As these exchange sites are dropping BTC, all our altcoins are going dead. This is not fair. This is cheating.
lol this is what happens if you start trading bitcoins without studying its eco-system.This is just the start,I want to see these kids freak out considering the amount of faith they put in these exchanges and the bitcoin rates.If you think of that prices are determined by exchanges and coins are actually sold by exchanges, you're right 
We all determine the price, exchanges have no effect on it.
They do! They can heavily manipulate the prices! You can easily check that yourself.Go on an international exchange to check the price of a coin and compare it with your local exchange,you will see the difference. We all determine the price, exchanges have no effect on it.
