This site is overwhelmingly negative towards Bitcoin, but I feel like the negativity would only make sense if you had to make a binary decision to put most of your wealth in Bitcoin or none of it.
Having just some Bitcoin say 5%, is a reasonable way to preserve your wealth against what I find to be a very opaque system of finance where a lot of trust is being placed in a handful of people to keep things running smoothly.
If the U.S. government, the Federal Reserve, some crazy trade-conflict or other global unforeseen event takes place that results in unusual currency fluctuations, it's nice to have some of my wealth contained in a digitally secure global financial system.
