Yes. Requests is not a mandatory module to be installed. It's only required to get locale and an older version should work fine as well.

Electrum doesn't have to be installed. You're only installing the utility required to upgrade the package and also upgrade the package itself. But as I said, it'll be fine without upgrading as well.

Yeah it will. If you prefer to not install anything, then this is probably the way to go.

You might've misunderstood the entire topic.

The hit with the bounty in Bitcoins was referenced in the show. If this doesn't sound illegal to you, then I'm not sure what jurisdiction you live in. It is fictitious so no government or law enforcement would come after them. I don't expect them to have any impact, no one other than Bitcoiners would care that they referenced Bitcoin in their shows. After all, who doesn't know that Bitcoin exist?

Nothing new, tons of other shows has featured this. Mr Robot for example. It is almost always being used with illegal transactions which doesn't give it a good portrayal.

Not saying that it isn't good; bad publicity is still publicity but I would very much like for it to be portrayed positively instead .

You meant giving the choice to the user to install the app themselves if they want to?

Yeah, you can already do so through your app store. There is no such thing as default Bitcoin wallets; making people use a certain app goes against the ethos of Bitcoin.

No one likes bloatware. This is a terrible idea and I'm not sure if it is even allowed on most mobile service providers.

People won't use Bitcoin unless there is a reason to and most commonly, it would be some incentives from using it which most companies won't have. Forcing Bitcoin on people doesn't bode well for its image nor increase the adoption by any significant amount.

Rather than focusing on getting a paper wallet, try getting an airgapped wallet instead. Paper wallets are not very secure in the sense that it is only a backup method. The main thing that you should be focusing on is the generation and the spending part.

I'll probably just recommend you to search for guides to make an airgapped wallet. You can do so by using a LiveUSB with an OS distribution and just install and generate your wallet completely offline. You can also spend it offline by signing the transaction on that offline device and thus ensuring that the private keys and the seeds are never exposed.

Probably possible. But would be adding much more load on the existing servers.

OP said Pre-Segwit but yep you're right.

Seed phrase extension is available with BIP39.

MyCelium has BIP44(?) derivation path so unless you're using a wallet with the same derivation path, you can't find it.

I don't trust anything that requires the user to go online to generate any addresses. As the browser has to load the script from the website, it'll mean that it is totally possible that the site owner can insert a backdoor or any MITM attacks can happen as well. Browsers are not specifically designed to generate addresses anyways, I would rather just download a desktop wallet and do so myself.

However, if you want to see the script for bitaddress, go here[1]. During the generation, it calls for the CSPRNG function within the browser and salts the entropy with mouse movement as well as other random variables.

Reproducible. Not an issue as Electrum won't run if it is a critical problem.

In your terminal, install pip and then upgrade requests.


Electrum uses requests-2.25.1 but Debian 10 doesn't have that.

I wouldn't install anything sensitive without verifying its authenticity first. Apple doesn't allow sideloading apps and thus you can't validate the binaries before installing it. For Android, at least you can validate the signature before pushing the apk to your phone.

The problem with those apps is that they don't usually contain any malware or exploit but steals the key in a very obscure way such that it is hard to detect without any reports.

Brass will be a better choice than copper as it is more corrosion resistant.

Brass will still corrode more than stainless steel and has a lower melting point and softer. In Jlopp's tests most of the higher rated ones uses stainless steel or titanium except one which used copper and you can see that it corroded quite badly.

Oh, I didn't edit that part. It took me quite some time to demonstrate and get the syntax right.

It's working perfectly. The only part that is not working is getting it to work in the UI.
You don't have to strictly backup your wallet (in the case of Electrum) using the seed phrase. If you want, you can back it up in a method similar to Core using the wallet file encryption with the seed and the addresses all being encrypted in the wallet file.

You can either encrypt the file fully (which is enabled by default) or only encrypt the keys.

It doesn't hurt to just try to open it first.

Aluminium is fairly weak and oxidises. No such thing as fireproof, only fire resistant.

That being said, if you're doing any etching, try to find some forms of alloy. Most non-alloys are fairly soft and have a comparably lower melting point. If the security is of any concern to you, you can probably sandwich two plates of metal together with the seeds facing each other. If not, there are commercially available solutions which are not so eye-catching.

It is not a cold wallet. It is merely a form of backup.

Steganography is not uncommon. You can obviously do so yourself but putting it on a vinyl disk is probably one of the most terrible ideas; expensive and short life span. I'd rather etch mine on a metal, probably cheaper and more durable by far. I really doubt the general population has a working vinyl disk, not even something that can write on it.

Electrum supports mini private key. Casascius's mini keys were 22 characters instead of the usual 30. Electrum will support anything more than 20 if it is valid.

It's simple to actually just do the whole process of obtaining a standard WIF yourself. Just SHA256 it and you'll get an ECDSA private key which can easily be converted into a WIF.

MyCelium is a wallet and coinbase is primarily an exchange. Coinbase can and will collect personal data about you, have certain level of control over your coins as well.

Coinbase also does not offer any sort of discounts for on chain transactions as well. MyCelium, though being less polished, still offers far more security as well as privacy.

It's completely possible, though I'm currently having difficulty doing so but that is on testnet so I'm not too sure about main net.

On your offline computer, go to Help>Console and key in this:


You should get an output with loads of info. And take note of that field.


Generate another receiving address and transfer both the desc and that receiving address to the online Bitcoin Core.


Next, go to your online Bitcoin Core and key in this:

after that,

Use the code below

Afterwhich, you'll have a long string. Copy that and save it to a file and transfer it to the offline computer.



On the offline computer, go to the file and copy the string again. Then go to Bitcoin Core, File>Load PSBT from clipboard.

A dialog will show up with the information, double check that the change address specified is from your offline wallet, the destination is as intended as well as the amount. If everything checks out, press sign TX. Press Copy to clipboard and save it to a file for transfer to your online computer.

After moving it to your online computer, open the file and copy its contents to clipboard. On the online Bitcoin Core, go to File>Load PSBT from clipboard and check it one final time before pressing Broadcast TX.

Personally, I don't think Bitcoin Core is designed for airgapped storage as it doesn't offer master public keys to easily create a watch-only wallet or is the UI that optimized for such a thing as well.
