Good to hear this message OP its look like you make knowledge and find an answer to your question in some altcoin their a paper generator waller that you can find regarding to your question I know in the first place you generate wallet private key will there and you need to save.

Thank you for your replies.

I've forgotten everything I knew about blockchain, coins and wallets! My head is spinning now!

After going through all the bumph in my password manager it turns out I've exchanged everything into BTC, except 649 MUSIC.

I'm not going to use bitaddress.org and go for the suggested Electrum. The BAT can carry on dropping into the Uphold wallet that the Brave Browser setup until something exciting happens.

Setting up a paper wallet with Electrum...
I use Linux so I've downloaded the Python sources, transferred the package to an offline computer and run it without installing.
Then, created a standard wallet, created a new seed (segwit), written the seed down and I didn't encrypt my wallet keys with a password.

I am assuming that for as long as Electrum is around then the seed is all I need. Id' like to jot down the other keys too.

This is where I get confused! I thought you have a private key, a public key and a hash of the public that creates the bitcoin address and that it's the bitcoin address you give out if you want someone to send you BTC.

I have found the "Master Public Key" but don't see a private key or bitcoin address. I've clicked on View-Addresses and I get a list of "receiving" and "change" addresses. I guess you get a bunch of private keys in a wallet and I am now looking at them.

I just want one private key along with the related public key and Bitcoin address.

How can I get these keys/addresses from Electrum?

Thanks for the help guys! I can't believe how much I've forgotten! Like, for instance, the fact that I exchanged all my coins!!

Are you sure to store paper wallet safely. I think the paper wallet only makes it more difficult for you to keep your balance compared to online. We have to think about that Bitcoin and other cryptocurrency digital assets whose systems are always being upgraded.

You doning it quite correct way. To simplify things, convert shitcoins to one coin BTC, then one paper wallet or split it to couple BTC paper wallets for extra security (bad luck mostly from someone else using same address, almost impossible but still why risk ).

Bitaddress is relatively trusted, but it doesn't currently support segwit. There is an offline segwit address generator. You can test these individually. But again, with one Extended Private Key using Electrum, or just the usual 12 word seed phrase, you have plenty of addresses that you can generate. By default, the app shows you 20, but you can make it show the next one hundred or next one thousand addresses in the sequence.

It's deterministic, so the addresses will always be the same if you use the same exact 12 word seed.

Download the QT wallets from the github page of the coin itself.
There are many clones of wallets in the wild and downloading even one incorrect can make your system susceptible.

Make a text file with all the private keys of the remaining small coins and then encrypt the text file with notepad++ and nppcrypt.
This will provide an extra layer of protection.

It's pretty hard to trust all of these generators. Even if you run it offline, there is no guarantee that a vulnerability is added to the random number generator.
Everything rests on the credibility of the developer and the hope that someone reviewed code. Therefore, only electrum or core.
Something like this: https://www.theguardian.com/technology/2013/aug/15/google-android-bitcoin-securerandom-vulnerability
This situation looks like an accident, but also someone can bring vulnerability intentionally.

Paper wallet is a great low-tech way of securing your funds and there is some good advice above - make sure you're doing this offline (getting an address from a website is not safe), make sure you print it on a secure printer (not in a office where other users could access your print queue or printer document history) etc. Also make a solid plan on how you'll store those paper wallets. Unfortunately they can be vulnerable to pretty much everything - fire, water, theft, even UV light or just regular environmental conditions depending on how you printed them.

I second this, Electrum is an open-source software verified by many people, and you can verify that the installation files that you downloaded are indeed the original files created by the developer. It's much much more secure than going to some website that generated a private key for you, and since OP wants to put all his BTC savings there, using something like bitaddress is just an unnecessary risk.

Electrum is even better than paper wallet, because you can create multiple backups on different mediums - you'll write down a seed on paper, save the wallet on a flash drive, and can optionally memorize the whole seed.

Please make sure that you download locally the scrips from bitaddress.org and run them in a safe environment; you don't want others also get those private keys. Or get a mnemonic phrase for Electrum (safely).

For XMR the command line wallet creates a mnemonic phrase which you can easily backup and you can say you have a paper wallet.

Check each altcoin to see if they have a paper wallet generator on their own site. You could also look for some vanity wallet generators that are compatible with your coins.

In the worst case scenario, you could download the original wallet, probably a Core-QT wallet for those altcoins and use that to generate addresses and dump the private keys to make your own paper wallet.

For BTC, I'd recommend you try Electrum, download it from the official website, make a new wallet and write down the seed phrase on paper. Get the extended public key or something, and start over, you'll end up with a watch-only wallet.

When you first launch it, you'll get maybe 20 addresses, send a little bit to the first one as a test. Once that confirms, you can start sending to the other addresses.


For the other coins, depending on how long you think those coins will survive, you could save them or trade them (they are on an exchange right) then withdraw the BTC. Of those you mention, I probably would keep only BTC, BAT and maybe XMR. The rest I would trade and withdraw as BTC.

I've got a bunch of coins kept in wallets at an exchange and I want to move them all to offline paper wallets.

Looking at my records I seem to have BTC, BAT, BTG, PASC, MUSIC, ELLA and XMR.

I've been to bitaddress.org, created a wallet and printed it. Before I transfer my BTC I wanted to double check that this is a legit wallet generator... most of my $$$$ is BTC.

How about the other coins? Most are low balances. I think MUSIC is now worthless, but nonetheless, I might ask well keep them!

Thanks
