How to buy Siacoin
Important: Be wary of scammers trying to steal your crypto coins - get into the habit of double checking that URL's look correct in your browser address bar when moving / purchasing / selling cryptocurrency.

Notes: Images can be clicked to see a larger version. If you're confused by any terms used, a glossary can be found here.


To start, let's download the official Siacoin wallet, where we'll keep your coins safe on your computer. Once installed, the wallet takes a few hours to synchronise with the Sia network, so best to start now.

If you wish to speed this process up, you can follow the instructions here.

Download Sia wallet

Open the downloaded .zip file and extract the files to a new folder. Rename the folder 'Sia' and place it somewhere on your computer where it won't get accidentally deleted.

Extract Sia

In the folder, double click the file named 'Sia-UI.exe' - a security warning may pop up- click run.

Open Sia

The Sia user interface will now be open. Your firewall may issue a warning- press the button 'allow access' to allow Sia to connect to the internet.

Windows firewall

Now it's time to create a Siacoin wallet. Click the 'wallet' option on the left sidebar. Click 'create a new wallet'.

If you wish, choose the option to use a custom passphrase- which simply means you'll input your own password on the next screen rather than use the one Sia generates for you.

Sia wallet

You will now see your wallet 'seed' and 'password'. If you chose not to input your own password, these will be identical. It is very important to back up these pieces of information somewhere safe and private. They are the key to your wallet. If anyone gets ahold of this information, they can access your wallet too.

Note: the seed and password in this image are for example only. Do not use them yourself.

Once you have the seed and password safely stored, click the button 'I have written these down in a safe place'.

Sia seed and password

Now it's time to test that you have your password written down correctly. Type your password into the prompt and press 'unlock'.

Sia password

Your wallet is now open and ready to receive Siacoin. Notice the 'synchronizing' status bar in the top right corner- leave Sia running until this reaches 100% or the wallet won't register any of the Siacoin's we're about to buy and send to it.

At this point it's good form to backup the wallet files that Sia has created on your hard drive stored at:

(WIN) %UserProfile%\AppData\Roaming\Sia-UI\sia\
(LINUX) ~/.config/Sia-UI/sia/
(Mac) ~/Library/Application Support/Sia-UI/sia/

Copy all the files inside that folder and back them up on a USB stick or external hard drive, and keep that somewhere safe. These wallet files aren't strictly necessary in recovering your Siacoin wallet, but they are another layer of security.

Sia sync

Even though your wallet hasn't finished syncing with the Sia network you can still safely receive coins to it.

Click 'Receive Siacoin'. The wallet will give you an address to send your Siacoin to. Copy this somewhere safe as we're going to need it soon.

Important note: Each time your click the receive button in the Sia wallet it will give you a new address. This is a security feature of Siacoin and nothing to panic about.

Now we'll purchase the popular cryptocurrency Bitcoin, so that we can exchange it for Siacoin (if you already own Bitcoin you can skip ahead).

Choose which exchange you'd like to use to do this, and the guide will continue:

Operates in 32 countries.
Worldwide coverage, 99% of countries.
There are also some other exchanges listed here.

If you use this link to sign up to Coinbase we'll both receive ten dollars of free coins when you spend over $100 (or the equivalent in your currency).


Press the 'sign up' button and fill out your name (make sure this is exactly how it's written on your photo ID), email, password and location.

Just like a US bank, Coinbase is regulated by the US government, and has to follow strict financial rules. So they take verifying your identity very seriously. It's a pain, but it does give Coinbase a reputation for being the most trusted way to convert fiat currency to cryptocurrency.

Signing up to Coinbase

To verify your account you must supply a phone number, upload an image of your photo ID and verify a credit/debit card or bank account before you can buy.

Using a credit/debit card means higher fees but offers instant purchasing. Using a bank transfer is cheaper but slower (taking up to a week to get your coins).

Signing up to Coinbase

Once your payment details are verified, click 'buy/sell' on the top menu.

Select 'Bitcoin', and at the bottom of the page choose how much to spend in your local currency / how many coins you want to buy.

Once you're happy with the amount, click the big 'Buy' button.

While you're waiting, consider sharing this guide with your friends and followers to spread the word about Siacoin, encouraging its popularity and value to grow.

Here's some share buttons to make it easy:


On the Bittrex wallet page, click the 'hide zero balances' tick-box to make it easier to tell when your Bitcoin has arrived.

Once it shows in your 'available balance' we're ready to trade for Siacoin.


Click here to be taken to the Bitcoin / Siacoin exchange section of Bittrex.

This interface is where we will trade your Bitcoin for Siacoin. It looks overwhelming at first, but ignore the charts- all we're doing is a simple exchange from one coin to another.

This means we'll be purchasing Siacoin at the price (per coin) of about $

You can use the Bid or Ask options if you wish to try and time the market to buy at a cheaper price, but that's a little more advanced than we're covering in this guide.

Press the 'Buy Siacoin' button. Then 'confirm' in the pop-up box. Your order is now activated.

Siacoin exchange on Bittrex

Depending on the market, your order may be filled immediately (meaning, your Bitcoin was instantly converted to Siacoin) or your order may be waiting for enough Siacoin to become available at your chosen price to fulfil your purchase request.

To see if your order is still active, or has been partially filled, click the 'orders' button on the top menu of Bittrex. If your order is showing, you may choose to cancel it and attempt to purchase at a different price, or simply let the order sit to see if it's filled.

When your order has been filled- you can proudly say you're the owner of your own Siacoin!

Siacoin exchange on Bittrex

Click wallets, and make sure the tick-box 'hide zero balances' is selected. You should now see your Siacoin in your Bittrex Siacoin wallet.

If you're planning to keep your Siacoin on the exchange you can stop here. But please note that exchanges are targets for hackers, they have been hacked before and had coins stolen.


Click the - (minus) sign beside the Siacoin wallet and it'll bring up a screen for you to input your withdrawal details.

Put the wallet address that you copied from Siacoin (in step 9) into the box labelled 'address'.

In quantity, we would suggest doing a small test transaction of a couple of coins to be sure everything is working correctly. Press 'withdrawal'.

It will take a few minutes for your Siacoin to transfer.

Note: Bittrex may ask you to confirm the withdrawal by clicking an email link or inputting a code from your mobile.

Coins in Sia wallet

Now that you have coins in your wallet you may want to consider staking some of them and selling any unused space on your hard-drive. There's more details about this on the official Sia website.

When it comes time that you want to send your Siacoin to another wallet or exchange, it's as simple as pressing the 'send Siacoin' button in the Sia application, inputting the amount of Siacoin you wish to send and the wallet address you're sending it to.
