How do you make a good backup for your wallet? Do you just write down the seed and thats it, or is anyone doing anything with private keys? I am using electrum just in case anyone thinks of a good backup solution for this type of wallet.
I also assume that not many people save all their bitcoins in just one wallet. Am I right?
The seed can generate all the private keys, so you just need the seed. It's nice that way because with bitcoin-qt you have to back up all your private keys (which increase over time)
