Yup, fund managers and billionaires can control and i believe exchange site / owners / CEO? that promote their own coins, like Binance BnB / QLC / WPR?
they can pump these coins anytime they like. so its is more like of a timing i guess if a person is a day trader.
im not good in trading
just sharing some of my thoughts.
Im quoting my statement, and based on my experience in Binance the best word to me is not "CONTROL" its "INFLUENCE"
Billionaires and Whales can influence BTC price, for example, if AMAZON adopt BTC, BTC would spike, REASON: Biggest Online merchant available currently same as Alibaba.
(vice versa, if AMAZON and ALIBABA Accept ETHEREUM or created their own Tokens, BTC would plunge and people around the world would be attracted.)
Again, BTC was created for PEER-to-PEER Trustless transaction, meaning the community can influence these Billionaires as well, remember that Dimon apologizes to BTC when he called it a "FRAUD" because the community stand tall, and without the community their will be no consumer, no AMAZON, no ALIBABA and no JPM too..
back to Binance, in Market Exchange we call "Whale" could influence the prices, for example, current price of BTC is 1USD, and everyone would like to buy BTC but the WHALE created a "WALL" a WALL price of 2USD, it is either the community buy the coin to drag the WALL down so everyone can hold on to the coin and influence future market..
in reverse, Community could also fight back by reselling the BTC into higher price against we so called "WHALES"; BTC Community could create a bigger wall for Billionaires..
The thing here is, as a community, we are not organize or centralize, when a FUD come into the game, WEAK hands sell their coins, giving back what i call "INFLUENCE" to the Billionaires.
This is what Cycle of crypto for me and "Controlling or Influencing BTC value"
best of luck.. weak hands and fomo are the reason why these Billionaires have the most BTC...
