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"
The answer is YES, as we already know that the main purpose of bitcoin has been made is to become a currency without cash. We can imagine how easier using bitcoin or things that is not using cash to pay something. Just move your digital number into another wallet.
