After the stock is listed, investors who hold the original shares cannot sell the shares casually, because there is a lock-up period, and only after this lock-up period can shareholders who hold the original shares sell the shares and cash out.
The price of original shares is very low. After the company goes public, the original stock price will turn many times, which is the fastest way to increase wealth in a straight line. As an old employee of the company, if you have the opportunity to get the original shares, you must try your best to get the most original shares.
