There is no need for EVERYONE to sell at same time. Everyone should have there own strategy based on their DD, risk apetite, etc. All I ask is that if you sell update the spread sheet.
Selling a portion of your shares can aid the stock if the cash is kept on hand to rebuy if it dips... But at some point cashing out means just that. Either way, this is a very explosive time for this company and when a stock is grossly undervalued AND it has sufficient visibility multiple investing strategies work.
