> 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?

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.

> 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?

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.

> This question is really meaningless when you consider all these factors.

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.
