[python3 -m pip install --user]

Hi

I just start using Linux (Mint 20.1 Cinnamon) i am newby in Linux and have no coding knowledge.
I went to electrum.org and followed instruction for Installation from Python sources. It works as Appimage and by running without installation but not installing from python as described below.

Code:

 1. Install dependencies:	sudo apt-get install python3-pyqt5 libsecp256k1-0 python3-cryptography
2. Download package:	wget https://download.electrum.org/4.1.4/Electrum-4.1.4.tar.gz
3. Verify signatures:	wget https://download.electrum.org/4.1.4/Electrum-4.1.4.tar.gz.ThomasV.asc
4. gpg --verify Electrum-4.1.4.tar.gz.ThomasV.asc Electrum-4.1.4.tar.gz
5. wget https://download.electrum.org/4.1.4/Electrum-4.1.4.tar.gz.sombernight_releasekey.asc
6. gpg --verify Electrum-4.1.4.tar.gz.sombernight_releasekey.asc Electrum-4.1.4.tar.gz
7. Run without installing:	tar -xvf Electrum-4.1.4.tar.gz
8. python3 Electrum-4.1.4/run_electrum
9. Install with PIP:	sudo apt-get install python3-setuptools python3-pip
10.python3 -m pip install --user Electrum-4.1.4.tar.gz

All commands go trough and i get a message in terminal saying installation was successful, but there is no electrum folder in local/bin 
and when i try to uninstall electrum  (sudo pip3 uninstall electrum) to start over, i get message saying that can not uninstall since electrum is not installed.

But when instead of last code

Code:

python3 -m pip install --user Electrum-4.1.4.tar.gz

i use this code

Code:

sudo pip3 install Electrum-4.1.4.tar.gz

it works, it creates electrum folder in local/bin and after creating desctop icon as it is described here https://www.addictivetips.com/ubuntu-linux-tips/install-electrum-on-linux/ i am able to launch Electrum.

I want to ask if its ok changing command "python3 -m pip install --user" to command "sudo pip3 install" ?
Can i continue using Electrum installed the way i did, dont i compromise security or privacy?

Im on Linux Mint 20.1 Cinnamon, i want to setup Electrum to run over EPS, now i have to edit config file to add following as it was described here https://curiosityoverflow.xyz/posts/bitcoin-electrum-wallet/#tor-configuration

Code:

{ "auto_connect": false,
"oneserver": true,
"confirmed_only": true,
"server": localhost:50002:s
"skipmerklecheck": true, <-- this is important if your node is pruned
"use_rbf": false }

I also added this in command line of my desktop icon --oneserver --server localhost:50002:s
Now when i edit config file, i save it then close, i start Electrum and all my changes in config file get lost.
How can edit it and save permanently?

Hello

I have installed Bitcoin Core on Linux Mint 20.1 Ulyssa flowing instructions described in bitcoin.org, then i created desktop icon pointing to bitcoin-qt file from bin.
Bitcoin-qt opens up but the the size of it is very large, cant see bottom portion and it doesn't let me to resize it to fit in the screen, i have no such a problem with any other apps on my system. My display setting seems to be setup correctly, i have 1080p monitor attached, but even on my laptop`s screen withoud second monitor i still have the same problem.
I spent many hours trying to find solution but no luck, there are several articles pointing to some QT version issue but non of them have step by step instruction how to fix the problem, i am very new to Linux. I tried to check my Qt version

Code:

sudo qmake --version

  but i get nothing:

Code:

qmake: could not exec '/usr/lib/qt5/bin/qmake': No such file or directory

I found workaround, opened PDF reader, under "about" it shows: Qt: 5.9.5. It looks like this is a up to date Qt version, so I dont know what to do.
Any idea how to fix the issue?

Bitcoin Core gives me an option to use custom address as my change address.
The question is: can i provide my electrum address as a change address in Core? For example i have 4 btc on my Core wallet, i want to send 3 btc to someone, but the remaining 1 btc i dont want back to my Core wallet but i want to transfer it to my electrum, so if i use my electrum address as a change address in Core will it go to my electrum?

Another example: I have 5 btc in Core wallet, i want to send 3btc to Alice and 2 btc to Bob, to make it all in one transaction can i send 3btc to Alice and use Bob`s address as a change address, thus Alice will get 3btc and the remaining change of 2btc will go to Bob.

