I have created many wallets in Electrum. Will create some more and divide my Bitcoins among them.

I will print the seeds, as a backup will print the Address and Private Keys on papers too, cut these papers into two and will store them in a secure manner in different places.

Now - at that point, am I missing some point? I mean at a later time when I put the seed in Electrum on a very different and clean computer that has no clue of the Electrum that I create the seeds, is there any possibility that it would say "you have missing xxxxxxxxxx file, seed can not be recovered" etc?

Actually I tested in a different computer; the seed I created on another computer was recovered in the other unrelated one - so only the seed seems to be enough.

But I would like to make the things exactly correct and be well informed - to avoid any problems in the future. Would backing up seed only would work on any Electrum, on any computer to be recovered?

And - I would like to check the balances with a master private key regularly - I guess this is riskless and harmless? Or would this create another security vulnerability? I plan to store the master private keys in Truecrypt and check the balances on a live USB or CD. Master keys - what risk would these give?

Use the Master Public Key to create watch-only addresses of an offline wallet.

If someone finds your private keys that you've exported you could compromised your entire seed. More insecure would be if they have them and also have your Master Public Key (* you called it Master Private Key <- this doesn't exists yet)

Thanks for the reply.

So - Is there any other way to check the balance of an online address which we do not have access the seed that we store securely elsewhere?

EDIT: OK - It seems to be the Blockchain.info

The seed is the one you need to keep offline. You can take the MPK for that wallet and use it in the online computer to check balance and make unsigned transactions.
