Since most of the major altcoins move up or down at the same time as bitcoin, aren't they all controlled? How does it work?
There’s a rumor about this but I think whales can’t totally control the market, though they can influence it but its already a different approach. If you think Bitcoin price is manipulated, then try to know when to buy so you will not get trap if ever. Altcoins still follow the trend of Bitcoin because it is still the top coins that fully influence the market, any fud and news can make Bitcoin price move.
