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.
Ofcourse yes, bitcoin is a good example of cashless society in just one click they are paid to thier purchase. But it only happen if any store accept Bitcoin as payment, once Bitcoin accept as payment surely all transactions will be more faster. Therefore Bitcoin can survive in cashless society and I think it is much convenient to used than using credit or debit cards. But I think if you have bitcoin its better to hold it than used it as payment because its value is unstable, so it mean there's time its value is lower and sometimes higher.
