Cryptocurrencies that have entered our lives since 2009 have spread around the world in a short period because they are not affiliated with any authority and are anonymous. Today, especially in developed countries, spending is mostly done with digital money rather than paper money. Digital money stands for paper money, which is stored electronically and has transferable properties. Although there are nearly a thousand different cryptocurrencies today, the exact number is unknown.
