It's true that Bitcoin has seen incredible gains over the last 10 years, but that's not to say that saving in dollars is always a bad idea. While Bitcoin has certainly made some people a lot of money, it's still a relatively new and volatile currency that is subject to significant price fluctuations. It's important to always do your research and consider the risks before investing in any asset, including Bitcoin. That being said, I'm glad to hear that Bitcoin has worked out well for you!
