When people cash out of ETH...they cash out into BTC....if those people who made a killing in ETH wanted to really cash out....then this is bad for Bitcoin, cos they would sell ETH for BTC, and then BTC for USD.
bad or not, it's still a high possibility.
Every bit of news about bitcoin actually seem to have an effect to its value, the hospital computer hacker may even have an effect.. just read the threads in this section and you'll see some that mentions why a sudden move of price.
Also check the popular blogs like coindesk and the rest.
oh come on. 40 btc is too small amount to make a dent on the price. and the news is not exactly good enough to trigger a rise either.
