I don't know if this thread has been created before, but I would like to know your opinion on Cryptocurrency versus Fiat.
If you could tell me why too. What are the benefit of each?

Each of them fiat and crypto has its own place in our lifes, sometimes it is better to make payments on bitcoin rather on fiat because of the time that takes but also the fees which are much lower on bitcoin.
If you need to pay in fiat through credit card then it is a good way to use paypal to cover the card details and more secure.
