Boris, i think a lot of people ( especially GPU miners ) including me are a bit uncomfortable with the momentary situation in the whole market.
BTC is getting worse and worser and all other coins also. I would say nearly no coin is profitable to mine if you have to pay more than 0.15 / kwh
(0,20uS$ / kwh ) mining with GPU´s. In germany it´s impossible. We have to pay between 0.25 and 0.35 / kwh
Supposing that the next bitcoin bubble begins this summer and that it is similar to the previous two bubbles, then I expect altcoin prices to follow bitcoin upwards after the rally is obvious. In the months between now the rally, high-cost GPU miners will power down and await the rally. Miners are very likely to be postponing hardware purchase with coin as perhaps 5x more mining hardware can be purchased with the same held coin when coin values again dramatically rise.
When the next rally does occur, and maybe at the tail end of the rally in fall 2014, new scrypt ASICs will forever push scrypt coin difficulty out of reach for GPU miners.
I continue to rent my GPU rigs to scrypt miners at low profit, and I am awaiting a more developed scrypt-N rig leasing demand before I switch over.
