I feel for you since I also played with those securities
Not really on Bitfunder since I never used that exchange Weexchange ate my free ripples so no real loss there
BTCT however was interesting since I did walk away from Labcoin and even Activemining fairly intact and got into Labcoins messed up IPO with my shares cut 1/3rd from the initial amount and sold early on that pump, even declared it publicly to the chargin of some who were arguing 10x the price not 5x was a good exit point lol, then played the speculators roulette after seeing that wave go up and down a few too many times all in all I pretty much started off where I was initially plus a little gain.
Neobee however I did lose a bit in but I sold most of my shares a bit too soon and then the rest on the March 17th News at the 0.003 and some range when it went to 0.006 and was buying a bit back on the drop to its IPO price only to find to my surprise a few days later that in the span of two weeks it went from being a super star to dead in the water, so quite the turn of fate.
Not really sure if it was a scam yet although it did get Mircea banned for swearing at the mod and writing off topic posts lol.
That said AM was the one that caught me ironically since I had an average weight at 2.5 BTC a share which after Gen 2 got delayed pretty much left me with a modest gain instead of a large one. That said unlike the other securities AM pays out honestly and is still a good company even if it dropped down in price so my own fault for speculating to high.
Playing the speculators roulette after an IPO is always a challenge.

With vircurrex my 10 bucks in litecoins are frozen lol but I call that a loss even though the site still runs for now.
Left a small balance in the Blockchain app wallet but learnt that cold storage is safest less the amount you leave in exchanges which are always at risk. Also made an instantwallet account to put faucet funds into but of course it closed operations a week later lol... So that was my 101 into downloading the QT client.
Bitfunder I got lucky since I did not like Weexchange it just was too bloody clunky for my tastes even though Ukyo and other users said it was designed to act as a seperate unit if the exchange went wonky on btct burnside closed his service professionally securities aside although it is worth noting that Labcoin and Activemining were Voted in, so the gamble now is in trusting havelock and for now they seem ok the only real exchange really to survive of the last three, (mpex living through it all but with scarcely a few securities lol) but hopefully I see the signs again if something changes, been fairly lucky overall but it only takes one mistake to lose a fair bit.
