in the future, will there really be a need for fiat currency? Government can collect taxes in crypto, determine how to allocate it, and spend it in crypto. Ppl can receive salaries and do all commerce using crypto. Loans can be done in crypto. Fundraising can be in crypto. Sure, problems have to be worked out in terms of scalability, does it have to be completely decentralized, etc, the value has to become more stable. But theoretically, is there any reason to have fiat in the future?
It has been established that governments can now do taxation without representation by printing more money (which is a tax on everyone holding the currency), instead of trying to get a bill passed that allows it to increase the tax rate. With crypto this would be no more. All increased taxation would have to pass a vote.
From an economic standpoint, the idea that a country can stimulate its economy by adjusting interest rates is tenuous. There is just as strong an argument that lowering interest rates has caused speculation and bubbles, with calamitous results. In a crypto market economy, capital will flow from where it is needed less to where it is needed more.
While FIAT has been going strong for quite a while, you gotta remember that FIAT didn't exist before, and its mass adoption was due to how simpler FIAT made things. With advances in ourselves as societies and as new technologies are being developed, I believe that yes, eventually, something better/faster/easier than FIAT can and will replace it. Is it crypto though? I wish. That'd mean we get to tell everyone "I told you so!".
Jokes aside, and building on that "something better/faster/easier" that I mentioned earlier, I wanted to share a piece of info that you guys might find interesting, this just an excerpt:
"A federal science agency in Australia has claimed a world first after completing testing on a global blockchain network that is capable of processing 30,000 cross-border transactions per second.
If the test can be successfully carried into a working model, it could help the banking industry attain the scale needed to put blockchain networks into the mainstream.
The network, called Red Belly Blockchain, was developed by the Commonwealth Scientific and Research Organisation (CSIRO) and the University of Sydney, and deployed over the Amazon Web Services (AWS) global cloud infrastructure. It was tested across 1,000 nodes in 14 countries at a benchmark rate of 30,000 transactions per second and with an average latency of three seconds.
According to the developers, the network hopes to solve the scalability issue by using an alternative consensus algorithm instead of the proof-of-work mechanism adopted by most public networks, including bitcoin."Now I feel that news like this are gigantic for the crypto world because if there's something crypto kinda fails at is at scaling, there's issues with scale, now, to completely phase FIAT away I think crypto should first take care of its own inner workings and make sure it has the capacity to run the world's worth of transactions in the blockchain, and then, FIAT will disappear out of lack of use. At least that's what I think.
