[PSA] Small guide to help you set up bitcoin trades

Since nearly every day someone asks how bitcoin trading works here is a small guide to get you to set-up a wallet, sending and recieving bitcoin guide.
What is bitcoin (quoted from the wiki):
Bitcoin is a cryptocurrency and a payment system invented by an unidentified programmer, or group of programmers, under the name of Satoshi Nakamoto. Bitcoin was introduced on 31 October 2008 to a cryptography mailing list, and released as open-source software in 2009.The system is peer-to-peer and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in a public distributed ledger called the blockchain, which uses bitcoin as its unit of account [1].
From personal experience I have found out not to read too much about it. When I decided to switch from paypal to bitcoin I tried reading up everything I could find about mining/nodes/hashes etc but it only made things more confusing than it actually is. The thing to remember is that bitcoin is a currency and like any other currency, the value can be represented by another currency (or goods). So 1 BTC today might be worth 800+$ and tommorow 8 or even 8000$ (highly unlikely but still you get the idea).
In terms of skins, imagine everyone on the sub really wanted a glock fade. Naturally the price of the glock fades would rise since more and more people are willing to buy them there will always be someone who offers more than the next guy untill some cap is reached. Vice versa devalueing the glock fade can also happen. If Valve releases a new sick glock the value of the fades will decline since everyone will sell theirs and stock up on the new glocks.
Okay now what?
Now we need a place to store our bitcoins we will recieve/spend in the future. The place you store it isn't a bank account but a so called wallet. There are two types of wallets that I know, hardware and software wallets. Hardware wallets are physical wallets (like usb-dongles or cards) since I have no experience with them I won't try to recommend one. There are 2 types of software wallets (again to my knowledge maybe there are more?) so called online-and offline wallets. Since I have a minimum experience with offline wallets (I only know downloading the blockchain takes ages) I also won't discuss that in this guide.
Online wallets.
Online wallets are wallets that are stored by a company. The great advantages are that they don't require you to download the entire blockchain (last I've read it's somewhere ~100GB in size [2]) and is super user friendly. Some websites that offer the online wallet services are: and
Setting up your wallet.
Most of these website work in a similar fashion when you want to set up your wallet. As an example I will show you how to set up your wallet using (no I`m not sponsored by them, would be dope af though :) ). When you first open up the webpage you will see:
To create a wallet click on the tab which says 'Wallet' (indicated by a red arrow in the screenshot above) and you will be directed to a new page:
After clicking on 'Create A Free Bitcoin Wallet' (indicated by a red arrow in the screenshot above) you will be redirected to a page where you need to fill in some information incase you lose your password. It is adviced to use a strong password since it is a place where you store your bitcoin/money. Protip: don't store your password on your computer, write it on a piece of paper and store it somewhere where you keep your other important stuff. 'But Ozzy what happens if I download a keylogger on accident?' No worries we will enable 2FA in a moment.
By now you should have recieved an e-mail from blockchain providing you with your wallet-ID. This ia string of numbers and letters. As a safety measure (if you lose your e-mail PW or w/e) write your wallet-ID also on a piece of paper and store it somewhere safe.
After you fill in your wallet-id (happens automatically) and your password you will see the following message (indicated by a red arrow)
This is a safety measure of blockchain where they provide you with an e-mail with an authorisation link if you don't click this link on your e-mail you can't acces your wallet. After you click the authorisation link you can close the page where you clicked on the link and return back to your original log in page. There you will see that you are authorised to acces the wallet.
After you have logged in you will be greeted with the main page of your wallet, head on over to the security center to enable 2FA straight away. Your fresh wallet won't have any transactions obviously :)
At the security center you can enable stuff like, e-mail verification, phone verification, 2FA etc. Phone verification let's you download the blockchain app to your phone and link it with your wallet so you can 'spend BTC on the go'. 2FA is simply put an extra verification app you download (like google authenticator) which adds an extra layer of security on your wallet.
Acquiring bitcoin:
There are a number of ways on which you can acquire bitcoin. Selling stuff for bitcoin, buying it from people (ie or buying from companies (ie I only have experience with Dutch companies since Dutch law takes internet scamming very seriously I have never bothered with buying bitcoins from individuals.
Sending bitcoin:
If you want to send bitcoins for goods/services there are 2 things to know. First the wallet address of the person you send it to (I`ll be using a friend's address) and how much bitcoin you need to send. To look up the current conversion rate (BTC/USD) you can use external sites like or you can use blockchain's handy converter built into the send page. Click and paste the wallet address to which you want to send bitcoin to (be sure to double/triple check it) and the ammount of bitcoin or USD you want to send
After you have pressed 'Next step' you will see another confirmation page where you see a summary of how much btc you send to which address and a transaction fee (used for confirmations)
After your confirmation your transaction will show up on the 'Transactions' tab. When you press the dropdown arrow you will see the ammount of confirmations your transaction has. Since I just sent my bitcoin the transaction isn't confirmed by the blockchain yet. Without checking the confirmations you can have a false sense of security (bitcoin transactions can't be charged backed right?) that the bitcoins are in your wallet. This type of scam is called 'double spending' to read on the dangers of this read the post of u/JackBauerCSGO here So wait for a minimum of 1 confirmation before trusting the fact that you indeed have the bitcoins.
Recieving bitcoin:
Head over to your 'HOME' page again and click 'Recieve' to find out what your bitcoin wallet address is.
You can see that mine is 1BJQKMCe6zcAFut5fwc4GM49uNf7aH8cQf (note: this is NOT the same as your wallet ID!). This address unique and connected to my wallet only (basically is my wallet). If I were to recieve bitcoin from someone I would link him those letters/numbers to let him know to which address he needs to send the bitcoin. On the right you can see the QR-code of my wallet, if I were to recieve bitcoin from someone who has a bitcoin app I could simply send him that QR-code to let the app know where to send the bitcoin to instead of the numbers/letters.
That is bascially all you need to know to get in to bitcoin trading.
Your next step in to actuall trading is finding someone who sells skins/keys for bitcoin agreeing on a BTC price and setting up the trade (small note: please don't forget to double check their steamrep/cashrep.)
Note: I am in no way shape or form a bitcoin expert, just a globaloffensivetrade user who has dealt with bitcoin for the past year or two. If you have questions feel free to post them and I`ll do my best to answer it.

