Bitcoin is not decentralized anymore. There are few people manipulating the market which isn't good for small investors. If things are continue to go like this then soon it will be a currency of rich people only and it will affect small investors very badly. Stop selling your coins no matter what.
I'm not sure whales really exist, I think it's just a myth...
we must be able to distinguish what is called a centralized or decentralized coin. Bitcoin since satoshi was created is a decentralized coin, nothing can change that. don't because the price changes because of market conditions then you say Bitcoin is not decentralized anymore. please throw away that mindset.
