A step by step guide on how to buy & store the Combicoin/Triaconta (TRIA) cryptocurrency

What is Combicoin/Triaconta?

CombiCoin is a cryptocurrency that is 100% asset backed by the top 30 of all cryptocurrencies.

Important note

This guide is not, and should not be regarded as 'investment advice' or as a 'recommendation' regarding a course of action.

Jan 15th 2018: The cryptocurrency exchange used in this guide, Etherdelta, is currently experiencing technical issues. We advise you not to use it at this time. This guide will be updated when the situation changes.
How to buy Combicoin/Triaconta
Important: The links in this guide are correct as to the best of our knowledge. It is your own responsibility to double check that clicked links look correct in your browser bar, and that any wallet you install on your computer is from a legitimate source.

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

There are three parts to this guide (click to skip to them): Setting up a Combicoin/Triaconta wallet, buying Ethereum and then exchanging Ethereum for Combicoin/Triaconta.


For this guide we'll be using the easiest & most convenient wallet option for storing your Combicoin/Triaconta coins- provided by MyEtherWallet (which can store any coin on the Ethereum blockchain, including Combicoin/Triaconta).

Go to and enter a password that would be hard to guess (but which you won't forget!).

Note: if you forget this password you might lose access to your coins.

Press 'Create New Wallet'.

Creating a wallet at

Click 'Download Keystore File'. Be sure to read and understand the warnings.

It's very important that you back this file up somewhere safe (think multiple external hard drives and/or USB drives that you put somewhere safe).

Once you've done that, click 'I understand. Continue.'

Saving your keystore file

Now you will be given a powerful unencrypted private key to your wallet.

Note: Never give your private key to anyone. If you do, they can open your wallet and take your coins.

Consider printing out your private key and storing it somewhere safe- then deleting all references to it from your computer. Why? Because sometime in the future you might get a virus, or malware, or visit a website with an advert that has malicious code.

These things will target a private key, as it's an easy way to open your wallet and steal your coins.

So why print out your private key at all, if it's so insecure? Because it's your last resort. If you lose your keystore file (e.g. your computer gets wiped or damaged), or if you forget your password, with your unencrypted private key you can still access your account as a last resort.

There is also an option to print a paper wallet (which displays everything you'd need to access your wallet).

If you choose to print this, treat it just like the Keystore file you just downloaded- keep it hidden and keep it safe.

Next, click 'Save your address'.

Saving your private key

Important Note: We all hear of computers and phones being hacked. Websites running illicit code to steal passwords. Phishers tricking people into clicking links that steal information from their computers.

Another line of defence to keep our coins from being siphoned out of our wallets is essential.

And that's a hardware wallet.

Hardware wallets plug into your computer like a USB stick, and they have one job- to be a firewall between your Combicoin/Triaconta and the outside world.

To do this, they encrypt the private keys to your cryptocurrency wallets so that no-one- not even you- can know them. That way only someone with physical access to your hardware wallet- and who also knows its password- has a chance to access and move your coins.

Which hardware wallets support Combicoin/Triaconta?

Hardware wallets made by Ledger and Trezor support the storage and sending of Combicoin/Triaconta.

Where do I get a hardware wallet?

Our recommendation is to either get a Ledger Nano S from their official website or Amazon, or a Trezor from their official site or Amazon.

The Nano S makes it easy to manage your coins- it's compact and discreet, and wallet management is achieved through a small LCD screen and two buttons.

Ledger Nano S

The Trezor is just as easy to use, small and also featuring two buttons, with a lot of information packed into its small LCD screen.


Here's the Ledger setup guide, and the Trezor user manual.


Now we're going to open your new wallet.

Select the 'Keystore File' option, then upload the keystore file you saved in step 2, then enter your password.

Once you're done, scroll down the page to see your opened wallet.

Unlocking your wallet

You will see a long string of letters and numbers labelled 'Your Address'.

This is your personal wallet address, and it's where we're going to be sending your Combicoin/Triaconta coins.

Copy this address and keep it somewhere safe as we're going to need it soon.

Finding your wallet address

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

Choose which Ethereum exchange you'd like to use (by clicking on the logo), and the guide will continue:

Choose your exchange
  • Operates in 32 countries.
  • Accepts debit & credit cards and bank transfers.
  • Can have low buy limits at first, increases with use.
  • ID verification required.
  • Worldwide coverage, 99% of countries.
  • Accepts debit/credit cards and bank transfers.
  • High initial buy limits compared to other exchanges.
  • ID verification required.
There are also some other exchanges (but without step by step guides) 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.

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.

Note: If you have problems verifiying your ID using your computer, try downloading the Coinbase app (on Iphone or Android), signing into your Coinbase account and verifying your ID using your phone camera.

Signing up to Coinbase

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

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

Select 'Ethereum', 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 Combicoin/Triaconta, encouraging its popularity and value to grow.

Here's some share buttons to make it easy:


Before we do any trading, we're going to adjust the 'gas' amount that our Etherdelta transactions consume. This will help keep things moving swiftly, as Etherdelta's default settings can mean long waits for coins to move.

On the top menu click the furthest right button, then select 'gas price'.

In the popup that opens, you want to type a minimum of '30', and then click 'Set gas price'.

