NO
If both bitcoin and traditional currencies exist I think it will be better, the fact that they're things that can not be purchase using btc, what I mean is that they are things that are very cheap if we should use bitcoin in such things I think even the transactions fees cost more than what we intend to buy sometimes so you can see that if we use the both it will be good and the fact that they are must countries that can never accept bitcoin as a legal tender, so in my opinion, it will be hard for bitcoin to replace traditional currencies.

However, I believe that bitcoin payments should be made when purchasing expensive items, such as when shopping or placing an online order. If they accept bitcoin as part of the payment, you can do that. However, not all businessmen are familiar with bitcoin and are not even willing to learn it, so you can see that bitcoin cannot completely replace traditional currencies.
