I made ~ 20k in 08 s recession; Siemens stock dropped to $35 in the spring, and I bought 2500 shares. Then by september it was back up to ~140,so I sold them for the profits.
I have to get my DRIP setup so I don't have to do this manually anymore. Not sure how to handle it in the Fidelity app. But at the same time, I'm not putting in the time to research on how to do it
Funnily enough I was mining ZEC casually 7 or 8 years ago (when the ROI exceeded the cost of electricity) and after I cashed out, I had enough to pay for the electricity, GPUs, and a little to put towards flying.
The remnants of what I didn't cash out I used to trade in the exchange. Never really got the hang of it, so I left it. A year or two ago I decided to convert what ZEC I had left for BTC, and that was when BTC was down around $28k. So I'm happy.
