Seed investors almost never sell in series a or series a investors in series b. Company just raises more money and dilutes the previous investor. Investors only get bought out if there is a serious issue or reason to remove an investor, or later stage there is lot of demand for the stock so the company offers a secondary. Investors are not really in the business of making small returns. IPO and public markets are different case where private valuation can turn out to be inflated and tanks after the IPO. However, retirement funds usually cant buy in to IPOs and institutions can often buy the stock before the stock trades publicly so in that case it can be the public who is left holding the bag.
