If you hold tens and hundreds of thousands of bitcoins, then this may affect the market. Small amounts practically do not affect it. The cryptocurrency market needs capitalization, the infusion or outflow of large amounts of fiat money in the market is very important for pricing.
Bitcoin holders in large numbers certainly have a lot of money, which if invested in the stock market can affect the shares traded. As is known that the bitcoin market is open 24 hours without holidays, in contrast to stock trading where Saturday and Sunday are not active.
