Something strange with TradingView that I didn't understand. But it's not 270% the last two years, when I added up 2 years with measurement tools, one per year. But then it didn't calculate the "interest-on-interest effect" correctly. So since 2022-12-26, Bitcoin has gone up +460%. Sounds a little better than +270%.

Concerned big brother: "How's it going with your Bitcoin?" Me: "Gone up +270% last two years and down -1% this year so far. Doing all right, thank you."
