Bitcoin is decentralized which means no one person or company can control it.Yes, bitcoin can be manipulated by directly or indirectly for example positive or negative news can trigger panic sell or pump, whales also affect bitcoins price like any other investment options.Every investment options can be manipulated. Bitcoin is just too volatile to predict where prices would go.
Bro, I really feel I have been controlling the market recently. Every time I buy the price goes down and every time I sell it goes really high. It's not China apparently. LOL I have been buying DAO Maker recently because they release a news that they're more open now, which means everyone can join their token sales with or without staking their token. But then the price continuously goes down, but wth, we'll hodl and never sell
You not checking about the market condition after announcement by China exactly with bad news like bitcoin banned and make price dump, I think have several whales and billionaire how they can controlling with bitcoin price when have to dump and pump. I know still have investor keep holding bitcoin assets but they always as panic selling whales make bad news and price dump, after they have got chance bitcoin on lower price next as opportunity how to make good news with bitcoin and price pump drastically few days later and keep repeat this strategies on every time.
