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"
Bitcoin is an alternative, but not a replacement. These two currencies are dependent. First of all, bitcoin is from Fiat. The Fiat currency, in turn, can safely exist without bitcoin, but alas, it becomes digital very quickly. Digitization is inevitable!
