I think bitcoin is still overvalued at this point in time. It went up 10 times its value in less than a month, and less than 6 months after the previous bubble peak.
Remember it took 2 years after the $30 bubble peak to bubble again to $266. The price can't rise this quickly without some serious correction.
At this point in time I wouldn't pay more than $300 a coin. I might pay more per coin in the future, but right now $300 seems like a fair price.
You guys are laughing that $30 was a steal in June 2011, but it was $1 in April 2011 and $2 in Nov 2011. $30 was definitely overpriced at that point in time.
