Blockchain and Cryptocurrency
as the digital representation of value that can be stored or sold, accepted as a medium
of exchange by individuals and transferred electronically, but there is no central bank
or public authority behind it, and it is not linked to a fiat currency. Cryptocurrencies,
as the name suggests, are coins created with cryptographic encryption methods.
Within the scope of the security provided by the encryption methods used, it is not
possible to imitate, use and create illegal cryptocurrencies (Coron, 2006; Urquhart,
2016; Vigna & Casey, 2016; Garratt & Wallace, 2018).
2.4 COMPARISON OF CRYPTOCURRENCY AND MONEY
One of the important focuses of cryptocurrency discussions is whether cryptocur
rencies are really money. In this respect, the easiest and most effective way is to
look at cryptocurrencies in terms of the features and functions of money (Howells &
Bain, 2008; Griffith, 2017; Vigna & Casey, 2016).
When money is mentioned, six different features come to mind: Portability, dura
bility, divisibility, homogeneity, non-imitation and stability. In terms of portability, it
can be said that cryptocurrencies can be transported more easily than money, since
they are in a format that can be integrated into all mobile devices by using them in
a digital environment. Money can deform over time due to its physical nature and
use. However, cryptocurrencies are not physically minted and used. In this way, it
can be said that cryptocurrencies are more durable than money. It can also be said
that cryptocurrencies are more advantageous in terms of divisibility features. While
cryptocurrencies have the ability to be divided into one cryptocurrency in a hundred
million, this is not possible with money. From the point of view of the non-imitation
feature, it is clear that imitation of cryptocurrencies produced with cryptographic
encryption is more difficult than it is with money. In terms of the features of money,
the most controversial issue is the ability to maintain its value over time, namely,
stability. As stated before, there are many cryptocurrencies, and their values are very
volatile. It is not yet possible to talk about a mature and stable process. The value
of a cryptocurrency may clearly decrease or increase due to external effects. At this
point, it is not yet possible to say that cryptocurrencies are superior to any money.
Money has three basic functions: A medium of exchange, a unit of account and
a store of value. In daily economic life, money is widely accepted as a medium of
exchange and used in return for the purchase of goods and services. Although it is
a fact that cryptocurrencies are used more in the purchase of goods and services
in the real economy than when they first appeared, this is far from saying that it is
generally accepted. The fact that cryptocurrencies have not yet reached legal status
and have high volatility limits the use of cryptocurrencies in the sale and purchase
of goods and services by consumers and sellers. In this respect, it can be said that
cryptocurrency has come a long way towards becoming a medium of exchange, but
it is not yet a generally accepted medium of exchange. The second function of money
is as a unit of account. This function enables the comparison of the relative values
of goods and services by using money as a common unit of measure in the purchase
and sale of goods and services. At present, the wide variety of cryptocurrencies and
their very variable values make it very difficult to use them as a unit of account. In
