It's a lot. Market cap doesn't matter. It's about liquidity on the exchange. And people actively trading. Normal people won't day trade so they have no control over the price despite what the market cap is. The only thing that would matter is holding a majority monetary position while trading on the exchange. Then you can dictate price movement up or down. And it doesn't even have to be a big exchange, they're all connected to a certain extent to prevent arbitrage, not to mention they all trade the same way via algorithm. But even then it doesn't matter as they trade in millions and millions of fractional shares to bring the price up or down. The only price that matters is the last sale price. The crypto you are buying is from them. The crypto you are selling is bought from them. They move the price to do the opposite of what you do so that it's always buy low sell high. Always. It's the same panic algorithm that trades stocks. They want everyone to paper hands or diamond hands depending on where they can make the most money. Normal people will always be left holding the bag.
