I'll defend ASIC on this one since it gets brought up a lot by the non-researched bears on the AM threads.
If a real competitor appears this might get interesting but besides Klondike heck on a long toss AMC nothing yet.

Nice tracking number

3.5 = Overpriced perhaps only time will tell
I've been hearing people claim this since 0.75
It does control a fair chunk of the network and hashrate is growing + sales of units can't really call BS on that truth

http://bfl.ptz.ro/ (This list is beautiful from a failure view)
Nothing is always cheaper than somethingProfit from placing an order a year ago with BFL: BTC0
Profit from purchasing AM share at IPO: 3.4+.32 = BTC3.72 (ignores huge increase in BTC value)
0 < 3.72
I'll be blunt the price will drop but not to a worthless level the competitors might start moving soon the volumes are the question.
Either way I have seen worse
http://www.youtube.com/watch?v=-eF6FSdur8kFWIW I personally consider a security to be a definite success when (and only when) investors have received back at least the average IPO cost in dividends/final payment. Until then it can only be a likely success that could still end up a failure if the operator ran with the cash - as recovery of funds in scammed/dead BTC securities is pretty much nonexistent.
This is a useless standard for now, because
no honest company will return 100% of its capital to investors within the first few years of operation, and Bitcoin is a few years old. Once we do a few more block halvings this will become more and more of a valid way to select blue chips, perhaps.
I'll call this one out however ASIC IPO buyers got their IPO investment back a long while ago plus share price appreciation if you use 0.75 as the basis not yet but from 0.1 if they sold from 0.75 the ratio would be 4:1 + Divs Currently
To necro
https://bitcointalk.org/index.php?topic=106391.0Should we be more worried about the exchange rate
"Giving over half a million bitcoins to a random idiot has the unpleasant effect of creating a high powered idiot. He can now wreak havoc on the exchange rate, which increases volatility and on the long term hurts everyone involved in bitcoins, because volatility is, much like inflation, an indirect tax on users."
But some investors would be safer using just dice and pressing the investor button

That said using an hourglass to look backwards is cheating especially when GLBSE caused that chaos
Akin to saying accountants look backwards while investors look ahead it may be true but the past leads to the present the future is unknown but that's Finance of one form or another
That said the hourglass has shifted and showed AM to be the gem from the turd collection
