The worst thing I ever did was sell my bitcoin at a very cheap price I had a huge loss. My mental and emotional level is an important part of taking every decision.
It's true - the ability to take emotion out of trading is paramount to being a successful trader. It's definitely easier said than done, though. Hell, even hodling can be hard when the market dives!
Same here bud, as what I've been experienced on my bitcoin way back last November 2017. On that time I'm planning to hold my shares which that time bitcoin is around $7,000 and I sell when it hit up to $11,000 and I didn't expected that It's gonna increase as much as $20,000 supposed to be my shares could be almost 3 times. Well, everything is unpredictable as what happen to the value of bitcoin is volatile as well as other crypto currency here in the cyberworld. I'm just hoping that I'm gonna be lucky enough soon. Cool
