20 Million Dollars of BTC pumped into a vapourcoin. I lost the price of a night at the pub on UseD... but this is priceless.

Dangerous for whom?

At the end of the day it's up to the exchanges to moderate their business if they want to survive. Small investors are being driven away from alts by the rapacious greed of a minority (which is why fiat is so heavily regulated). So volumes are shrinking, profits are falling... and the big cats are being left to devour each other. I know that I can't afford to buy Any altcoin because it's value can be wiped out in an instant. The alternative is to play the same game and dump on a regular basis to mitigate losses and preserve profits. And if everybody does that the whole system will fall apart.

At the moment there is No safe coin to hold long term. Lite Dark Crypt Cloak and dozens of others have amply demonstrated the fact this week. BTC is no safe haven, but the sheer volume makes it a fairly secure long term investment for disposable income. The rest are as secure as the next organised dump.

Something along the lines of triggering alerts for unusual deposits/withdrawals... placing limits on trades so that a wallet holding more than the entire 24hr volume can't nuke the entire platform... freezing the accounts of rogue traders...

I'm sure there's plenty of other safeguards available..

and it can all be automated.

But the BTC remained in a Bittrex account until they were withdrawn (if they have indeed been withdrawn). And Somebody has to make a withdrawal request, and then confirm it by email. Bittrex may not know the identity, but the surely knew which account was responsible for a 20 megaton dump... after they'd agreed to burn the surplus coin. And they had (or have) to agree the release of the spoils.

I'm sure that all those BTC can be traced back to the receiver. And as it's in the blockchain, it might be a start to look there.

Anybody noticed a massive withdrawal from Bittrex this afternoon?

So these weren't the 'supposedly destroyed' surplus coins being dumped on Bittrex? Where were they dumped then? Because the price dropped from 3K to 150 in a couple of minutes as 1.5 million coins were sold. Too fast for most traders to notice what was happening. They weren't listed but somebody must know where they came from... and where the BTC went. And it might not have broken any rules, but it left behind a lot of very cross victims.

UseCoin to UseDcoin in less than 24hrs.

Not bad. This is truly the age of the pre-dumped coin. I guess Bittrex had no qualms about releasing the BTC. And the rest of us can go hang. So I dumped the rest of my alt holdings and pulled out. Got burned with syscoin as well (the one with the dysfunctional wallets). Moolah held on to the IPO so the devs are having to bodge up something that works. But I've had it with alts for now. Perhaps there's good reason for regulation and fiat.

Maybe it's time for a forum thread devoted exclusively to scamcoins, their developers, and their supporters... with bounties for whistleblowers (held in escrow of course).

Already dumped (at a loss), thanks for the advice... although I did wait for the new wallet, which was pretty underwhelming. And no, I'm not crying about it. C'est La Guerre.
But as a parting shot I'll offer a little advice to those with (windows) wallet issues. It won't solve them entirely (because it still falls over and corrupts the local blockchain), but it should sync.

Avoid The Installer.

This applies to a lot of coins after an upgrade. The installer leaves a ton of unnecessary shit in the registry, and you need to clean this out before installing a new version.

So, save your wallet in a secure place.
Run the installer, but DON'T run the wallet (qt) executable.
Have REVO Uninstaller, or a good alternative on your machine.

Copy the Upgraded QT (program) and DATA folders to a pen drive and remove it.
Run Revo at full strength to remove Every Trace of the coin from your machine.
Replace the program and data folders in their appropriate locations (you can choose these for yourself if you don't want to use the defaults).
Do Not Copy your wallet to the data folder.
Run the QT (it will create a new wallet).
Leave it to sync and download the blockchain.
Once you are happy that it's all in order, you can copy your working wallet to the data folder.

Alternatively use a clean system.
Make an image of the system drive "C:" using Acronis or one of the many excellent free imaging apps.
Install the wallet and make the copies as above.
Shut down your system and replace it with the clean image.
Fire Up and Restore the copied system and data folders to their appropriate locations. Proceed as advised above.

Alternative 2 is a method I use regularly to ensure a clean and virus-free environment. It's not as daunting as it seems if you include trusted software in the image, and employ a decent strategy to perform upgrades on a clean copy and then upgrade the image. I usually start with a backup of my current system (for a quick restore in case of problems), replace it with the most recent image, upgrade my software, drivers etc. and then make a new image before starting to use the upgraded system.
But i digress...

Goodbye and good luck. Encourage someone tech savvy to try my methods and report back with more detailed procedures.

