Something that people need to understand is that if whales accumulate a coin, it's not a good thing. We are seeing this in recent days with $BTC $ETH , etc.

For example, if I had 500 BTC on the exchange, I place a short order and sell 250 BTC little by little, small investors will get scared and start to sell. Not only will I be making a lot of money with short futures, but later I will also be able to start buying the BTC much cheaper while placing a long order.

The whales are the enemy. Wherever they go, they destroy everything and take all our money. What's the secret? HODL. Don't sell, because that's what they want.
