newbie question: if i want to buy some shares i see both bitfunder and btctco got them, any ups and down to buying on either? or anywhere else?
what happens if one of the exchanges pull a quick one and disappear, do i still have the stocks linked to my btc address or email?
sorry if this has been answered already.
Ignoring all the noise, I will give you my best take on your question.
Currently you have two ways to get REAL ASICMINER shares.
1) Buy them OTC (Over the counter) in IRC or on the bitcointalk discussion forums. If you aren't familiar with WOT (Web of trust) and what not, this perhaps has real risk, as if you send funds to an unknown party and they abscond with them you have no recourse. The benefits are you don't have to worry about one of the exchanges running into issues. (Bearing in mind that if you share your contact info with the passthrough issuer, there are likely remediations if the exchange runs into difficulty.)
2) Buying through one of the two passthroughs. (I assume you by know what a PT is). These were created to provide the benefits of trading on an exchange, since the actual shares can not be. (Automatic order execution, small orders allowed, options writing, not having to deal with individuals that may or may not be trying to rip you off, etc.) Both passthroughs allow you to buy PT shares, and exchange them for real shares at no cost. (Bitfunder traded G-ASICMINER-PT (DeaDTerra) requires a minimum of 250 shares to transfer out, but btct.co traded ASICMINER-PT (burnside) only requires a minimum transaction of 50 shares, which pretty much matches the minimum OTC trades you will find. (People discourage smaller quantity OTC trades so as not to harass Friedcat with too many trivial requests.)
Personally I have traded both via passthroughs and OTC. I prefer using an exchange, so do most of my trading on BOTH of the exchanges (using both passthroughs). They are both solid. Considering that seemingly overnight almost 15% (and growing) of all outstanding ASICMINER shares have made their way onto the passthroughs, I'd say that many other shareholders agree that the convenience of keeping shares in an exchange outweighs the perceived risks. (Remember there are also risks of buying directly from people in IRC and on bitcointalk.)
Since these exchanges trade multiple securities, and not just ASICMINER, I am a bit more comfortable dealing with them. As always, use secure (long) passwords and 2fa (2-factor authentication) where you can.

P.S. - If you decide to go with one of the two passthroughs, feel free to PM me, and I can share the differences I have discovered.
