Which bad decision?
Sell instead of mining? You already know that self mining is worse.
Sell price is too high? I don't think that's reasonable from an investors perspective. Even for the miner, who knew the difficulty will increase so fast then?
Failure in Gen2 chips? That's not a decision. It's an unfortunate result, but certainly not because he decided not to design Gen 2 at all.
Collect money for Gen 3? Without this, I believe the stock price will go to 0.
I personally lose more than 30BTC on AM, but I think it is my own fault in bad evaluation. Friedcat already returned more than 500% to IPO investors, I don't think he is responsible in pleasing us, who bought atoverpriced shares. The money we lost went to the sellers, not AM.
The main mistake is not maintaining the lead while you have it. It's a fatal mistake.
^^ This right here sums it up. AM was the only delivering vendor who consistently put hardware in the hands of miners for a long while. They basically bridged the gap between the early Avalons and the trickle of BFL shipments that started and other vendors like BitFury, custom-BitFury, KNC, etc. They played a very important role during that timeframe of keeping folks excited about mining while they waited for pre-orders from every corner of the world.
It is actually very surprising to watch the AM fall from grace. All the right factors were in place - close to cheap manufacturing, decently cheap power options, an apparent brain trust who was capable of designing hardware, etc... How they fell
so far behind is my biggest question. It was obvious the USB and Blade market was drying up fast a while back, now people are ticked about share prices (again their own fault), have lost faith in FC/AM due to lack of any substantial info in regards to "what comes next" in a mining market that is somewhat toxic to enter right now, and to be perfectly honest there are other options out there for people to risk money on. I hope for an AM renaissance as well, but I'm not keeping all my eggs in this basket.
While AM may have a plan in place to shake the market back up (or at least re-enter in a meaningful way), confidence is huge and people are lacking confidence in AM. It's perfectly okay to fall behind if you're secretly working on a bomb you can drop once all the other vendors have become complacent, but that bomb might be too late when you can't find any hardware that is on the nice side of the "worth the money" investment.
