It is said now China is a cashless society. Use of debit and credit cards in shops/stores, online pay bills, shopping online.
Money earned from the internet is known as digital/electronic money. People who earn money from the internet, they get paid money in electronic form by payment processors such as skrill, perfectmoney, alipay, paypal, bank-wire transfers because online workers are worldwide.
Last month, I got $20 from online surveys. The money was sent to my bank account via online payment processor. Now if I buy 2 shirts using debit cards at offline or online stores, there is no cash involved but I have 2 shirts.
Just like Bitcoin which does not have a physical presence, money/cash will not have physical presence in "cashless society/countries" where money becomes digital/numbers.
Bitcoin is a part of digital money. How is digital money is your country ??
Debit/credit cards are limited in terms of partnership, there are stores that is not in relation in some other banks. A good example of cashless society is your phone or gadget will be your wallet or the most special is your wallet is stored in the internet which you can access anywhere. In our country (Philippines) we can't use all kinds of crypto for payment( limited type), we have to convert to fiat to make use of it.
