We all have advised these much days others not to store bitcoins in exchanges as they might get hacked.
But is this the only issue we are facing or do we all contribute to price manipulation by storing our bitcoins in exchanges.
So in order to avoid exchanges from using our bitcoins and manipulating price,we should immediately transfer our bitcoins to our wallets.
Unless we are going to trade immediately our bitcoins,we should not store our bitcoins there.
Where you hold your coins makes no difference when it comes to the volatility or the manipulation of the price, the reason this is recommended is because exchanges are the target of hackers and if they find a way to penetrate the security system of the exchange then the coins of thousands of persons are at risk, something that is not true if you are the one holding your coins in your own wallet that you control.
Also I will not worry too much about what you're doing to contribute to the volatility of the market because no matter what you do or you don't do you are a participant of it, for example people blame traders for the ups and downs of the market, but people also blame the whales that hold their coins because that makes the market more unstable.
