And re: reading this board to find out if bitcoin is worth investing in: that's what I did, and now I'm holding some of them and so is my old man. Maybe I was wrong all along though, it would perhaps have been better to look at the tone of people posting instead of analyzing the numbers?
Reading a pro-Bitcoin website to decide whether to 'invest' in Bitcoin sounds like confirmation bias to me

i've been here a few weeks, and with /r/bitcoin on reddit for some time.. and it IS confirmation bias. some of the people here are wearing glasses with the
BTC sign on them. but still, this site is still useful for good information - you just have to filter the bad stuff out.
