Much more than bitcoin replicas

Altcoins began life as little more than bitcoin copies attempting to mimic bitcoin’s successful run, but they quickly became much more than their name suggests. At the time of writing (February 2018), there are more than 1,500 altcoins available for use. While many are still struggling to break the mould set by bitcoin, some are doing truly amazing things with the technology.

From rethinking the entire concept of what the blockchain could and should be used for (Ethereum) to building a purely anonymous and secure network for peer-to-peer transactions (Monero), more and more altcoins are addressing the shortcomings of bitcoin every day, innovating on its basic driving technology to become market leaders themselves.

The blockchain

The blockchain is the underlying technology that drives all altcoins and the best way to visualise the blockchain is to think of it as a digital ledger. Let’s imagine a paper ledger into which cash transactions are entered. Mary would like to pay Jason $100. She meets Jason at a cafe along with Terry, the person in charge of maintaining the ledger. Mary gives the $100 bill to Jason, Jason puts it in his pocket, and Terry notes down the transaction: Mary to Jason $100.

The blockchain is like a collection of pages on that ledger. Each “page” is called a block and contains multiple transactions. Whenever a block is filled up and a new transaction comes in, that transaction creates a new block with a link to the previous block. This new block is then appended to the blockchain. Once a transaction is written into the block, it becomes immutable: it cannot be edited or deleted.

The best part of the blockchain is that all the users on the blockchain receive a copy of this ledger. They can update their own ledger, and then pass it on. This way, all users can confirm that Mary gave $100 to Jason, and Jason can’t say he didn’t receive the money.

Initial coin offering (ICO)

Similar, even in name, to an initial public offering (IPO) in which a private company’s stock first becomes public, an ICO happens when a cryptocurrency startup wants to raise funding in order to further the development of their coin. The startup releases some of their coins (often referred to as “tokens”) to traders, who purchase these tokens in the hope that the project succeeds and those coins gain value. If the predefined minimum funding is not reached, the money is sometimes returned to the traders.

ICOs, unlike IPOs, are unregulated and so great care should be taken before participating in one to make sure that it is not, in fact, a scam.

The future of altcoins

Altcoins are the new kid on the block and they are as unpredictable as they are exciting. With the biggest altcoins vying to take the top spot from bitcoin, they are all attempting to carve their own niches, with goals nothing short of re-imagining the way we do business, how we send and receive money, and how we transfer assets like properties and cars.

      Hi Jim,

      Thanks for getting in touch with finder.

      Unfortunately, we currently don’t have detailed information of ICO issuers. However, you can simply search for upcoming ICOs and you’ll find hundreds of them. Just remember that most of them probably won’t go too far. Look for the ones that offer more use, more practicality and show every sign of being set for success.

      In many cases, you’ll also notice that they only accept certain currencies. The most commonly accepted are Ethereum and bitcoin, so you might need to buy one of those first and then trade it for the ICO coin.

      If you need to know more information about ICOs, here’s a helpful guide.

      I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.

      Have a wonderful day!

    What do I need to provide to a tax agent for tax purposes when I buy or sell cryptocurrency. I found the link on this site once but it’s now lost.

      Hi Reuben,

      Thanks for getting in touch with finder.

      According to ATO, when transacting with cryptocurrencies, you need to take note of the following transaction:

      the date of the transactions
      the amount in Australian dollars (which can be taken from a reputable online exchange)
      what the transaction was for
      who the other party was (even if it’s just their bitcoin address).

      I’m not sure what link you are referring to but you might find the following pages helpful:

      Moreover, you might also want to read how the Australian Government treats Bitcoin and other cryptocurrencies. Here’s a link.

      I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.

      Have a wonderful day!
