Nasdaq to step up scrutiny of cryptocurrency firms: Source

According to people familiar with the matter, Nasdaq is increasing its scrutiny of companies listed on its exchange that attempt to boost their stock prices by raising funds to buy and hoard cryptocurrencies. The exchange's move could slow the cryptocurrency boom, which is pushing more and more exotic tokens into the mainstream market. Nasdaq, the exchange where the vast majority of cryptocurrency stocks are traded, currently requires some companies to obtain shareholder approval before issuing new shares to buy stocks.
