Topic: Where do you keep your bitcoins? - page 2. (Read 6686 times)

Don't forget the risk of theft. Backups won't help if your coins get spent. Best to split off some of your coins to long term savings, transfer them to a separate wallet, securely back up that wallet, and securely delete it. Unfortunately this isn't easy with the current client.

heh... this may be Gold's only advantage:

A fool and his gold are soon parted, But a fool and bitcoins can part accidentally.

on second thought... maybe that's advantage: bitcoin? Finally some effective evolutionary pressure for intelligence and attention to typing.

Don't put all your eggs in one basket. Even if you are methodical about backing up your bitcoin wallet file, it might not hurt to have a few coins elsewhere (e.g. MyBitcoin). Spread the risk.

Also, consider using more than one bitcoin wallet on your computer. Otherwise, if you make a typo and accidentally send 1234 bitcoins instead of 0.1234 bitcoins, you've lost everything.

This is what I would be using

1.) Bitcoin client saves coin to wallet.dat on encrypted hard drive.  {1 copy}
2.) Script saves this file every few minutes to 2 truecrypt files (TC1 & TC2) the script is set to copy twice and hold the previous copy for redundancy. Truecrypt with full encryption options key files and passwords. Keyfiles are unique for each and stored in a keyfile library. {9 copies}
3.) TC1 is saved to a dropbox sync along with keyfile for TC2
4.) TC2 is saved to a jumpdrive stored in fire proof/resistant vault at home with keyfile for TC1

level 1 failure -
1- CPU lost/stolen, I have the data secure on dropbox and on the USB drive in my home vault.
2- dropbox lost/stolen - usb storage and CPU still working.
3- USB storage lost/stolen - dropbox and CPU still running.
4- keyfile library lost/stolen - backup keys restored from dropbox locations and usb drive.

I could go on listing how far down I would have to go before the data is non recoverable. but this should give you a basic setup for a SECURE way to store your BTC with >= US Federal levels of redundancy. If you wanted to backup to past versions you would just need to rename the files on dropbox and the usb storage with the date. then your exceeding US FED standards (they dont require internal encryption. I also used to work computers at a bank, what a pain)

Exactly.  Some people use dropbox to not just back up but to replicate to other systems, including laptops or mobiles.   Do you really want your unencrypted wallet.dat replicated like that?

I keep my coins (such as they are) in my client's wallet, with an encrypted backup on an external drive. If it comes to a point where I actually have significant assets in BTC, I'll also keep that wallet in my dropbox in an encrypted volume.

I follow the 3-2-1 rule of data backup:

3 copies,
2 local,
1 off-site (cloud).

If you want any kind of assurance, it's best to hold yourself responsible rather than a fairly new internet entity.  I don't know anything about mybitcoin.com, it's probably fine, but by keeping them in the client and backing them up myself I know who to blame when something goes wrong.

Yes - a web service is an okay middle man but long term, I'd rather have control of my coins than a website.

So both of you are suggesting using the client to store the coins (then backing up accordingly), not a web service?

I currently have all my bitcoins in the client, and my wallet.dat is continuously backed up via dropbox, which means it's copied to all my devices I run dropbox on, as well as accessible on their website.  Oh, and I'd have to lose two disks at once for me to lose any data on my main machine.

If you want to try out dropbox, use this link and we'll both get some extra space for free.

Regardless, back up your wallet.dat somehow: usb drive, another computer, an online service, or some combination.  It's not necessary to do continuous backups like I do since your wallet has 100ish pre-generated keys, but after you go through your keys and have to generate a new chuck of them, you need to backup again.  Hopefully someone else can clue you in on how to tell when that happens.

Encrypted backups of wallet.dat are the best, in most people's opinions, and if you email them to yourself and keep a copy on a thumbdrive you should be good. Just remember to backup frequently.

As one collects more bitcoins, where do you keep them? Currently all my bitcoins are at mybitcoin.com, but what happens if this site goes down? is it better to send all the bitcoins to your bitcoin client? then what happens if your computer crashes?

So, where does the "smart" guy keep his bitcoins? (what are the best practices for having hundreds, or thousands of bitcoins?)
