How interesting this sounds, but a lot need to be put in place before this could be achieved, in short, we are not there yet–no–not at this time could we live solely on cryptocurrency. Many Government body in the world haven't even accepted (legalise) cryptocurrency to be used as a medium of exchange in their countries–with this, how easy would it be to live solely on it?

Until cryptocurrency is legalised in our various countries and generally accepted in all the places where our daily needs reside (manufacturers, retailers and most importantly wholesalers), it will be most impossible to live solely on cryptocurrencies.

I've been wondering, is there a way to live by crypto alone and stay away from Fiat? 

So far, it is difficult. Except your country legalize crypto as a currency and there are many merchants that accept crypto as payment and most people around you are familiar with and using crypto. If none of these, it will be very difficult to realize it.

Everyone is talking about privacy and decentralization but Fiat is breaking that boundary always, the moment you want Fiat after having some crypto your privacy is ruined.

exactly, but we also know that decentralization and centralization also have their positive and negative sides. And most people who are against crypto is because they stay for centralization that is considered to have more security and there is a guarantee from the government and also responsible parties, different with crypto that doesn't have it.

Maybe in the future not now fiat is still the current rulling moneytory system in place.

Everyone is talking about privacy and decentralization but Fiat is breaking that boundary always, the moment you want Fiat after having some crypto your privacy is ruined.

Then you should stay away from using any centralized exchanges and make use decentralized exchange to secure your data.

Is it possible to use crypto without fiat? Definitely not. It is impossible to live on Bitcoin or any other altcoin without fiat currency. The advantages of digital assets over fiat currencies include transaction security and high levels of transparency, but our current system is broken and old-fashioned, so it is very difficult to change. While most of us talk about privacy and decentralization, the fact is that you can't totally get rid of centralization.

Find a way to become a professional crypto trader then your survival can be on crypto alone, still you will get to the point where Fiat is a necessity, there are billions of businesses and stores out there that doesn't care about the existence of crypto, they will always give you a NO as answer when you ask if you can pay using crypto, maybe very soon or some day but right now Crypto isn't there yet.
