The development of cryptocurrencies has brought a major change in the world of online transactions. Before the year 2009, almost all the online transactions were done either through Paypal, credit cards, or checks. Some people used bank transfer options when it comes to making payments before Bitcoin was invented. However, now it seems that cryptocurrencies have also changed the internet and modes of payments. There are many websites that are now accepting Bitcoin and other cryptocurrencies as payment methods. However, cryptocurrencies are very difficult to trace and it is believed that cryptocurrencies are nearly untraceable to some extent. However, why is it so difficult to track or trace the person who sent or received cryptos? What makes crypto untraceable? I am not a crypto expert, so this question needs to be addressed.
