If you are fine with using linux do the following:
1. Download a linux distro (you can go with Ubuntu)
2. Download Electrum or any wallet of your liking
3. Buy a USB stick (at least 2GB, but 4 and up is suggested)
4. Put the linux ISO on the USB stick and add persistant
5. Turn your router off and disable network inside that linux OS
6. Install the wallet on your linux
7. Now you have a cold storage that you can spend from

I can make a detailed tutorial with screenshots if there is enough interest in it but it will take time

hehe! Thanks for taking an interest in my project but as the title suggests it is a "Watch-Only" wallet and it is used to keep tabs on your bitcoin addresses, balances and price.

What OP was looking for was a real bitcoin wallet, i assume with functionality to create addresses with private keys, sending (signing) transactions from, and all that.

Version 2.0.0 is complete, and will be merged as soon as I find some time to test it (It has been a busy month).

https://github.com/Coding-Enthusiast/Watch-Only-Bitcoin-Wallet/tree/MVVM

Included in this version:

• Code is following the MVVM pattern!
• Every bitcoin address is checked to make sure it is a valid base58 address
• GUI changed to GridView to make Add/Edit/Remove Function easier
• MainWindow now has hotkeys for Saving (Ctrl+S), Opening Settings (F2), Opening Help (F1)
• Added a new option in SettingsWindow to get bitcoin price from 2 different exchanges (bitfinex and btc-e)

As always feel free to leave any suggestion, feedback, request,... here or on GitHub.

When you first install Electrum and run it for the first time it checks the wallet default location which is C:\Users\UserName\AppData\Roaming\Electrum\wallets on windows and if it can find a wallet then starts using it. From what you said I think Electrum has found a wallet there, probably from your last install and started using it.

If that wallet is password protected, the only way you can access your funds is knowing the password or remembering the seed you had the first time you installed that wallet.

There is also an option to brute force the password and try cracking it but that requires you to know at least something about the password.
For example know that it is 10 letters with a name "Termo" and number "462" in it. If you know nothing about the password, then nothing can be done.

If by "test" you mean using the wallet, e.g installing 2.6.3, transacting bitcoin, updating to newer versions, continue using, report bugs on bitcointalk/reddit/GitHub; then yes a lot of people are doing it.

If by "test" you mean check the code and see if there is any bug in it then there are 6 developers who have more than 50 commits, and a total of 136 contributors to the open source code
ref: https://github.com/spesmilo/electrum/graphs/contributors
and I am sure there has been others who checked the code over the years and would have or already have reported bugs.


GitHub 101

• Go To https://github.com/spesmilo/electrum and search for make_seed or any other things you want to see changed.
• You will end up here: https://github.com/spesmilo/electrum/blob/master/lib/mnemonic.py#L162
• Now look what has changed if you were following Electrum development.
• If not click on history and start reading the changes.
  
• To see which versions the change affects see the Tags
  * I have no python knowledge so you may want to check the links yourself!

You could have easily gone on GitHub and read the Release-Notes:
https://github.com/spesmilo/electrum/blob/master/RELEASE-NOTES#L1-L115

As you can see there were no issues with seeds generated on 2.6.3

There were some bugs introduced with for example 2.7.5 the utf8 bug for password extended seeds (a new feature in 2.7 versions) which are removed now.

@doof Thanks a lot for your feedback.


I am still new to C♯ and definitely to MVVM and the reason why I did that was because I got an error in my view (MainWindow) xaml file which was unable to resolved the dependency! This and some other bugs/problems are the reason why I have not yet merged that branch.

But I like the follow up about open/closed principle after reading more about it.
So should it be like this:
In ViewModel:
In Services:

I have tried to make it as simple as possible so it is easily understandable by anyone even with no bitcoin knowledge. So I believe what you say is not completely right here.

And unless you have any suggestions or problem with something in particular, your comment here is not constructive.

For that I am going to need access to price history of each hour or at least a medium price of days. I can't find this on Bitfinex API nor on Btc-e. Did not check any other place for price history though.

I will think about adding a new column for Balance in USD

- I am not using web wallets like Coinbase or Xapo and those are the only wallets that can have such thing as withdrawal threshold. You have to read their ToS on the respective websites.
- Besides don't forget that the suggestion is only for cases that you want to keep "small amount" in these sites so withdrawal threshold should not apply in this case.