A helpful discussion about wallet security (esp. Electrum)

I was recently contacted via private message by a redditor who read a comment of mine about wallet storage (I assume this comment). I think there was quite a bit of useful information in it for other bitcoin beginners, so I am reposting it here in full (with permission). The redditor in question wanted to remain anonymous though.
I hope this is of use to some of you here!

I saw your post regarding your wallet storage and had a few noob questions if you don't mind.
My plan is similar to yours but I was unsure whether to use armory or electrum (electrum's seed creation scares me a bit).
You mentioned you have a bootable LINUX (ubuntu?) USB stick that you keep your wallet you only boot this onto an always offline computer?
Do you use something like Truecrypt to further protect your wallet.dats?
Thanks for your time!

My plan is similar to yours but I was unsure whether to use armory or electrum (electrum's seed creation scares me a bit).
For me it is the other way around. Armory (and bitcoin-qt) scare me. Armory is just a wallet. It still needs bitcoin-qt running in the background. For me the problem is two-fold:
1) Size
bitcoin-qt (and armory) need to download the entire blockchain. That 13+ GB that takes hours to download and days to verify. And if you ever lose it, you need to do it again.
2) Random keys
armory and bitcoin-qt generate random private keys. You get 100. If you use a few (you use them when you send coins for example) then new ones are created. So, if you create an armory wallet and make a backup, that backup will have 100 keys. Then, if you make 33(!) transactions, your 100 keys are used up and you will have 100 different random keys. If someone then steals your computer (or your house burns down) then you cannot use your backup anymore. It only has the 100 old keys and none of the new keys. So you have lost all your bitcoins.
Why 33 transactions and not 100? Because of change addresses. If you have 10 BTC and send me 2 BTC then most wallets will create 2 transactions. 2 BTC from your old addres to me, and 8 BTC from your old address to a new (random) address. This process costs 3 private keys. 2 keys for the transactions and 1 key to create a new address.
This means that after every few dozen transactions you need to refresh your backup so it has the newer keys. For me that is impractical. It means that I need to keep my backup close by because I often need it.
Electrum does not have this problem. The seed solves this. Private keys are not random but are created from the seed. If you have the seed then you have, by definition, all the private keys you will ever need. Your backup can never be out-of-date. This is easy for me. I save the seed in a file, encrypt it, put it on an USB stick and give copies to a few family members who have safes in their homes.
If my computer is ever stolen, or my house burns down, I can go to a family member, decrypt the seed file and use the seed to restore my electrum wallet. Even if that USB stick is 10 years old.
You mentioned you have a bootable LINUX (ubuntu?) USB stick that you keep your wallet you only boot this onto an always offline computer?
It depends on how secure you want to be. For maximum security, keep the computer always offline. But if you want to spend the bitcoins from your wallet, you will need to be online.
I use the USB stick for my savings account. It only receives coins and I do not send. So I do not need to boot up my USB stick. I have created a second wallet on that I use for day-to-day transactions. All BTC I receive goes to my blockchain account. Then I transfer a part of that to my savings account and only keep a bit of change that I need in the blockchain account.
Do you use something like Truecrypt to further protect your wallet.dats?
No. Electrum does not have a wallet.dat. It has the seed. I simply copy the seed to a TXT file and encrypt it using GPG and symmetric encryption. Example:
gpg --armor --symmetric --cipher-algo AES256 seed.txt 
Make sure you use a password that is strong and that you cannot forget! If you need to write the password down on paper and your house burns down, then you cannot decrypt the seed anymore!
From: Anonymous Redditor
Forgive the naivety here: Correct me if I'm wrong - The safest way to generate your wallet seed is on an offline computer correct? So, theoretically, generate the seed on an offline-only computer, copy to txt...encrypt. back up on multiple USB's. Then on your online computer, load electrum and import Seed?
Thanks so much for the thorough explanation! I'm a potato when it comes to reddit's bitcoin tip bot. Send me an address - would like to send some internet magic money your way.

