“Bitcoin Officially Mainstream As Microsoft Adds Excel Currency Option”

This is probably a pretty good indicator that bitcoin is approaching critical mass for awareness, but I think its exchange rate with mainstream currencies like FRNs will continue to be very volatile for the next 5 – 10 years, until it settles, which will be at a point where it reaches an exchange rate that represents its “latent” (true) value corresponding to somewhere between $500k & $1 million per BTC (based on current FRN inflation levels), maybe a little more.
