I think even there's a whales out there they can't break the bull market but I believe whales will start to sell when the price reach 10k value.
The big trade volume comes from fcoin.com exchange according to coingecko and big volume from bithumb. So if there's a whales someone will buy because there are many traders waiting for low price at the bull market season.
Oh then if whales Will sale theirs btc then they will dump btc surely.
That's how good whales manipulates the market, they can create surge and make the rise but same thing, they also can dumped completely and shake
the market, with this current sign of positive movements means that certain whales are working to lift this industry up.
