In the casino craze of the 80s and the IT bubble at the turn of the millennium, at least similar quality stuff came to the stock market, e.g., the legendary Notareal Oy, where the entertainment factor was in a completely different league than in the poorly managed Lifa/Pallas Air.
More of these (too) on the stock market, please. The stock market is a ruthless place because all financial information of a company there is public, and in an IPO, you have to disclose everything possible. Scams quickly come to light, unlike in funding rounds for unlisted companies.
