Tonight, the micro-strategy sector of the US stock market has collectively collapsed. The main reason is that Nasdaq is going to strengthen its scrutiny of listed companies investing in cryptocurrencies, simply put: regulation is coming. According to disclosures, Nasdaq requires some companies to obtain shareholder approval before issuing new shares to purchase tokens, and they must disclose this to the market in a timely manner. If they do not comply with the regulations, they will face delisting and trading suspension. For some micro-strategy companies, it might be okay, as the tokens they hold and their buying behavior can be seen on the blockchain, but for most altcoin micro-strategies or small companies, the micro-strategy dividend may be over.
