Whales have no control over it during the bearish market. It's not the whale but the global economic has been pushing people to dump their tokens and exchange it to the cash or fiat money to keep their value from the volatility. You must also aware if there are some crypto companies that already collapse and even venture capital like 3ac was also going bankrupt as well. That proves that if the world is not yet fine for now. The roller coaster may still continue if another bad news will come very soon. prepare yourself.
Whales can manipulate the market but it has nothing to do with the roller coaster events in the crypto market. These are things that are called inevitable since they serve as the outcomes to the positive and negative events not only in the market alone but the whole globally economical. But as the crypto market is full of uncertainties, if today we are witnessing the dump and bloody market, then next to it is a bullish market that is all green and pumping. And bitcoin and ethereum prices will always be seen dominate the market.
