Most countries have a fiat currency model, meaning controlling the value of the money. Technically, the money never leaves a bank. Simply, as the value of money is defined by central bank, you won’t have any control over it, which may act out of your preferred interest. However, decentralized cryptocurrency work differently. The coin’s value is determined through the authority of the end consumer, and it cannot be changed. So, we have blockchain technology providing security and encryption to cryptocurrencies.
