Now that more and more countries are starting to go cashless (
http://www.bbc.com/capital/story/20180427-does-a-cashless-society-benefit-everyone), is it possible that we also start converting to cryptocurrency? If that happens, what do you think are the advantages and disadvantages? Paying virtually is very convenient for me as I do not have to bring cash and it prevents petty theft but what is the disadvantage?
The main disadvantage of crypto is that it's still highly volatile meaning that its value with respect to goods and services bought is unstable. I know I'm saying unpopular thing but there should be some kind of regulation to make crypto more stable if we want it to be used a a currency in the direct meaning of this word.
Let me clear for you when you send money via banks you pay tax which help for the benefit for your country where bitcoin is tax free you won't pay tax which mean government gain nothing with your transaction.
