What Bitcoin Securities / Stock exchanges are around? As a historical user of GLBSE I thought the concept was brilliant. Sadly that did not end well but many more have appeared.

https://btct.co/ appears to be the most popular.

Which other stock exchanges are available and what are their advantages &amp; disadvantages?
*UNFORTUNATELY THIS IS ALL OUTDATED NOW, SORRY*

BTC Trading Corp. - https://btct.co

Pros: good notifications in email, good analysis of your positions

Cons: always in development, weird UI when new features are added, 24 hour withdrawal limits, but you can request larger amounts but it is delayed a few hours as the admin has to move the bitcoins from cold storage

BitFunder - https://bitfunder.com

Pros: looks more advanced than BTC Trading Corp

Cons: stock prices are typically lower there on cross-listed securities, no email notifications when anything happens, lame we-exchange thing

Havelock Investments - https://havelockinvestments.com

Pros/Cons: Best UI UX, Canada.

MPEx - http://mpex.co

Pros/Cons: Run by a multiple personality lunatic. 

Cons: Admission/Listing fees, I forget. Nonexistent UI
