It seems to me that so far fiat bitcoins are indeed these currencies that are necessary and indispensable.
What are you saying ? what is FIAT BITCOIN? do you really understand what are you saying here?the question is about the comparison of Fiat or Bitcoin and not them both bonding together
Fiat money and bitcoin are two different components, but due to the fact that bitcoin is separated from the state - this is 100%, I would even say that cryptocurrency cannot be controlled and the more it develops, the more I need to control it ... Fiat is needed in its own way, bitcoin is needed in its own way, the state of bitcoin is currently beneficial to all parties.
Not in all parties specially when there are congestion happening when the transaction fees climbing so high that small transactions are really affected.