Note: If you don't set a high enough gas price your transactions can be very slow, or even fail, so we encourage you to visit this site and pay attention to what the 'Recommended gas price' is at this moment. We suggest setting your Etherdelta gas price to be the same as the 'Gas Price (gwei)' number suggested for 'Standard (<5m)'.

Here's more information on how gas works.

Etherdelta exchange

Once the Ethereum is in your account it will show under 'BALANCE'.

Now we have to move that Ethereum so that it's available to trade. Beneath 'ETH' In the box marked 'Amount' enter how much Ethereum you're ready to trade for Combicoin/Triaconta.

Note: Do not enter the whole amount of Ethereum. You need to leave a little in this wallet to cover gas fees. For example, if you have 10 Ethereum to trade, enter 9.95 in this box.

Once you're happy with the amount, press 'Deposit'.

Etherdelta exchange

A pop-up will appear to let you know you're moving the coins. If you wish, you can click the link it gives you and watch the transaction take place on the Ethereum blockchain.

Etherdelta exchange

Once the Ethereum has moved to the 'Etherdelta' column in your balance you're ready to trade.

Etherdelta exchange

Look at the 'Order Book'. This is telling you the current buy and sell orders for TRIA. The red orders are users wanting to sell TRIA, the green orders are users wanting to buy TRIA.

Let's look at each column by itself:

TRIA/ETH - this is the ratio of one coin to the other, for example, 0.01 in this column would mean 0.01 Ethereum will buy you 1 TRIA.

TRIA - this is the number of TRIA that the user wants to buy or sell.

ETH - this is the amount of Ethereum that the transaction will cost.

Etherdelta exchange

Buying option one

The first (and easiest) way to buy TRIA is to simply click a (red) sell order, and in the pop-up that appears press 'Buy'.

Note: There are sellers who purposefully list coins at a bad exchange rate in an attempt to trick users into paying too much. Be very careful to check that the sell order is offering a fair price. Use this calculator to be sure you're getting a reasonable exchange rate of Combicoin/Triaconta to your Ether.

You can edit the amount of TRIA you're buying in the 'Amount to buy (TRIA)' box if you don't want to buy the full amount of the order.

If the exchange is successful a pop-up will appear with a link to the transaction on the blockchain.

Etherdelta exchange

Buying option two

The second option (and one we do not recommend for first time users of Etherdelta) is to buy TRIA by using the 'New Order' option.

In the 'TRIA' box type how many TRIA you'd like.

In the 'TRIA/ETH' box type the ratio you'd like to buy at. Be very careful- Etherdelta has become notorious for users being confused by what ratio to use and exchanging their Ethereum at a terrible rate.

For a good idea of what ratio to use, look at the top buy order for what the going rate is- in the example image it is 0.011. This translates as 0.011 Ethereum coin buying 1 TRIA coin.

The next box, ETH, will automatically fill with the amount of Ethereum this transaction is going to cost. If this looks correct, go ahead and press Buy. The order will go onto the exchange. It will either be filled by a seller, or will eventually expire, which means your Ethereum will be returned to your trading balance unspent.

Etherdelta exchange

If you used buying option one your TRIA will soon appear in your Etherdelta wallet.

If you used buying option two, the TRIA won't appear until your order is filled.

Either way, once the TRIA is in your wallet, you're going to want to move it to your Myetherwallet address.

In the 'Balance' box press 'Withdraw', and in the box under TRIA, type the amount of TRIA in the Etherdelta column.

Press 'Withdraw'.

A pop-up will give you the transaction address if you wish to view it on the Ethereum blockchain.

Your TRIA will take a few minutes to move from the 'Etherdelta' column to the 'Wallet' column. When it has, this means the TRIA are currently residing in the wallet we created in step .

Etherdelta exchange

But we don't want it there, we want it in the secure and backed up wallet we created in step 5. So, in the Balance box, click 'Transfer'.

In the box under TRIA write the amount of TRIA in your wallet.

Replace the current wallet address with your Myetherwallet wallet address- the one we copied down in step 5.

Note: You CANNOT store Ethereum tokens, such as Combicoin/Triaconta, on Coinbase. If you send your Combicoin/Triaconta to Coinbase you will lose them.

Click 'Transfer'.

Note: We suggest you do a test transaction first using a small amount of TRIA.

A pop up will appear with the transaction reference on the blockchain.

Etherdelta exchange

Go back to MyEtherWallet.

You should now see the Combicoin/Triaconta (abbreviated to TRIA) in your wallet under 'Token Balances'.

Not all newer tokens automatically show in your token balance list. If this is the case with your Combicoin/Triaconta, follow this tutorial to have them show up.
MyEtherWallet token balance

One note of importance is that the example wallet in this guide has no Eth in it. Why is that important?

Combicoin/Triaconta coins exist as a token on the Ethereum network. To move Combicoin/Triaconta coins across that network costs 'gas', which are in the form of Ether coins. If in the future you want to move your Combicoin/Triaconta coins to another address, you're going to need some of those Ether coins to power the transaction.

You already know how to buy Ether, but you can use this guide if you're still unsure how to move them to your personal wallet.


What about when you're ready to sell your Combicoin/Triaconta?

You simply reverse the order of tasks you performed in this guide.

For example, you send your Combicoin/Triaconta to Etherdelta, exchange it for Ethereum, send that Ethereum to Coinbase Local Bitcoins and sell it for your preferred currency.
