These guys appear to have unlimited funding and will not surrender until a Bull run is in motion!
in case you didn't know bitcoin daily trading volume is 4-5 billion dollars every day these days that price is stable. during bigger moves it can reach a lot higher. and the market is not centralized like how altcoins are. for example Binance has all the volume of altcoin market and the price is mostly set there!
but in bitcoin it is Coinbase, Bitstamp, Bitfinex, Kraken,.... and 10 others each having between 5 and 10 percent of the market and they have no connection with each other.
now for someone to control this market (the way you suggest) they have to be on all these exchanges at once and have at least $1 billion in the market manipulating it!!!
not to mention that if what you say is true then price should have gone up to $10k by now. LOL
in comparison you can pump altcoins with less than $10k and some of them with even $1000
