I know it is basically impossible but what if, while you slept the bull run commenced and the price of Bitcoin climbs to $50k and then goes back to $3k just as you wake up. Then you see the charts for confirmation of what went down while you slumbered. What will you do by then? I want to hear your thoughts on this. 
It is definitely a very bad thing. I used to invest in a token called WPP. I have rated it quite low and only sold for $ 0.012. after i took a nap, its price peaked at $ 0.02 and i sold all my tokens at the bottom price. It is definitely a very bad feeling. Because I am newbie and still have a lot of shortcomings, this is considered the biggest lesson for me.
