Bitcoin is something that grows in you. And the proof of work philosophy really is a thing.
At some point, you become uncomfortable about holding fiat or fiat related assets (stocks, bonds, ...). Because those aren't really yours. And feels like sponsoring a system you don't support.
At some point, you might have decided to opt out. And move all your savings into Bitcoin. How did you do that?
If you had a significant amount of index funds and wanted to move those to Bitcoin, how would you do it? When?
For the how: probably selling it off slowly for fiat and then Bisq or similar.
For the when: 2 years ago you would have gotten 4x the amount of Bitcoin that you get today for each “share” of the S&P 500. 4 years ago you would have gotten more or less the same that you would today. https://inflationchart.com/spx-in-btc/?time=5%20years&show_stock=0&show_adjuster=0&zero=1 Would you wait for another SP500/BTC peak?
Did you move all your savings into Bitcoin? How did you do so? How would you do it today?
