This message is an offer of friendship from Elmer FUD, the one “who hides in dark places”. Market traders, and many investors who rely on perceived price dips or price spikes to help them with timing, need to be in a situation where Certainty, Fearlessness, and Freedom from Doubt are present only occasionally. Otherwise, their opportunities to trade would dry up, they would leave the market, and the market itself would become much less liquid. Hence, those of us who have “deliberately opened accounts in order to spread FUD” (according to certain interpreters of unstated intentions) might not be such bad people. For me, for example, “thanks loads to China's spreading FUD recently for giving me he chance to get into Bitcoin near $3,000!” (Yes, I am just pulling your legs. Okay?)
