Since you're so optimistic about BNB, after selling it for just a few RMB, there were plenty of chances to buy it back later. Why didn’t you? Especially after 94, when it dropped to just a few cents, it was even cheaper... Now you keep regretting it, simply because you see the overall trend of BNB keeps going up (note, BNB also has bull and bear cycles). It’s like after a breakup, seeing the other person doing better and better, but not willing to make the effort to win them back, so you just keep texting, 'I miss you so much.'