- Already made possible from the Settings Window, using bitfinex and btc-e APIs:

- Maybe someday
- This is possible with a WebSocket API which I think Blockchain.info has. So i guess that can be done but for the next version.

Version 2 is getting ready for release:

Major new features:

• Code is following the MVVM pattern now
• The wallet GUI is using the GridView which gives a more excel like view making it easier to add/edit/remove items.
• Input validation is added to prevent user from entering an invalid bitcoin address

I want to work a little bit more on the code so I am still not merging this with the main branch. But you can see the development on the MVVM branch
Feel free to give me any suggestions or requests. 

That is much better.
A couple of additional suggestions:

• Your link is https://github.com/Voladimer13/BTC-E-Trader---Source-Code without the ".git" that is for cloning (downloading the whole repo)
• Read the link i gave you on stackoverflow to do it much easier and faster from inside Visual Studio.
• You need to add a ".gitignore" file to exclude "binaries (.exe)" and that unnecessary ".rar" file which you have. There is no need to make a separate archive file git with make it automatically from the repository when you use that link with ".git" at the end. And if you want to keep a history of releases you can do something like this https://github.com/spesmilo/electrum/releases from your "Releases" tab.

p.s. I am a bit busy these days with multiple project at hand (learning and developing at the same time) but I will make sure to check out the code in detail and contribute if I can.
For now I suggest you should look into .gitignore and what you should and should not include.

First impression:
Is it your own code or did you copy it from somewhere? Why is it checking for new version from sourceforge?

The code is too crowded.
e.g. frmMain.cs file is 2201 lines. Separate the business logic and GUI, Look into using WPF (xaml) instead of winforms and also take a look in MVVM pattern. Reading all this code in one place mixed with GUI is not easy and will cause lots of bugs and makes maintaining and updating code impossible.

Warning: This may or may not be scam!

There are a couple of things wrong here. Which are making this whole thing shady.

• Why a short link for downloading?
• Why torrent?
• Is it the source code?
• You have vouch/bump from two throwaway newbie accounts!
• Why not upload it like a normal person on a normal code sharing site like GitHub so anyone can see, review and report back, and also most importantly contribute.

I liked the screenshot (how the bot looks) but I will never download it unless the source code is uploaded on GitHub so that I can go through the code with ease.

Convenience and Ease of use is in the heart of the last Diamond shape asking about the internet speed and storage space.
The purpose of a flowchart is never to go through all the small details of everything, and I have tried to make mine as simple as possible so that if you don't know anything about bitcoin you can take a look and get a "general idea".


This is how you see it on the forum because of the restrictions of resolution and being in-line. I have also added a width tag to the image so it is smaller in order to prevent crowding all the space in the post.
You should click on it (it is an imgur.com link) and see the image in the real size which is 2000x1365 pixels and I believe it is more than enough for being readable. If not I can upload the original resolution of 9124x6193 pixels!

I did change the colors and the font a little bit though. (check OP)


1) Added.
2) That is not right. bitcoin core or Armory does not provide any addition security that you can't get from other wallet options like an SPV wallet (Electrum or Multibit) or paper wallet.
3) I try to stuff in as much information as I can without crowding the flowchart making it hard to follow.


Can you give me an example with more details?

This may not be so relevant to your questions but there is a Console tab when you open Electrum where you can type in commands such as help() which brings up the list of all commands you can use:


and then you can use each of these inside that Console.

Instead of naming all the wallets, and for brevity I've added the link with its QR (for ease of use) to the top.

I have made a simple and short flowchart to help with choosing a bitcoin wallet.
Tell me what you think about it and how can it be improved.

It is a Microsoft Word Document (.docx format) that I can also share after it is finished and if anyone was interested.

Click on the image to see the large version on imgur if it is hard to read:


History:
Edition 1: https://i.imgur.com/1BXMQB9.jpg
Edition 2: https://i.imgur.com/EOeaBZe.jpg
Edition 3: https://i.imgur.com/CFp3lbJ.jpg

It is in 2.7.0 or 2.7.1 and is similar to this: https://bitcointalk.org/index.php?topic=1637501.0 (also)

Upgrade to latest version should fix this.
