I always wonder how could an economy operate and run without taxes from cryptocurrencies. How could a government obtain taxes from people when people are completely utilizing a currency that is not supporting taxes. Would it be really good if we completely have our fiats converted to crypto? For me, there's always a way if our intention is good. We cannot really deny how government is providing regulation that is mainly for the betterment of us despite of some issues regarding corruption and frauds.
For me, the way we could still make it possible is to establish a local exchange wherein, if we convert our money to crypto, these local exchange could already have the portion intended for the tax of each transactions.
I think it would be utterly ridiculous to convert all of ones money into cryptocurrencies, unless one wanted to loss the shirt off of his/her back and then some.
Cryptocurrency is way too volatile to dump an entire Bank account into it. Are cryptocurrencies the future, almost certainly, whether or not Bitcoin will still be around is highly debatable, but Fiat really isn't going anywhere anytime soon, you can count on that.
Maybe within the future once regulations and policies are much clearer for everyone involved, but to each his/her own! Fiat is way too easy to use whether physically or digitally, try explaining Bitcoin and Blockchain technology to my grandparents, they'll laugh at you then ask you does your president or local Congressmen support it? If not, it's probably a no go!
