Big whales are always the ones that dictates what the prices should be.
We can't do anything to stop them since they hold more than 70% from the total supply. If they sell a little bit from what they have at low price then all others will follow, the same thing if they hold then there will be not enough sypply circulating in the market and thus the price will rise.
If you want to make success in the cryptocurrency market you should copy their strategies.
It’s not 70%, it’s more like 60%. Supposedly, only 21 million bitcoins are in existence (however invisible, digital and intangible that may be). It is said that a thousand early buyers of the digital coin own fully 40% of the world’s supply. (And I bet ya dozens of these bitcoin billionaires are drug smugglers, given that’s how bitcoin got its start.) You are betting on the honesty and integrity of drug dealers when you buy bitcoin as a long term investment.
Bitcoin investment contracts and ETFs are managed by professional Wall Street investment firms. They do nothing for bitcoin because they don’t buy and sell bitcoin. While they hold a quantity of bitcoin, that bitcoin never moves. They trade in futures, just like oranges or pork bellies. They don’t trade in orange futures by handing a bag of oranges back and forth on the trading floor! Be careful trusting and following what these investors do. They are out to make a fat stack of cash just like Bernie Madoff was. If one of them gets caught doing something unscrupulous bitcoins price will crash to zero pretty quick. Insider trading is illegal (just ask Coinbase), it’s easy to get caught and it’s very tempting. Be careful!
