I prefer to use cryptocurrency more than fiat because is faster, safer and with the recent spread of the deadly coronavirus you can be rest assured that the use of fiat currencies has several disadvantages. I can't use cryptocurrencies that much for any transaction because it's barely used in my country but i believe in the near future cryptocurrencies would take over the payment system.
Well said mate, the transaction with cryptocurrency is much safer, less hassle, and faster compared to the fiat currency because the deal happens online, so there is no traffic that you may encounter, only connection or slow internet connectivity can be causes of the delay transactions.
Speaking of coronavirus or other viruses that our world may encounter, cryptocurrency would also be better because you don't need to go outside anymore when you are going to pay bills and other transactions that you may have. There are a lot of workers that may be affected when coronavirus happened, there are a lot of people whos afraid of going outside to work on a company because of the virus.
