It is amazing to tell about the crypto currency. 
you know about the currencies which are being used in different countries with various names like Dollars, Pound, Rupees , Yen, Rubble etc. Every currency in the world has gone through different ages and been used by the different generations passed by . It has got into different shapes and position and values according to the use of the particular country . Currency has power over every society and families.
Currency is nothing but a transaction between people. It helps us to meet the needs of the two parties. based on the needs, currency has great role over every human being.
As the transaction has gone through different shapes now crypto currency has come with another shape of technology. As the age is running with technology, crypto currency is a styem of transaction.
