In a short time the fiat money will disappear and Bitcoin with other cryptocurrencies will take over. By the time the bigger industries get involve in digital currency, then the Fiat money will be no more........
How could you say so? Because of its price? Well it wont happen that fast. Bitcoin cant replaced fiat currency. It still under it, remember the usage of the two and bitcoin does not accept all over the world, in fact some country already banned it. Not all people like bitcoin even they knew it so it cant make fiat currency disappear becauae people will still choose it than bitcoin. Better to look ok different side before you say that thing.
Real money is the clear winner.Real money is used by every person on the earth while bitcoin is used by only a small percentage of people only.Moreover bitcoin requires internet accessibility to get operated while real money can be used anywhere and anytime.Bitcoin is also decentralised and very volatile.On the other hand real money is centralised and stable and also government protects its power.Bitcoin cannot overtake real money at any cost.
