You say it is dropping lower and lower but it is still 200% up on itself from a month ago.  After a spike there always has to be a fall. It will probably level out for a bit being worth 0.00004 BTC.  Once bitcoin starts to increase in value again and move above $1000 people will yet again begin to look for a cheaper option to get into, something that is even more volatile in price. Zetacoin is a good coin.  It has a solid community and I am confident it will survive.  We will probably see another spike towards the end of January Just as high if not slightly higher followed a longer lull or stable period.

By the way, these are simply my views, do not sell your house to invest on my views.
