Do you think that we should prey only on institutional investors to pump the price of Bitcoin?
It's true that big companies aren't affected by FOMO and panic selling,but it's also true that big companies are "under the radar" of the government,therefore a particular action taken by the government(new regulations or something else) could easily force those companies to leave the crypto markets.
Bitcoin(and cryptocurrencies in general) needs the support of the people,in order to grow and survive.
Not sure what you mean with your question. Institutional investors will buy bitcoin whether we like it or not, and it's the same with retail investors. It's not like we can prevent institutional investors from buying just because of governmental risk.
