The advantages of cryptocurrency include the following positive points:
Availability of cryptocurrency - electronic money at any time.
At the same time, it is impossible to freeze an account or withdraw cryptocurrency.
At any time, you can check the validity of the operations performed.
Code openness. Thanks to this feature, anyone can mine virtual coins.
Anonymity. Unlike classical electronic money, transactions with which are easily tracked, it will not be possible to obtain information about the owner of a cryptocurrency wallet. Only the wallet number and limited data on the amount in the account are available.
Reliability. It will not work to hack, fake or carry out other similar manipulations with virtual currency - it is reliably protected.
In most cases, the commission is charged exclusively on a voluntary basis.
Cryptocurrency limitation. As a rule, the cryptocurrency is issued in a limited volume, which attracts increased attention from investors and eliminates the risk of inflation due to the excessive activity of the issuer. Thus, the cryptocurrency is not subject to inflation and is inherently a deflationary currency.
Cryptocurrency is an independent monetary unit. No one regulates its issue and no one controls the movement of funds on the account. It is this feature that attracts many members of the Network.
There is no commission for transferring funds between countries.
