According to me central bank of countries have zero to very little impact on the prices of the cryptocurrencies cause cryptos are held by people worldwide and not controlled by some central bank or the government. As long as people hold firm grip on crypto and don’t get manipulated by the government or central bank there are usually no fluctuations in the price of a particular coin or the total market cap.

The speeches are being given by the central banks about cryptos past 3-5 years, but still crypto market has had steady and healthy growth which shows that there is no manipulation by them.
