(1) A huge amount of hashing power is now in the hands of companies that can stamp out one set of chips after another. Few seem to make it to retail (i.e. BFL)
(2) Most of the former GPU miners, once a large support base for the coin, have lost interest due to the BFL fiasco and the fact Avalon shipped only a tiny number of retail devices
(3) Concentration of network power in the hands of a few is a disaster. Precisely the opposite of what BTC was supposed to be all about
(4) Raw gh/s figures are irrelevant given that only a tiny number of firms have ASICS designs. THESE COMPANIES NOW EFFECTIVELY CONTROL THE NETWORK
LTC is looking very strong right now. Holding its USD value as BTC falls.
The two may meet in the middle
Proof Of Work is not an effective way to achieve consensus in a p2p network. http://www.links.org/files/decentralised-currencies.pdf
the only thing it achieved is an industry for SHA-256 hashing.
