If anyone ever tries to tell you they always buy and sell investments at just the right time, get ready for them to try to sell you a bridge somewhere. You did what was right for you at the time. Judging your former self with your current knowledge is literally like being mad at yourself for not predicting the future. I've only recently found Steemit, so look at it this way, while you were cashing out and getting something, I was posting on other social media sites not even knowing what I was missing. :-)
