I share that concern. I just turned the bitcoin that I had been purchasing since 2014 into dollars.
The best thing to do is to research bitcoin. Learn how it works. Try to understand Satoshi Nakamoto’s motivation to create it. Read the Bitcoin White Paper. Find out why people enjoy using it. Look for other blockchain technologies, see what they do better than or worse than bitcoin. After you get a good understanding of it, then decide whether bitcoin will be useful in your personal life or not. That’s ultimately the best reason to have any, is if it is useful. I generally advise against buying to make more dollars, since the idea behind bitcoin was to replace dollars and other blood-soaked currencies.
