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.
If you are talking about the amount probably it is bitcoin, but reliability was on cash you dont have to open wifi then send btc for exchange or for payment , it is accessible also, maybe when it comes to profit of course bitcoin is above but then bitcoin has its own limitation withoit internet you cannot access it right? And paper money has it also it may taken away with you, it is stable, in which unlik bitcoin it !ay raise it value unlike in paper money it doesnt.
