Well, probably the most news worthy is reddit, but you can google search and find numerous amounts of btc news sites.
Coindesk is another good one but it all depends on what exactly you're looking for.
Reddit and this forum. I got burned couple times by some news.
Checking more and asking people here was the best in the end. I
asked the same question, where to find valid news but I only got
classic answers, people pasted links to news sites we all know,
nothing new is there.
Reddit, forum like this place have a lot of people who actually do
something and do deeper research then the rest of us, thanks them
for that, these people provide better and more valid info then any
news site I know.
