What exactly is "grandma style"?

something your grandmother would understand, even though she's demented and not very smart.

Fellas!

 Take a look at this:

 Wallet in the Cloud - Keeping your Bitcoins encrypted and saved into the Cloud!
 http://forum.bitcoin.org/index.php?topic=22386.0

 What do you guys think about my solution?!

 It is really easy to do by everybody...  

 And it can be easily changed, or used with a USB pendrive instead a Cloud environment...

Cheers!

wouldn't it just be easier to keep a computer just for bitcoins with nothing but bitcoins necessities on it, since you will be a full time bitcoin trader. Don't open anything on that computer or even install anything beyond the bitcoin client and a miner. do your dealing on the less secure computer but send only from the secure one..?

Create a truecrypt volume and insert the wallet.dat file in that volume. Make sure the volume has only a few megs, then copy it to your dropbox account so you can have it anywhere.

what's right/wrong here?

1) a wallet starts with 1 address, a public key you can see in the client, and give to the world, and a private key hidden in a wallet.dat file
2) from time to time a wallet generates a new address for various reasons most of us dont care about
3) is this new address just a public key associated with your original wallet.dat private key, or is it a KEYPAIR ( a public address that is associated with a NEW additional private address now stored with your old private keys in wallet.dat)

I think wallet.dat holds the private keys for all the public keys associated, and thus controls the btc associated with those public addresses. If someone else also has the private key they can spend the coins too.

afaik....

1) 10 addresses
2) hm, the client generates the addresses, not the wallet.
3) The second thing. So don't back up your old wallet, generate new addresses, fill them with coins and expect the backed-up wallet to access these (am I making sense?)

Hello,

using two wallets is really a great thing for security, ... but:

** Poll: Who is really doing so? **

Be honest. How many of us really use two wallets?
One for daily buying and selling. One for saving.

2% - 5% of the people in the forum? Maximum.

Well, you got me thinking. I guess I'll start using two wallets also.

This is not feasible for practical applications like micropayments (or even normal sized payments).

Another newb question if I may:

What are the chances that the fresh OS run off a Live CD will get a trojan in the time needed to d/l the bitcoin client and create the safe wallet?

Am I getting insanely paranoid?

thanks