Hi

When restoring Electrum wallet using option "Use a hardware device" it doesn't restore my wallet unless i put the exact wallet name.
So i have to go new/restore then type exact name of the wallet which i want to restore, then it recovers the wallet.

I did not know that wallet name is important, do i do something wrong? or it is the way it works with Electrum, and i have to not only write down my seed but also a wallet names?

[1st Question]

1st Question
In this article https://curiosityoverflow.xyz/posts/bitcoin-electrum-wallet/ i found out that Bitcoin full node IDB should be done after changing bitcoin-core configuration to run over Tor.

Does it really matter, do i ruin privacy if i download full node without Tor? If its really matters, will it work if i uninstall then do reinstall and setup bitcoin core to run over Tor and download prune node instead of full node, since for EPS prune works as well ( my goal is to set up Core to run over Tor and use Electrum with EPS in order to use Trezor) ?

2nd Question. In the same article it says :

Bitcoin Core will still query for peer addresses via DNS lookup # if low on addresses these 2 options disable this functionality.
dns=0
dnsseed=0
Since we have dns=0 and dnsseed=0, we have to start with some nodes that we can sync from (you can use your own nodes that you can find online.

Can you please give your opinion on this too? Is this step necessary for privacy, if yes can you please tell any secure source where i can find those nodes? The article gives several nodes but i rather use nodes found from some legitimate source.

[I run Bitcoin Full Node trough Tor + Electrum with EPS + Trezor]

Hi !
I run Bitcoin Full Node trough Tor + Electrum with EPS + Trezor
While setting up Bitcoin core config file i have set  walletbroadcast= to 0  as it says in this tutorial https://github.com/chris-belcher/electrum-personal-server/blob/master/README.md

"run tor on the same machine as Electrum Personal Server. Then by default transactions will be broadcast through tor. If running tor, also set walletbroadcast=0 in your bitcoin.conf. This prevents the node from rebroadcasting transactions without tor."

All works well, i receive transactions, but when i want to send a transaction from my Bitcoin core wallet (not electrum) my transaction doesn't go trough, i get a message " unconfirmed, not in memory pool".
I found out that if  i change walletbroadcast to 1 my transactions will go trough. I did so, transaction went thought, and even bitcoin core was still connected to only onion nodes.
In forums i was suggested to use these two methods described below, but im very new to this and dont know exactly how to do it, especially #2 method is very confusing to me.
#1 use the RPC functionality to broadcast the transaction with command: sendrawtransaction
#2 use a script like this: https://github.com/laanwj/bitcoin-submittx which seems to have been purposely designed for working with "walletbroadcast=0" configs.
Can someone please give me a step by step instruction on how to broadcast transactions trough those methods above when walletbroadcast= is set to 0, or what is the best practice in this case, maybe its just easier to change walletbroadcast= to 1 every time i want to send transaction, then to change back to 0? since changing it to 1 i still somehow connect to onion nodes.

Hi ! I use Bitcoin full node running trough Tor + Electrum with EPS
While setting up Bitcoin core config file i have set  walletbroadcast= to 0  as it says in this tutorial https://github.com/chris-belcher/electrum-personal-server/blob/master/README.md

"run tor on the same machine as Electrum Personal Server. Then by default transactions will be broadcast through tor. If running tor, also set walletbroadcast=0 in your bitcoin.conf. This prevents the node from rebroadcasting transactions without tor."

All works well, i receive transactions, but when i want to send a transaction from my Bitcoin core wallet ( not electrum) my transaction doesn't go trough, i get a message " unconfirmed, not in memory pool".
I googled and found out that if i set walletbroadcast= to 1 my transactions will go trough. I did so, transaction went thought, and even bitcoin core was still connected to only onion nodes.
My Questions are:
1. If even with walletbroadcast=1 i manage to connect to onion nodes, then what was the point of setting it to walletbroadcast=0 in the first place?
2. Do i compromise privacy when walletbroadcast is set to 0?
3. Is there a way sending transaction from Bitcoin core wallet with walletbroadcast=0 or i need to change it back and forth every time i want to send a transaction from bitcoin wallet.
Can someone please help me to understand how all this works?
