I think so much that distinguishes between real money and bitcoin. transactions using real money, I think is happening so fast, because it occurs directly. today, bitcoin transaction to be so slow. so, it is one difference.
That can be one difference but technically there are so many differences like the price of currency doesn't increase even if it increases it doesn't make any difference while bitcoins price keeps changing time to time.
Well that was a big difference money is stable one and bitcoin is keep changing in time to time..
But if there is no money bitcoin has no value.. so they are both important.. and we are getting benefits of the price increase of bitcoin while we are exchanging it into real money if the price is low again we can buy again using real money. so each of one has role and they are both important.
Eventually, we will not be depending on fiat money. 10k$ per coin is a clear indicator that a lot of people are already using bitcoins and merchants are starting to accept it. At that time, even when money has no value, bitcoin would still have value because the prices of items for sale will be based on bitcoins.
