I'd be a *billionaire* now if I hadn't sold the 55,000 bitcoins I mined on my laptop in 2009-2010 way too early (mostly before 2012). That is regretful, but then again, with the early bitcoiners we set in motion something greater than personal gain.

Some lessons learned: 1) Money matters: more is always better than less. 2) Still, you don't need to be rich to lead a perfectly good life. It's about the basic things. 3) You don't live forever. Pursuing something greater than yourself brings meaning in life.

In 2011 when the exchange rate peaked at $15-$30, I sold over 10,000 BTC to buy a fairly comfortable studio apartment near Helsinki. Big deal for a 22-year-old who never had much money. Probably the most expensive studio in the world now, but at least I got more than 2 pizzas.

Perhaps owing to Finnish culture, idealistic mentality and lack of life experience, I never thought much about making money. It happened accidentally as a byproduct of Satoshi asking me to keep my node running so others could connect. Thank you, Satoshi.

”Money doesn’t work that way” - getting rejected or ignored was indeed the usual reaction to bitcoin back in the day. Bitcoin’s success forced ppl to re-evaluate their conceptions about money and other things, such as the authority of ”experts” in some fields.

@serumroth @RajarshiMaitra @BobMcElrath @adam3us There is tons of bizarre fantasy in the OT, but one of the things wrong with it is that a non-official & decentralized currency was politically & economically a very fringe idea. All economists of all stripes, including Austrian, who heard the idea either ignored or rejected it.

Of course, it would have been possible and fun to *also* get rich while being an idealist. Then you could invest and donate to advance the cause (while driving a sports car). But thanks to Bitcoin, many people are taking care of just that.

In late 2010 there was an influx of bitcoiners who were only interested in mining. That's not wrong by any means, just different than the idealist ethos. Bitcoin had the right incentives for growth.

If commodities were traded for BTC on a DEX, could we use the market prices to establish a "basket currency" — a derivative unit of account that is relatively stable and can be used for pricing instead of USD? Its BTC value could be independently verified from the DEX.
