This statement is not true. There are whales worth billions of dollars. What can you do with 10 or 100 thousand or even 1 million compared to whales? Certainly, there is no comparison in the market with the right analysis.

When you bet on futures contracts for the rise of a currency, you must buy the same currency from the spot market. This helps increase the price. The same goes when you bet on a price drop; you should have enough stock of the currency to offer for sale, so that the sell order is greater than the demand, thus lowering the price.
I am surprised by a person who trades in futures contracts with huge amounts without taking these steps.
