Electronic money doesnt rotate on just bitcoins or cryptocurrencies,be mindful that us dollars and other currency can now be use in an online wallet which works same as cryptocurrencies.But comparing electronic currency and physical money i would rather have electronic money because its more convinient
I agree, by using electronic money like creditcards is much better because you can't lose your money because it is all online and if you lose your wallet you just get yourself a new card and that is it. No one can steal your money but with physical money someone can buy things with it.
