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"
Unlikely because there are too many Altcoins in Cryptocurrency, we need to unify Altcoin used to pay this will limit the distribution. But FIAT is more direct and more comfortable in transactions if there is no Internet. Without internet, all Altcoin will be completely useless.
