Fiat remains more important to most parts of the world than bitcoin, many bitcoiners have their bitcoin sitting in their wallets while they use fiat for their daily transactions, bitcoin is freedom yes, but it is more of a freedom asset now than a freedom money because it is not so much accepted as a medium of exchange in so many places. Majestic-milf i can be certain you will use fiat today, but i can say the same for bitcoin. When bitcoin becomes a popular medium of exchange around the world and people use it as money for daily transactions, then it can in the complete sense be freedom money.
Bitcoin is a freedom currency in terms of management. But for exchanges in terms of comparison with fiat currency, bitcoin is still far from all this stuff indecencies it has gathered firms. Yes of course cryptocurrency has much firms in the world currently but not all the countries Bitcoin is allowed to operate. And not everything Bitcoin can purchase in every nation. It still have alot of ways to go irrespective of it adoption and it recognition in the world,bitcoin still can't be popular as fiat currency.
I think it will never be possible to use fiat to buy itmes across the the world. Bitcoin is more an asset than a currency.
It's like wanting to pay with gold for your groceries. It will never happen.
Other crypto could be used as common currencies. But I think we will see stablecoins doing that. And not assets with high volatility like ETH or BTC.
