Crypto are digital assets, also known as cryptocurrencies. Cryptocurrencies are digital currencies that are decentralized, encrypted and usually created using blockchain technology. Bitcoin, the most popular cryptocurrency, was created in 2009. Since then, Ethereum, Ripple, Litecoin and thousands of other cryptocurrencies have been launched.

So, what is blockchain? Blockchain can be thought of as a digital ledger consisting of a series of blocks of information. These blocks of information are linked to each other in a chained way and are therefore called “blockchain”. To give an example, imagine that a notebook is used to keep track of pocket money among a group of friends. Everyone writes down the pocket money they spend and receive in this book. Each page in the notebook is similar to a block and each page is linked to the previous page.

Each block in the blockchain contains a certain amount of transactions (e.g. money transfers) and these transactions are stored in an encrypted form. When a block is full, a new block containing new operations is created and connected to the previous block. Since this connection is made using a special mathematical process (cryptography), it is virtually impossible to change the order of the blocks or manipulate their contents. Thanks to this structure, blockchain is a secure and transparent system of records. Transactions are visible to everyone, but cannot be changed. This technology is used in areas such as cryptocurrencies, but it can also be used for other purposes: like storing contracts or medical records.

Now, after this brief explanation of blockchain, let’s turn to the use of cryptocurrencies:

  1. As a means of payment: Cryptocurrencies can be used to pay for goods and services. Many businesses and retailers allow customers to pay with cryptocurrencies.
  2. As an investment instrument: Cryptocurrencies also offer an option for those who want to invest. Cryptocurrency investors aim to make a profit by investing in cryptocurrencies that they believe will increase in value.
  3. Money transfers: Cryptocurrencies can be used to make money transfers quickly and cost-effectively around the world.


  1. Decentralized structure: Cryptocurrencies are traded independently of central authorities and retain their value. This means that governments and banks cannot have direct control over cryptocurrencies.
  2. Low transaction fees: Transactions using cryptocurrencies usually involve low transaction fees.
  3. Fast transactions: Cryptocurrency transfers are faster than traditional banking transactions.
  4. Transparency: Thanks to blockchain technology, cryptocurrency transactions are transparent and easy to track.


  1. Price volatility: The value of cryptocurrencies can fluctuate greatly over short periods of time. This creates risk for investors and users.
  2. Security risks: While most cryptocurrencies are secure, in some cases they are susceptible to cyberattacks and theft.
  3. Legal regulations: The legal status and regulations of cryptocurrencies vary from country to country. This creates uncertainty for users.

So, what awaits us in the future of cryptocurrencies and technological developments?

  1. Faster transactions: Current cryptocurrencies can sometimes take a long time to complete transactions. In the future, we may see cryptocurrencies with faster transaction times. Thus, paying with digital coins will be much easier and faster.
  2. More environmentally friendly: Some cryptocurrencies use energy-intensive methods to verify transactions. In the future, we can expect to see cryptocurrencies that are more energy efficient and environmentally friendly.
  3. Easier to use: Cryptocurrencies can sometimes be complicated to use at the moment. In the future, we can expect more simple and user-friendly applications and services for using and storing cryptocurrencies.
  4. More security: The security of cryptocurrencies is important and we may see more secure cryptocurrency systems in the future. This will allow cryptocurrencies to be used more reliably.
  5. More acceptance: In the future, more businesses and service providers may start accepting cryptocurrencies as a payment method. This will help cryptocurrencies become more mainstream in everyday life.

These technological developments may contribute to the future of cryptocurrencies by providing a more user-friendly, fast and secure experience.
