The stock traded for a year, guarantee the O/S turned over at least once, so all the zero cost basis turned into a profit for those with the shares originally. The very few shorts likely did OK, looking at the short interest with the price action. None of them got rich, some likely lost a buck or three. Short interest really was 4% for the last few months, last data was less than 3%.
The "few fools" who bought at high prices during the pump and everyone else whose cost basis wasn't zero (the vast majority) were trapped. If that land were to sell for what the company claims it is worth, the stock is worth about 20 cents. PPS ended at $2.90(?).
