Bitcoin: Know the risks before you buy

‘Bitcoin is right now the riskiest investment you can make.’ Here are the risks you should consider before you buy.

As bitcoin hit a record high of $19,000 a coin in December, the cofounder of the website warned that bitcoin was “the riskiest investment you can make”. 

Here are some of the things you should consider before you jump on board.

What is bitcoin? 

  • A cryptocurrency is a digital form of money that you can use to pay for some transactions online. Bitcoin is the most popular of the so-called “cryptocurrencies”.

  • As with “real” currencies (like the US dollar), you can own one, 10, or millions of bitcoins. Unlike real currencies, cryptocurrencies only exist online and are not backed by any government or central bank.

  • Cryptocurrencies depend on complex computer software to verify, validate and secure transactions between people exchanging this virtual money online. 

  • Created in 2009. The software running bitcoin was first released in 2009, together with the website, by a programmer self-identified as Satoshi Nakamoto. He announced bitcoin as “a Peer-to-Peer Electronic Cash System”.

  • Taxes. In the US, the government tax collection agency (IRS) defines virtual currencies, including bitcoin, as taxable property (not as a currency). Belarus, by contrast, acknowledges bitcoin as a legal currency in the country and offers cryptocurrency companies a tax break.

How does it work?

  • Blockchain: The financial system to validate bitcoin transactions is known as the blockchain, and depends on a decentralised network of computers connected over the internet.

  • Like peer-to-peer (P2P) networks where unidentified people upload and download music and films, the blockchain depends on a growing community of people and institutions online. 

  • Those peers run bitcoin software to verify bitcoin transactions, independent of any bank or treasury.

  • Every time people exchange bitcoin online, the whole network gets updated with the new information, creating new “blocks”, i.e. long chains of data for computers to solve.

  • Mining farms: As with printing new bank notes, new bitcoins are created by solving “blocks” of mathematical equations that are created each time bitcoins are exchanged online.

  • Bitcoin software can crunch all those equations automatically, but it requires a lot of computing power to do so. For this, large data centres known as “mining farms”, have been set up, with many of the largest farms located in Russia and China.
  • counts 16m bitcoins in circulation, while there can only be up to 21m bitcoins. This limit is set in the Bitcoin algorithm.

Where can you buy it?

  • Bitcoin exchanges. Bitcoins can be purchased through exchange operators dedicated to cryptocurrencies, as well as traditional operators such as the Chicago Mercantile Exchange (CME) and the Swissquote Bank, among others.

  • In those public exchanges, bitcoin is traded under the XBT and BTC symbols. Bitcoin Cash (BCH) is another cryptocurrency with its own price.

  • CME’s Bitcoin Reference Rate (BCC) is a spot price index used by CME and is based on the daily bitcoin price on specialised exchanges such as Bitstamp, GDAX, itBit and Kraken.

  • Costs more than gold. At December’s peak rates, a bitcoin cost as much as $18,000. For this much, you could also buy over 400 grams of gold, at current rates.

  • In 2010, you could buy one bitcoin for less than $0.10. If you had invested $100 then, it would be worth millions today.

How safe an investment is bitcoin?

Investing in bitcoin would mean investing in the complex algorithms on which it is based, and on the future of the peer-to-peer network that operates it. 

Al Jazeera looked at the terms and conditions that an investor in bitcoin would have to accept to buy bitcoin from a Swiss-based exchange operator. Here are some of the risks that you would be accepting as an investor in bitcoin:

  • Price volatility. The value of cryptocurrencies may change significantly even in a single day, which would mean a capital loss of your investment.

  • In December 2017, the price of bitcoin fell by 26 percent. If you had bought a bitcoin on December 19, 2017, you would have paid $18,936 for each coin. But if you wanted to sell it on December 23, buyers on the market were not willing to pay more than $14,048 – a loss of $4,888 for each coin.

  • In January 2018, the value dropped again by more than 10 percent, reaching the $8,000 mark. In February, the price fell below $8,000 and was traded as low as $7,574.20.
  • Other virtual currencies, including ethereum and ripple, also fell sharply. According to, this represented a drop of around $67.7bn in 24 hours. 

  • Cryptocurrencies lack the historical track record of other currencies or commodities, such as gold, that could guide whether current levels of volatility are typical or atypical.

  • Hacking risk. On December 19, 2017, a South Korean cryptocurrency exchange said it would file for bankruptcy after it was hacked for the second time that year. 

  • Over $70m worth of bitcoins has reportedly been lost by several cryptocurrency exchanges and miners, highlighting concerns about the security of such currencies.

  • “Hard fork” splits. Since the value of and support for the currency depend entirely on the community using it, disagreement between the stakeholders may result in the splitting of the network to support new competing cryptocurrencies, this is known as a “hard fork”.

  • For example, Bitcoin Cash (BCH) is a hard fork from the original Bitcoin. Effectively, BCH is now a different cryptocurrency from the original bitcoin, inviting stakeholders to sell their “old” bitcoins and invest in this new one. 

  • The cofounder of the website, Emil Oldenburg, reportedly “sold all my bitcoins recently and switched to Bitcoin Cash”. 

  • Early stage technology. With advances in technology, cryptocurrencies are likely to undergo significant changes in the future. How the existing cryptocurrencies will cope, or benefit, from those changes is to be determined.

  • There is also the risk of alternative technologies that could supersede existing cryptocurrencies and make them obsolete.

Who says what?

  • Vladimir Putin: The Russian president said that cryptocurrencies could be an efficient medium of exchange but warned that they cannot be a store of value and that Russia’s central bank would have to regulate it, as reported by Russian news agency TASS in January 2018.

  • “It is known that the cryptocurrency is not backed by anything. It cannot be a store of value. No material valuables are behind it, and it is not secured by anything.” 

  • “It can be a settlement medium to a certain degree and in certain situations. This is done quickly and efficiently.

  • “This is the prerogative of the central bank at present, and the central bank has sufficient authority so far. However, in broad terms, legislative regulation will be definitely required in future.”

  • Nicolas Maduro: In December 2017 the Venezuelan president announced the creation of a new Petromoneda cryptocurrency – that would be backed by barrels of Venezuelan oil – as a way to circumvent US sanctions.

  • “This cryptocurrency is the future of humanity. Venezuela has entered the future”.

  • Bill Gates: The Microsoft cofounder expressed positive opinions on bitcoin and the underlying blockchain technology in interviews with Bloomberg. 

  • “Bitcoin is better than currency in that you don’t have to be physically in the same place and, of course, for large transactions, currency can get pretty inconvenient.”

  • [Bitcoin] makes moving money between countries easier and getting fees down pretty dramatically, but it won’t be the dominant system.”

  • In Egypt, the Grand Mufti said that cryptocurrency carried risks of “fraudulence, lack of knowledge, and cheating”.

Where you can use it

  • Online stores that accept bitcoin. In 2014, Overstock became the first major online retailer to accept bitcoin payments. Monoprix and Newegg also accept bitcoin online payments.

  • For travel. Latvian airlines AirBaltic and Air Lituanica accept bitcoin payments for some of their flights.

  • California-based online travel booking website claims to have completed more than $1.5m in bitcoin sales on flights, hotel bookings and Amtrak railway bookings.
