I own a mycelium entropy and do not have a printer with a USB port to print out the paper wallets.
Does anyone know how to print out using it on the USB port? I gave tried...but with no luck.

I have one but I haven't used it in a long time. When you plug it into the USB port, it generates an image file of a paper wallet. You just print that. You might have to tell the computer that it is a storage device.

BTW, plugging that device into a printer is absolutely the safest and most convenient way to make a paper wallet.

Tried again...and you were right..it created a new image each time with a new wallet! Thanks..

For some reason was thinking more than one image had to be created. Cheers

The image file does come up...but it looks like the same one all the time

Sorry, I don't know what might be wrong. Here is a copy of the user manual: https://www.mycelium.com/assets/entropy/me.html

Thanks! I am also looking to buy another Mycelium if anyone has one for sale

I did not use Mycelium entropy before but as I see it, using Mycelium Entropy without being connected directly to the printer will defeat the purpose of this USB. Mycelium entropy was designed to produce a randomly generated keypair when it is connected directly to the USB port of the printer. Also, the generated key pair is not stored in the USB, so when device has been ejected the key pair is automatically lost, which makes it ideal to produce your private and public to ensure that the keys are not compromised.

Also, where can I get the best and safest paper wallet generated software?

So far this is the most accurate guide I have seen on the internet.

[2] https://github.com/bitcoinbook/bitcoinbook/blob/develop/ch04.asciidoc - paper wallet generation is found on the last page.

Thanks for the info...

But i could still use it on a cold computer that is never connected online

Mycelium entropy is a pretty dead relic. It is definitely useful for generating paper wallets but it wouldn't generate any segwit wallets and paper wallets are by design, pretty troublesome to use. I would just keep it as an artifact and buy a hardware wallet instead.

Using a linux live CD with a printer is fairly secure (though slightly more troublesome than a Mycelium entropy). I would recommend you to download it from github instead of just going to the webpage; it's quite easy for the site owner to break the entropy and produce less than secure addresses and it has already happened.

At least with a github repository, you can review the changes that's made to the code. Try https://github.com/pointbiz/bitaddress.org.

If you just want to generate and print paper wallet, there are many options available.

For safety, it's recommended to save the whole page and disconnect from internet to generate a new wallet. Or for the peace of your mind you can even copy them to a non connected device to generate a wallet and print them.

Saving a page and running it later offline is equal to running a software with unverified source code. You could try to verify it yourself of course, but you need to be a Javascript expert and still there's a chance to miss the backdoor code.

The correct way is to launch a live OS, create some private key - address pairs with a wallet like Core or Electrum, and print them out as QR codes. You won't have those fancy designs, but it's much more secure. You can also create an Electrum wallet, write down the seed with pen and paper and print out as many addresses as you need - this will avoid the risk of exposing your private keys to an untrusted printer.

Great 💡

If you want to generate wallet with some prefix, you can use vanitygen offline.

Thanks..I am a bit leary of any online generated on or off..but will look into this.

Are there any new paper wallet generated hardware devices like the Mycelium entropy?
