How do cryptocurrencies differ from conventional currencies?
The main difference between cryptocurrencies and conventional ones is the way in which money is created and regulated.
Conventional money is issued and regulated by a central bank based on a system of investments and debts.
By contrast, cryptocurrencies are completely free and independent of banks, payment service providers and state regulatory authorities.
Since cryptocurrency reserves cannot be increased ad infinitum (like paper money) but are instead limited to a maximum number, the cryptocurrency system is also protected from inflation.
