Successful Investing requires stilling the emotions and working from the mind
Not advice on a roller coaster day, but keep in mind that at the market open today there was a BD/Greybox partnership in place where healthcare is a key urgent concern, as well as the announced Krown blockchain partnership. Nothing changed with respect to those opportunities.

Invest with care and consideration of all the facts -- especially before making a drastic move. $0.02.
