While I believe markets are efficient when it comes to stocks, bonds, currencies and commodities and reflect all known
information at the time, in the case of
bitcoin, and a few other instances like the ONLY stock I've bought in over a year (now up big), when I start to see the mainstream media reporting
on something, google search volume through the roof (chart below) and lastly, when your mom asks about it — it may be signaling mainstream acceptance and
further expansion of a major bubble.
Further specifics
on what to do after a coin - split will be announced
on Bitcoin Magazine (and most likely
on bitcoin.org and other sources of
information) if and when a coin - split occurs and we have a better understanding of the post-fork situation.