The safest way to generate your wallet seed is on an offline computer correct? So, theoretically, generate the seed on an offline-only computer, copy to txt...encrypt. back up on multiple USB's. Then on your online computer, load electrum and import Seed?
Not quite. The risk with an online computer is malware and people breaking in. If you generate the seed on an offline computer and then move it to an online computer, you don't really take that risk away. You still have your wallet on an online computer which you use for day-to-day work and which is exposed to hackers and malware.
I suggest you make two wallets. One wallet is your "savings" wallet. You can use the USB stick Linux for this. Generate the wallet offline, backup and encrypt the seed onto multiple USB sticks and note down the bitcoin address somewhere so you can transfer funds to it. The only time you should use the USB stick to go online is when you want to transfer funds out of your savings wallet.
The, on your normal computer (or your smartphone if you prefer), create a second wallet using a different password. This is the wallet you keep only a little money in for your day-to-day transactions. Note down the seen, encrypt (with a different password than you used to encrypt the seed from your savings wallet) and add it to the USB keys. You can use Electrun for this second wallet as well, but you can also use something different. I use a wallet for my day-to-day expenses.
Whenever you have a larger amount of bitcoins in your day-to-day wallet, transfer some to the wallet on the USB stick. You don't need to boot up the USB stick for this. You only need the address you wrote down.
When you want to spend a large amount of money, boot up from the USB stick and transfer coins from your savings wallet to your day-to-day wallet. Reboot into your normal computer and use the day-to-day wallet to pay for what you wanted to buy.
The core of the issue is simple: Don't store a lot of money in a wallet on a computer that you use a lot. Computers that are used a lot get attacked a lot. Simple :-)

That is very kind! My address is: 1PAXiscvKoGRJ5XxMZvri3CMNeKYYb8wMQ
From: Anonymous Redditor
You are awesome:) Thank you again for the insight! Sent some your way.
From: SanderMarechal*
Your welcome. And thanks for the coin!
From: Anonymous Redditor
Last question(s) (I promise)...
Would a netbook like this be appropriate to 1)dban 2) boot up via USB ubuntu and 3) create the electrum seed?
This would of course never go online, be backed up and encrypted, etc.
Thanks again.
From: SanderMarechal
I don't know. You would be better off asking this on for example. I don't know if that computer's hardware is compatible with Ubuntu. Speed-wise the bottleneck will be the USB stick and not the CPU or memory. USB sticks are much slower than hard drives.
Note that you don't have to buy a computer for this. You can use the computer you already have and still run Ubuntu off an USB stick for your Electrum wallet.
What I said in my previous post about not using your day-to-day computer for your wallet, with that I mean the operating system and software. Not the hardware. Unless you're afraid someone put a hardware keylogger inside your computer :-)
From: Anonymous Redditor
My tin foil hat is in full effect:) Thanks again for your time and patience.
From: SanderMarechal
Your welcome. Have fun with bitcoin!
Oh, I have a question for you now. Would you mind if I repost our entire private conversation here to /BitcoinBeginners? I think other redditors there would also be interested. And if I can repost it, do you want your username in there or should I replace it with "Anonymous Redditor" or something?
From: Anonymous Redditor
You can certainly repost it! And yes, if you wouldn't mind removing the username I would very much appreciate it.
Thanks for asking btw!
Anyway, I hope this is useful for some people out here.
