is a fake version of "The Uncensored Hidden Wiki". On the fake version some links are changed with fake websites. I suppose they are trying to steal your login credentials. I compared the "Financial services" pages on both wikis and found out that they changed the URL of the "Hidden Answers". However, the fake replica of "Hidden Answers" don't work at the moment.   Genuine (supposedly): http://gxamjbnu7uknahng.*****/wiki/index.php/Financial_Services Fake: http://uhwiki36pbooodfj.*****/wiki/index.php/Financial_Services   Please note that I do not guarantee which of the above URLs is "genuine" and don't assume that any of them are "safe". Maybe both of them are "fake", I don't know. Here are some examples of differences: Screenshots are from Meld . Visit "The Uncensored Hidden Wiki" or any other *.onion website at your own risk. I do not endorse and do not reco...
