When will the Bittrex wallet be active again?

Dev, can you tell us what your plans are to get this on the big exchanges with volumes so that people want to invest?

Is there a bounty for pointing out an error in the OSX wallet? It is not a functional error but a cosmetic one yet potentially embarrassing.

Many people have waited for the price to bottom. If they feel this is the bottom they will get back in and buy up.

What will the whales do when they have all the coins? Should a coin not be distributed between many many different people to improve circulation?

I am still in the black with BC and still in but this ride has taught me some very interesting and valuable lessons about the crypto market.

Can OP look into the actual Mac wallet client number? The Mac zip file is called v 1.0.5.1 but the file in the zip file in "About Blackcoin-QT" says 1.0.5.0. Is it the latest version of the wallet in the Mac zip file?

Why the big red letters? We can all read normal font.

Anyone want to buy my Magneticoin?    Wink

Maybe if we new what this coin was about and where it is going to. For some reason the dev is ignoring us.

3 days of long hrs perfect uptrading and taking more coins off the market and mintpal causes me to be set back more than 300 coins by doing everything in their power to slow me down.

GOODBYE MINTPAL!!!

No time for trying fancy things in this market at this time. Best to just sit tight.

MGC  VOTE is www.cryptoaltex.com/index.php?page=newcoin MGC Magneticoin


Instead of asking to vote for the exchanges can you please answer the questions regarding the vision of the coin? People might just think that you are just interested to get on the exchange to dump the pre-mine you kept.

I can not understand why the GPU miners complain, the algo is SHA256 and you knew that.

Yes, difficulty quickly went up out of reach of GPUs.

I really don't understand why wallets have no Two-factor authentications !

So many people would still have their coins.
This should be the number one priority for the dev-team.
What u guys think?

And how will this be done? Who will hold the second key?

It would work as follows:

1.5 factor authentication
Implement a normal Google Authenticator or Authy code into the wallet below your wallet password when you want to do a payment. The Google Authenticator or Authy app exists on your mobile phone. To set it up the wallet needs to display a QR code or manual code during first setup that becomes the secret key between the wallet and your mobile phone. The wallet then just need to calculate the code based on the secret and the algorithm just like it works on the exchanges. The secret key between your wallet QR code and the mobile phone becomes the 2nd key, of which the derivative the changing code is entered into the wallet at payment time. However the secret key also exist in the wallet and therefore could become available to the hacker as well in a similar way than the wallet private key.

2 factor authentication
True 2FA is when the code or response is not entered into the same channel as the password, but is sent via a separate channel (out of band).  For this to work there needs to be a backend server, but since the crypto-currency principle is based on p2p there is no backend server that can match a challenge-response to your wallet payment request. It is however possible to implement true 2FA on the exchanges because currently they all implement just 1.5FA.

You hit the nail on the head.

another shit coin, go away

I don't know why the dev does not reply with the info.

Please VOTE on https://www.mintpal.com/voting already more than 630 votes and if someone can pay have any minor btc is added to accelerate the process in advance thanks to the contributions address MINTPAL BTC 1E3D2hhCPaRhvBKsBjyH62qbD1zDGYtEv2

This is all good, but can you tell us more about your plans? What is your vision for the coin? What work will the pre-mine be used for and how far are you with the work? I am a little bit uneasy that you want to rush to get to Mintpal while you have not given the community anything about the coin's plans or what it is about. So far we only know it is SHA256 algorithm, the specs of the coin and the name.
3797  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] BlackCoin (BC) | on exchanges | PoS | No premine on: April 14, 2014, 11:29:54 AM
The only thing is that unless I understand PoS incorrectly, that your coins have to be in your wallet at the address it was sent to. If you connect the loaded wallet online and leave it there, the network registers your balance and staking starts. While you leave the loaded wallet online then you get Interest yearly compounded daily, meaning that 1/365 of the yearly interest get added to your balance today and tomorrow's 1/365 of the yearly rate gets calculated on today's balance plus the fraction of interest added to your wallet today. If you take your loaded wallet offline and lets say bring it online once a year you still get interest but on that day meaning you lost the interest on interest if you left the loaded wallet online. If you move your coins offline to another address then the staking stops and you get no interest.

The suggested security principles seem work against the principle of PoS or am I wrong? Lets assume everyone becomes security conscious and move their coins offline and leave empty wallets online. How will staking and decentralised processing work in such a case?

Guys........today my 27k bcs have been stolen.

I am shattered completely. It is sad that I can no longer buy any bc now as i have no money left.

Somebody with address B5QC3Fb7D4WGfXXd3EgvJLFEQuwGKDcKVD (bastard) stole my all money.

This is really sad.....I think my wallet has been hacked.

any help

That is really bad Sad

Was your wallet:

1. Encrypted and closed for staking not connected to the Internet
2. Encrypted and closed for staking but connected to the Internet
3. Encrypted but temporarily opened for staking and by definition connected to the Internet
3. Unencrypted and staking and by definition connected to the Internet

Also:
4. Do you have AV installed and if so which one?
5. Do you have a firewall and have you blocked all unknown apps to the Internet
6. OS that your wallet was kept on.
7. Did you have a strong password and please tell us the complexity of the pwd you had for your wallet eg. 8 char, 1 digit etc.
AV was installed but it was connected to computer and pwd was 8 ch with capital and few numbers

Encrypted but temporarily opened for staking and by definition connected to the Internet
firewall was not there
Windows 7

You probably got malware on your PC then.

Until there is some kind of 2FA for making payment from the wallet one should take a wallet off the Internet, make a backup and only go online to make a payment, transfer small amounts to a temp mobile wallet or to collect interest once per year and wiping all traces of app and wallet from your PC after each time. The bane of crypto-currency. If there is money and value the hackers will follow. Challenge to the devs to implement something to protect the open wallets sitting on the Net, or at least a detailed guide for the layman of how to protect his wallet when using PoS.

Once again : don't use a weak OS for managing your money. Ubuntu 14.04 LTS is about to come. I personnaly use Linux for security reasons, and I recommand you to try this :
http://xubuntu.org/

I just back upped my wallet to 6 usb sticks that i am going to store in a locker at a bank.
And I have then deleted all files related to blackcoin on my pc by using eraser. No way I can get hacked now.


Are you not doing staking?
