Bitcoin really isn't as anonymous and many think it is. Just do a quick Google search.
I read a story a few days ago about some Norwegian guy who bought $27 worth of Bitcoin while writing a research paper on cryptography and forgot about it. When Bitcoin was all over the news he remembered he had some and that investment had turned into over 800K.
I made a small return after buying some Bitcoin (under 5K) and still have a little. I cashed out 4K, spent 2K paying off credit cards, and used the other 2K on some other smaller cryptocurrencies. I don't expect much of a return, if any, but thought it'd be interesting to see what happens.
