In light of the recent ASIC attacks on BTC
the difficulty has been shutting out GPU miners making BTC less profitable to mine. In addition a lot of ASIC owners are selling BTC in order to recoup their ASIC hardware investments. This has put a lot of pressure on BTC prices.
However alt coins are still pegging to BTC price. Coinchoose identifies coins based on profitability to BTC. Cryptsy only allows trading of alt coins against BTC (3 versus LTC). The damage ASIC's are doing to BTC is rippling through Alt coin valuations.
I think we are coming close to a significant cross road.
1. We continue to peg to BTC past the GPU profitability break even point. As a result alts are not profitable to mine and most die a slow death.
2. Alts decouple from BTC and are gauged not by their profitability to mining vs. BTC but to valuations against other fiat currencies (USD, EUR, GBY, JPY)
2. will require the implementation of a better exchange than Cryptsy. Cryptsy is great, don't get me wrong but it has its limitation and while it helps reduce the scamming that occurs on forums it does not do enough to get alts decoupled from BTC and trading independently.
