[Insider: Nasdaq to Strengthen Scrutiny on Companies Holding Cryptocurrencies] Odaily Planet Daily reports, according to insiders, Nasdaq is intensifying its scrutiny of companies listed on its exchange that attempt to boost their stock prices by raising funds to purchase and hoard cryptocurrencies.

Nasdaq, the exchange where the vast majority of cryptocurrency-related stocks are traded, now requires some companies to obtain shareholder approval before issuing new shares to purchase stocks.
