All you have mentioned above was right, these are the best advantage of crypto that could be consider better than fiat.
All could be smooth and fast trasaction across borders and easy to use wherever you are, you also have a free to control your fund, not at least you are already a billionaire. Traditional money is not traceable once a holder wanted to have a transaction. Nevertheless, both these two currency can not be compared.
Ho wever, bitcoin may have an advantage because it can also be used as an asset or investment but with fiat, it only serves as a payment purposes. But bitcoin does not aim to overtake fiat as they exist both as a mode of payment.
I think Bitcoin is better than fiat, because Bitcoin can not only be used for payments, but Bitcoin is very good as an asset too. It's ideal that
we have both, because until now, I'm more comfortable using fiat to make payments. Bitcoin is only an alternative to payments, moreover,
its volatile price makes Bitcoin ineffective for payments. Actually, the purpose of Bitcoin from the start was not to replace fiat, but as an alternative
to fiat. So that people have more choices when it comes to making payments, so I really hope that both exist and can complement each other.
