It is said now China is a "cashless society". Use of debit cards and credit cards on online & offline stores/shops, pay bills etc..
USA and UK/England are into use of credit cards and debit cards in a big way for online & offline stores/shops, pay bills etc..
Will Bitcoin survive in "cashless society" where money becomes digital/numbers ??
Just like Bitcoin which does not have a physical presence, money/cash will not have physical presence in "cashless society/countries"
Everything can go cashless if everyone agreed to accepting some currency as a payment of their offered sell items, or services.
If the society can managed to get everyone such as buyers and sellers into their community to agree using bitcoin, then cashless society will survived.
