Anyone with holdings in Snap who aren't named Evan Spiegel or Bobby Murphy have only one option: sell the stock and recoup whatever they can. That's what people are doing. Snap's share price will not substantially recover, and there won't be a return from an acquisition until the business completely runs out of money.
