Despite much opinion to the contrary, the government money we use is crappy.
I'm at bitfest in Manchester to find out if Bitcoin could be a better money.
It could hardly be worse.
The mood is still good, people are joking about recent devaluation rather than crying. Those who aren't all in are trying to buy more at the discount.
After an introduction by Mad Bitcoins, Joe Bryan explains the problem with government money.
He imagines an island on which two types of money are tried, with a dividing wall between them.
When economic problems hit, government can just print more money on the fiat side. Everyone now using money which is worth less. Distorting prices, inflating asset prices, making the rich (who hold assets) richer and the poor (who have to pay inflated prices) poorer. Driving wealth inequality.
On the hard money side, government must tax properly. Take in more from the rich rather than inflating to take it from the poor. Reducing wealth inequality.
On the government money side, the wealthy monitize houses, stocks, resources. Saving in money is impossible, its inflated away. So they save in assets and hording resources. Capital is misallocated. The youth can't afford houses. Poverty traps are caused. The only way out is printing more for benefits. Making it all worse. More economic crises, more printing. More government debt.
Eventually, the wall is broken. Government money people can save in the hard money instead. It reduces the value of government money further. More printing. More inflation.
Eventually, war. Funded by printed money.
The dollar is the best of a bad bunch all other government money is falling in value even faster.
I wonder, is bitcoin really this better money though? It's limited, hard, and can't be printed without energy investment.
I'm still unsure that fixing money fixes the world.

Note: "crypto" is mostly more like government money than bitcoin. It can be printed indefinitely by it's makers, does not cost it's makers to print. Crypto is usually just a scam people to get more bitcoin. Bitcoin is not crypto.

My mother is incredible.
We like to joke that she is a model #immigrant:
- She came to the #US fleeing from the war in #Ukraine, with no further plan besides getting to me and my husband in at least temporary safety.
- We had to run a crowdfunding campaign to help her and the kids sustain themselves as they waited for their #TPS immigration paperwork to process.
- Once her work authorization came through, she somehow managed to get a job as faculty at #Cornell - and started their #Ukrainian program, teaching the language and Ukrainian history for the first time in the university’s curriculum.
- Now she’s been accepted to academic conferences, publications, and has joined the board of the refugee support organization in #Ithaca that helped her get settled there herself.
I’m so proud of her. Y’all should read this article, it’s pretty good: https://www.ithacawelcomesrefugees.org/giving-from-abundance-krystynas-journey-to-becoming-an-iwr-board-member/
