This is why exchanges with public asset lists are important (for example, BitFunder). Even if BitFunder suddenly shuts down, asset issuers will be able to know who owned what.
If bitfunder "suddenly shuts down" the list is not available because it's on their website. Though there's always this:
https://btct.co/history-bitfunder/ (don't use IE, I don't mirror the superfluous content so it breaks)
The list also does not include any way to contact the shareholders. (Another Edit/Add: Bitfunder did in fact add this option, just found it in my account preferences! I can share my email with the issuers!)
btct.co makes shares/email/bitcoin address lists available to issuers on the site (html), via the api (json), and by emailing all issuers complete lists at 12 hour intervals.
@BitcoinINV: Unless you were planning to list a really crappy security, try sending an email again or go on IRC.
Was not listing nothing was getting info about what they would and would not allow, some legal questions and other things. IRC is empty tried that for 2 days going in there for 15 minutes at a time asking "anyone in here who can tell me about securities requirments."
This is not good enough answer for me lol
https://bitcointalksearch.org/topic/m.1531827Unfortunately most of these places (btct.co included) are one or two man shops. There's not a lot of income to support much more, so when something happens at home, things get backed up. Hopefully he's back soon and things are ok.
Edit/add: Heh, I forgot to mention the times when you're just super-focused on an awesome new feature!
https://bitcointalksearch.org/topic/m.1550069Once you dispense with need for superficial "niceness" and "profesionality" and consider things rationally, you may find out there's a strong reason behind how MPEx does things. Both Bitfunder and BTCT I perceive are doing their utmost to be nice,to cater to everyone...and I fear they'll spread thin and it will be their undoing. Or maybe not I hope, they are nice folks.
Oh and MPEx was reaching 50k/mo volume long before satoshidice, due to their in-house BTCUSD options trader-MPOE. Many ignore MPOE at their detriment.
Edit: MPEx publishes its database,too, in encrypted form. Just releasing a GPG key will be sufficient to decrypt it.
We definitely try hard at BTC-TC. Too hard at times. But we're still an early startup, (~6 months in biz) so that is to be expected. I've had a few discussions with some community members and they've had some great ideas for tightening controls on new listings, so we'll be implementing that soon. We also have some of the strictest controls out there on funds, which I believe were one of the major causes of the GLBSE price crashes right before the operational collapse.
Cheers.
