    New version of Nostr VPN is out. Like tailscale, but no email addresses or 3rd party accounts, just public keys. New: * native multiplatform user interfaces * Nostr-based multihop routing (FIPS protocol) — very useful when NAT holepunching fails * improved network management UX

    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.

    Thank you, Satoshi and others who have made Bitcoin what it is today. May it bring peace and prosperity to the world. Long live Bitcoin.

    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.

    Found the first known bitcoin to USD transaction from my email backups. I sold 5,050 BTC for $5,02 on 2009-10-12.

    Finland, like most European countries, needs a political and cultural U-turn like we've seen in U.S., Argentina and El Salvador. Deregulation and public spending cuts like we've never seen before. Healthy pride in Western values instead of woke culture. How do we make it happen?

    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.

    I quit a boring job as a junior software developer and went to study Japanese for a couple months in Fukuoka, Japan. Also visited the Tokyo office of Mt. Gox when they were still doing great. Tokyo sunset from the office:

    Satoshi downplayed his writing, but as evident from the emails, his English was perfect, much better than mine. I don't remember a single instance where he even made a spelling error.

    Nope. Bitcoin was announced on the cryptography mailing list in January 2009 and many people could have tested it. I found Bitcoin around April. @Cointelegraph
