It seems that Bitcoin's problems are starting to increase with congestion on the Bitcoin network and transaction fees that are also increasing. Currency or whatever it is, fiat and bitcoin still depend on each other but are still in their respective realms. This depends on the user and the benefits of bitcoin and fiat itself. Even in remote areas, we cannot freely use Bitcoin if our transaction partner does not know or is reluctant to use Bitcoin, it is the same as Bitcoin being useless in that place and fiat money is still a more useful tool. It is appropriate for Fiat and Bitcoin to work together now and into the future.
