> The fact that you're comparing Visa with Bitcoin is exactly my point: Humans make decisions based on the things they can immediately see and neglect things they can't see. That's what you're doing when you're comparing visa to bitcoin.

Then can you explain the economic utility that bitcoin provides because it is more innificient way to store and exchange "value" than what banks provide?

> I can't really explain this in a single HN comment, which is why I recommended studying economics. If this was so easy that I could explain it in a page nobody would need to read books or take classes.

I have taken many econ classes and I have read dozens of econ textbooks. You are handwaving about "ripple effects" and that if I knew econ it would all make sense.

Let me ask you back. Can you prove with 100% certainty that banks are more "efficient" than bitcoin? What does "efficient" even mean? Did you take into account all the jobs required to run the banks? Did you take into account all the energy these bank employees consume? Did you take into account all the side industries that arise around banking system? Did you take into account all the corruption that took place over and over and over throughout history that eventually took everything down to zero? This question is really meaningless when you consider all these factors.

People tend to arrogantly think that they understand the world when they don't. All they do is try their best to make sense of things, and even with these scientific theories, nothing is absolute. Note that I'm not calling YOU arrogant. I'm calling humans as a whole.

I am not saying PoW is better. I'm saying people who think PoS is absolutely better than PoW are leaving a lot of things out of the picture when they draw that conclusion. Nobody knows what's better or what's more efficient. Maybe banking IS more efficient, but maybe in the long term (as in 100 years) it may be more inefficient. (History shows that there's A LOT of invisible inefficiency in the banking system, manifested as economic depressions)

What? I thought you said you were well versed in economics. This is literally one of the core concepts for the benefits of economics because you can evaluate things on their "efficiency" (costs) versus the value they provide (revenue). Every "job", "energy cost", and "side industries that arise around banking system" are evaluated in the cost to run the business and if they were greater than the value they provided, they would not be in bunessines because revenue would be less than sum of those costs.

Obviously corruption is not good for our systems neither are other economic problems such as negative externalities [0]. However, I don't see how cryptocurrencies solve them in a way that makes them better than current solutions as a whole.

I'm not asking you to write a phd. Just give me one good economic use case outside of illegal markets for cryptocurrencies that is better than current technological solutions.

Transfer $1000 from your Coinbase (or other electronic) account in the US to cash in Indonesia, in less than 20 minutes, at a better rate than spot. I did it yesterday with ETH and even made $20 on the spread after all the fees.

The cheapest conventional alternative would have been a Visa or Plus ATM card which would have cost around $14-$47 depending on how good your card is.

You may have found one temporary use case but I don't expect that to last if cryptocurrencies gain in value.

How much did it cost to exchange USD -> crypto -> Indonesia money?

[aianus]

I used limit orders to add liquidity in both countries and so paid no trading fees. There was a 1% “cash withdrawal fee” at the Indonesian exchange which is all I paid in total.

I don’t know how temporary it will be; I’ve been using crypto to transfer money internationally since 2013 when BTC was $800 and it’s always been the cheapest method (although I sometimes had to write bots and wait a few days to get a good deal). I imagine the spreads will continue to trend towards zero so I’ll be paying 0-1.5% total instead of earning 2% which is still much better than banks for three-figure to low four-figure amounts.
