And see the game how they played it 4 hours ago. They invested in knc worth 65+ btc, so they added value to knc, but it appears that they have already sold 52+ btc worth of knc after 4 hours. They are pumping and dumping the market price.
That is not all of the pumpers' money that shows in this stats though. Basically the actual pumpers buy the shitcoin before the pump begins then they call up the idiots to buy the expensive shitcoin and as they start buying some others (with bots, etc.) notice and start buying on the rise. Then the pumpers start dumping as the idiots continue buying the expensive shitcoin.
It is also obvious from the difference between the volumes (65 in, 52 out) that shows the bag holders who held on to the shitcoin hoping it goes up and gives them profit.
Then they dump it again by selling their portfolio. You will panic and sell at a loss. They will again buy and play their usual game.
Technically what you explained is just a correction during the pump not necessarily the pumpers. After each sudden jump in price of anything, there is always a dump when traders pull out their profit after reaching a certain %.
Remember the second group I said join in as they see the pump starting? This kind of "correction" is usually them selling to get their quick profit out.
I hope now you understand before investing or trading how much research you should have done and don't take an entry on a sudden pump and dump moment.
It is a high risk method of making quick profit from market manipulation. You see a rocket, you jump on but you jump off quickly too before the rocket crashes!
