Fixed that for you.

All cracked versions of windows have backdoors built in.
Bypassing all necessary license checks in a software as complicated as windows is not an easy task. This takes a lot of time and resources.

Anyone thinking that they are doing this for the good of all or because of the reputation in the community, is just blatantly naive.
In fact, most cracked software is infected with some kind of backdoor or malware in general. Using a cracked/pirated OS is one of the most dangerous thing you can do regarding information security.

If you can't afford to buy a windows license, just switch to linux. You'll do your privacy a favor.

Security-wise there is no difference between copying a private key and having the mnemonic code displayed / generated somewhere on the computer.

Theoretically that's true, because there is a lot of 'dumb malware' which doesn't even compromise the system properly, but instead just acts like a clipping board malware for example.
But if you look at the security itself, this wouldn't change much.

And electrum also allows to copy single private keys.




They aren't discouraged.
Paper wallets are secure if generated properly. Regardless of how you generate the private key (either randomly or by deriving it from a seed).




There is no sense in generating the desktop wallet offline if you are going to use it on an online computer.
This makes sense when creating a paper wallet, but has no advantage when installing / initializing a desktop wallet.




Just because it is a lightweight wallet, this does not mean that the security affected in any way.
You could theoretically receive wrong information regarding transactions. But the security of your funds is not affected.

Not only with the numbers.

If you closely look at the the thread:

While a normal thread with 3 pages would look like:

The arrows («) are written from right to left too (« --> »).

Generally, it works with each characters.
But if you write your normal english chars, it sets the direction from left to right automatically. Therefore you can't inverse the usual letter this way.

If you are using a desktop wallet (which electrum is), you are automatically dealing with private keys.
Well, to be more precise.. the software you are using is dealing with private keys. And that's already enough to be at risk if your computers gets infected with malware.

Any wallet you are using (which has the ability to send BTC) has to use private keys to sign transactions.
It doesn't matter whether you are importing private keys or whether you are using a mnemonic code and let the wallet handle everything else.
As long as the information is available, there is a risk.

test.
Will be deleted.

Thread has been used to check how the forum behaves with arabic letters:

My guess would be that there is an arabic letter at the end which tells the software to write/read from right to left instead of the 'western' way from left to right.
Then, when the software parses and displays that topic, everything added to the end (the pages of the thread) will be written from right to left, resulting in exactly this.

That's obviously just a guess from me, but that bugs occurs quite often in different places where the input isn't sanitized well enough.  


Edit: The question mark definitely is the arabic version of the question mark. So the above written would definitely make sense here.

Edit2: It definitely is the question mark. I just created a new thread (title: "test؟") with the arabic question mark at the end and filled it with junk to reach 2 pages. It exactly behaves like the thread shown in the OP:

There is no (known) risk to a hardware wallet.
And if there would be a risk, it would apply to every OS.

I didn't mention anywhere that the cryptocurrencies stored on a hardware wallet should be the reason upgrade the OS.
It has been more of a general advice, not related to hardware wallets at all.




I fully agree with that.




The operative word here is some.
The majority of the introduced security features make quite a big difference and are by far not negligible. 

It is out of the question that Win10 is more secure than Win7.


If you value your privacy, don't use windows at all.
If you don't value your privacy that much, you can as well use Win10 which offers better security overall.




That's usually the first thing i do. But since a lot of people either don't want to get used to a new OS/new software or rely on windows software too much, the only option for them would be to upgrade to the newer version of Windows.

I also wouldn't say linux is better in 'every way possible'.
For me, the upsides of linux highly outweigh the downsides when compared to windows. But each person has to decide that for him/herself.

If people don't want to switch to linux (which is understandable imo), then they should at least upgrade to Win10.
Win7 misses security features and soon won't receive any security updates anymore (End of Life reached in less than a month).




He himself can't stay protected at all.
It is his IT department which keeps him secure (if at all).

1) According to several internet resources, he is not allowed to use any windows OS newer than XP due to the missing certification from the FSTEC which is required for an OS to be used in such a position.
2) They are working on an own OS called 'Astra Linux' which most probably will replace his ancient OS
3) Who knows whether he really uses this computer to access the internet.
4) Who knows whether he hasn't been infected already (The IT department might just do daily backups and restore his PC without making things like that official)
5) I doubt there aren't good security mechanisms in place (Firewall, IDS/IPS, etc..) which would stop any threat entering their Network, way before it could even reach his computer.

He probably can stay pretty safe using his ancient computer due to their network security. But in the end.. it is just dumb.
However, the real security measurements which protect his computer are definitely not the OS itself (regardless of which OS he is using) and neither any software installed on his computer (random AV etc.).

An attacker would not try to enter his computer, once in their network. I am sure that there are way more interesting targets than the XP of Putin.
But i also believe, if one enters their network.. it would be extremely easy to get access to his computer.

Since the passphrase is 'just' an additional layer and not the only thing which secures your wallet, it doesn't have to be too secure.
However, whenever choosing a password remember that length beats complexity.

Instead of adding those non-standard characters which are very error prone, especially since they can't be entered using a keyboard, just add a few more characters while not using such characters or not even special characters and your password will be more secure than a very complex - but a few chars shorter - one.

The overall strength needed for your password depends on your threat model.
If no person will ever be with your hardware wallet for more than a few minutes and you can be sure that you will always detect whether your device got stolen within a short timeframe with the ability to recover your funds using a backup, it doesn't have to bee too strong.
If - on the other hand - it always will take a few months or even longer until you realize that your HW got stolen or to be able to recover your funds using a backup, i'd rather use a strong password instead of a semi-strong one.