Lots of iMpatient whiny people, such as myself, have used dozens of coins without encountering such a mess from Day One. Perhaps the crash had a little to do with the underlying technology based on an Outdated Version of Litecoin QT. It evidently wasn't designed to run the bolt-on accessories borrowed from NXT. And by all accounts they still don't run effectively. I gave up trying to run the new improved version, which crashed every time I closed it down. Doubtless it'll all be up and running once the coin's on a par with Doge. Then it's 'to the moon' via the Center of the Earth.

Still, it's my own fault for being greedy and wanting to make a profit.

Mintpal should be able to confirm the times from their logs.

Just as a matter of interest can anyone recall how much time elapsed between the start of trade on Mintpal and the notice that deposits/withdrawals were suspended due to issues with the wallets?
Because that's the only period for which it can be claimed that this was a functional coin.

Perhaps it could be repackaged and relaunched as the NorwegianBlueCoin.

Take an outdated litecoin wallet, bolt on some Nxt-alike 'features' without the bother of developing a new codebase, and collect a blockbuster box-office for the privilege of watching it all go tits-up. Another week and it'll be going to the moon on a par with Doge.

Well at least there's been some progress... we've moved from the pre-mined coin to the world's first pre-dumped coin

I've been watching Cryptsy and Mintpal very closely this last couple of weeks and I've noticed that the price drops seem to be orchestrated by huge sell orders (several or tens of BTC worth of DRK) which have no prospect of being filled. In fact the volume of sales is pretty modest in comparison with the size of the orders... which don't seem to reduce at all.
So who's in control of all this Darkcoin? And why do they feel that it's in their interests to devalue their own investments?
Could they be looking for more cheap coin to fund Masternodes?
The problem comes when they undermine confidence so much that nobody else wants to invest. It may eventually offer a valuable service, but that service is by no means unique; and if the big players are continually manipulating the market for their own gain, then the casual user will be looking elsewhere.

Can anyone here please help me out with a stuck transaction. I sent it an hour ago and it still has 0 of 6 confirmations.
X11Coin version v0.9.1.10x11-coin-1.0

The amount sent has been removed from the wallet balance... but I have a backup copy of the wallet which still displays the original balance as available.

Buy Low
Sell High
and... Cash Out.

I took my eye off the ball and lost 18% of my trading assets. It shan't happen again. DarkCoin is not fit to be an investment vehicle... and it won't so long as the developers keep using it as an experimental platform.

For what it's worth, a lot of the blame for the CF lies with the organisers for launching this latest initiative without adequate preparation or issuing Clear Guidelines.
Three Different Versions of the Windows Wallet are available from the website with no indication as to which version should have been deployed for the hardfork.
*** PLEASE UPDATE TO 0.4.8 OR 10.8.8
Stable (v0.9.4.
(last known version 0.9.4.11)
Release Candidates (v0.10.8.
BUSINESSES

Plus the various apple and linux options... but No Overall Coordination... even with the major pools and exchanges.
Even the announcement at the start of this thread failed to give clear instruction on which version should be operating.
Perhaps the children should stop messing with the toys and call in some adults to help clean up the mess.

No. I'm out of mining now, and I've no intention of throwing good money after greedseeds. The problem with mining is it's power hungry for no good purpose. You still have difficulty with POS so the money supply is controlled. But it's a more efficient means of production, rewarding the community rather than the manufacturers. And that's where it started before the arms race began. All that energy and it's not even productive. It's just pumping up the price and earning fortunes for the big players. You don't need power hungry rigs to keep the network alive, or support the blockchain.

Who's mining now? I thought I just hadn't got it set up right but the problem seems widespread of the forums. For the moment the only way to get a modest return (not an unreasonable ambition) seems to be the exchanges. I'm not 'investing' in greedseeds, so I'm out of mining now, apart from POS. Then the biggest temptation is robbing the piggy bank to play the markets.

What's needed is a true second generation coin that abandons the QT and all the archaic Bitcoin standards. The blockchain's bloated, the wallet belongs to the 1970s, and there's no convenient way of spending. You can't even run multiple wallets off one copy of the blockchain without swapping out. But it was never intended to go global in that form. The developers are just more concerned with huge profits than R&D. In the end the whole e-currency market could fail through lack of simple accessibility. Doge is a classic example of huge potential with nowhere to go. Now it's lying in state... and the wheel's getting reinvented almost on a daily basis.
