Bitcoin is always better than cash.For our bitcoin earnings,we are not accountable to government and we need not have to pay taxes unless it is legalized in the particular country.With bitcoin,we could easily send huge amounts of money with very low fee at high speed.With bitcoin,our money value increases,but with cash,our money just remains idle.
As a bitcoin user I think that bitcoin is better than cash in some manners. Bitcoin doesnt need tax for a money transactions. Easier and less hustle than going to bank and wait. And it can always bring anywhere you want and anytime you need.