Windows 7 is outdated for a long time now. It is missing a ton of security features which are built into Win10.
You should switch to Win10 as fast as you can.

Note that the upgrade to windows 10 is still completely free.
So, just backup all of your important data and upgrade it via the "Windows 10 Update Assistant". This is an official tool from Microsoft.
And Win10 will accept your licence key from Win7 without any hassle.

No one with even the slightest sense for security should continue to use Windows 7.

Mycelium (android) has been updated on 23.12.2019. I know that this was 3 days after your post, but the update before that day was the 12.12.2019, roughly 1 week before your post.

Mycelium is neither outdated nor insecure in any way.

Might want to elaborate what exactly makes it an insecure wallet? Any vulnerabilities? Any flaw in their concept?
Anything which actually makes one believe that this wallet is less secure than other open source mobile wallets? I don't see anything indicating this.

This depends on the reason you want to operate a full node.

There are a lot of guides available online on how to set up a full node. Following them and setting up a node is not that hard.
But the question is what do you want to achieve with that ?

If you need access to all transactions because you are developing something (e.g. a blockchain explorer), then you need to index all transactions (txindex=1).
If you just want to use it as a wallet without relying on any 3rd party, using the pruned mode is enough (takes less space).


So, if you can tell us more about what you want to do with your node and how much disk space you have available, we can help you way more precisely on how to set it up.

Check the directory for the executable and run it using:

Replace NAME with the name of the executable and ... with the path you want to use (e.g. the one proposed by LoyceV to test).


Regarding your issue.. it definitely seems like a permission issue or a bug.
How did you install core ?
Did you already try to start it via the console and giving it the datadir path via the parameter (i guess you didn't yet?) You might want to try that out.
Also could you give us the output of the directory you are trying to use (using ls -al inside of /media/asus/multimedia) ?
Btw, how is your external drive formatted ? Which format did you use ?

The first step would be to scan your system with any somewhat good Anti virus tool.
But chances are high that it won't find your malware.

So the only way to be completely sure that your PC is clean and no longer compromised in any way, is to reinstall your OS.
Make a backup of all of your important files and format your hard drive. Then reinstall your OS.

And please.. please do NOT use any form of cracked operating system / windows. They are always infected with malware and backdoors.

You don't need to create a new wallet every time.
You just keep your wallet (the software or hardware which holds your private keys) and give each client a new address to send the BTC to.
All of these addresses will be part of your (one) wallet.




You can't add a 'memo' when sending a transaction.
Any kind of 'memo' is just client-sided inside of your wallet. This won't be transacted via the network and therefore the receipent will not see it in any way.


The best simply is to create a new address for each payment. And if its too late for that, to request a signed message proofing ownership.

That's not what OP asked for.
The question was not how you would create a paper wallet, but how to transfer coins from an already existing one.




Yes, if nothing severe happens (i.e. some kind of vulnerability exploit), they will continue to be supported.
And if something like that would happen, this would lead to way bigger problems for the whole network and its users than just your paper wallet.

If you still want to transfer your funds, make sure to do so on a safe device.
The more coins you have on this paper wallet, the more paranoid you should be when typing that private key into a software/computer.

This doesn't just apply to electrum, but to every software wallet as lont as it is not completely offline - cold storage.

There are quite a few wallets which have some security vulnerabilities and therefore are less secure than electrum.
The 'problem' with electrum is, that it is one of the most used wallet and therefore is an attractive goal for phishing campaigns.

If you keep your software and OS up-to-date and use your brain properly, the chance of losing money is extremely low.

Before buying bitcoin, please make sure you know how wallets work and what determines their security.
Read about the basics of bitcoin and its storage and the most common scams (e.g. never buy private keys or let anyone else create a wallet for you).

Use an well known exchange which is accessible from your country and don't buy privatly from people without and middlemen or if you trust them enough.


Whenever you are not sure about something, stop what you are doing and consult this forum before making any mistakes which might lead to a loss of funds.

Mycelium does not only support nested segwit, but native segwit too.

I also don't really get your "security" column. What's your difference between 'seed' and 'seed key'.
With mycelium, you get a mnemonic code to backup - the current standard.

Additionally, every mobile wallet can be recovered using the wallet file. You just need to access it.


What you define as 'security' should be better called 'backup'.
You didn't include anything regarding the security of the wallet at all (e.g. pin code protection, how easy to circumvent, etc..).

May sound rude, but .. it is his own fault.

How can someone download binaries from a website and run them without verifying the signature of the file ?
And then continuing to store 7k $ on it.. That's just dumb.

People are told to verify signatures all the time. Spend 1 hour on this forum and you already read multiple posts telling how crucial it is  to verify the signature of the downloaded wallet before running it.

Really ?..



Using your closed source wallet without any features is dangerous.



Please define 'main chain'.
Do segwit transactions not take place on the 'main chain' ? Please elaborate. I'd like to hear more about that.



So.. if i close my browser tab you 'close the app' ?
Please explain your session handling. What holds me back from closing the browser, then accessing the wallet again using the same identifier (cookie) ?


The answers you give to the mentioned questions make me suspicious.
It doesn't seem that you are experienced with bitcoin / securing web applications.


So.. whether you have an malicious intent or not.. it is dangerous to use your wallet.
Closed source. Weird answers which show knowledge below average regarding important topics. No security audits.

I would suggest to not use that wallet. It doesn't offer any features - in fact it is missing a lot of necessary features - and its security can not be estimated.
