Yes, the selloff reasons are pretty evident:
- new big competition with big plans (so far it's all vaporware though)
- no ETA on new blades
- ASICMINER hashrate doesn't keep up with the quick difficulty rise
- no info about new chip design
well, I think this doesn't tell the whole story. The drop in price times perfectly with the Labcoin bubble. So, people are likely moving into riskier positions to try and make some profit on the hype. As Labcoin drops back down, AM starts coming up, which to me, indicates that those who are profitting on the crowd are putting profits back into safer places to hold.
At the same time, USD/BTC is increasing, so I do think people are locking in some profits, there.
On top of all of that, the rebound from yesterday was erased almost signle-handedly by one trader. The drop in price yesterday also was executed in the same way, with someone filling buy orders from 3.7 to 3.5 almost instantly. So, there is a bit of market manipulation happening here, too (or maybe just ignorant traders).
I would like an update from FC regarding the recent hash decrease. Typically, when we see hash rate moving like this, it means FC is moving things around. They may be testing the lease program, new hardware, etc, but we just don't know.
AM definitely has a lot of hardware/TH on hand, so there must be a reason why the hash rate is not increasing. I'm sure FC and team are working on it (they are not likely sitting around), but it would be nice to know the situation.
