If there is some important CEO saying that bitcoin is a scam or worth nothing it may fall, but will always get up, that's the beauty
CEO of what? From time to time people trying to beat the price by talking that BTC is scam. It is free market and open source code, so everyone who have brain know what that mean.
After this last hard fall to $3000 i'm sure there is no way to repeat this price. The worst what can happen is $3500 - $3600
