2  Alternate cryptocurrencies / Altcoin Discussion / Re: is ChainX a scam?? on: July 15, 2020, 06:53:36 AM
They are not a scam exchange, people are still using it and can still withdraw money normally. But this exchange is not suitable for you to join IEO because most of the IEOs there have failed and do not have any successful projects and helped investors to get profits when investing.

I was wondering if you could answer this:

- Chainx.org vs chainx.kr are they different websites? different projects?
- One seems to be a korean project another chinese?
- ChainX.org is a project collaborating with polkadot, and not an exchange, they have a dex in app
- Chainx.kr doesnt have PCX (polkadot parachain X) listed which is ChainX.org's currency

So are these the same project? that was my main question

Not the same project at all,
Lots of newbies fudding PCX cause they think it is chainx.kr shitty exchange
just spend some time on chainx.org website and read the white paper. It connects other blockchains and assets to Polkadot chain.  
For me, its an impressive project, main net is live and PCX is a steal right now at $1.80, I am staking it for daily interest of 0.125%, compounding the interest by re-staking the daily interest every 24 hours. After 1 year the compounded interest will be in exess of 60% of the initial stake.
It has 82.5% of 5.9M Current supply being staked. Total supply is 21M
PCX still has a MC under $12M

Targetcoin,

So far you have sold 406,000,000 coins in ICO
Your target is 1.34 Billion coin sales in ICO.

What will happen to the unsold coins? Will they be burned? If not why? Why has this crucial information not been published anywhere?

Have any of your team ever been "Professional traders" at brokerages/Investment Banks or is your team comprised of "Retail traders?"

cheers,

the dev doesnt care what the community voted he has made his mind on the 10k for masternode

Link?
5  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN ][SCORE] Masternodes will Delay! Cant say how long on: August 11, 2017, 05:36:31 AM
I think 150K is unrealistic even at today's prices; that's 0.1875 BTC you're asking people to invest in a coin with no certain path or future and ranked 462 on the marketcap its just not gonna happen imo. Most people don't have $600 worth of BTC to blow on a random altcoin at the bottom of the marketcap. 25K is understandable and maybe even 50K if you really want people to work for a mn(I personally don't, I believe they should be available at a fair price to everyone that wants to invest in one).

Striker,
I get where you are coming from however, the 150K figure was decided by the community right here by poll. The Dev agreed to it and that was the target anyone interested in running a MN has been working towards. If the dev now reduces the number of coins required by any factor. Some may think he used the 150K figure to sell the coin and increase its liquidity. Either way, going back on his word and the original wishes of the community is a bitter pill to swallow.

If people dont have $600 worth of BTC to "blow on a random altcoin at the bottom of the market cap" then perhaps they should move on, a MN in this coin maybe isn't for them. 0.1875 BTC is not a lot for 150K coins when a coin is less than 6 months old. Remember back in 2013 when 20,000 Potcoins were selling right here for 1 BTC? If that were any benchmark then one might say 100K was more of a realistic number. Given the reduced number of coins in circulation and minimal pre-mine, 150K is fair compared to the example above.

If he is going to go back on his word, then perhaps a fair solution would be to add a POS feature and do away with the MN idea all together.

Dev.
Better make as you said before. Score 150k and 75k Trade. You said Masternodes long delay. So people who really want Masternodes. Will time or buy coins or mine them while the difficulty and the price is small.


what he said.
stick to the plan, 150K per MN.

You go changing the goalposts now and its going to become a SCAM.
7  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN ][SCORE] Masternodes will Delay! Cant say how long on: August 10, 2017, 02:46:58 AM
What is going on with this project?
It was decided by the community that 150K coins should be the target holding for MN.
Why the change of plan?

coin needs serious promotion, plain and simple, lowering the price of MN is not going to pull this coin out of the shit.
8  Alternate cryptocurrencies / Altcoin Discussion / Potcoin wallet issue on: June 28, 2017, 09:36:12 AM
I have a wallet.dat file from an old Potcoin QT Core wallet (2014) that contained 20,000 Potcoins. It was the old style QT with the fuzzy pot leaf icon.
The laptop running the client crashed and burned long ago so I wasn't sure of the address and private keys for the wallet, having only ever received the 20 K coins and not ever made any other transactions.
I just finished downloading the latest Potcoin QT Core wallet and it is fully synced to the network. If I cut and paste the old wallet.dat file into the new Client folder in %APPDATA% the balance still shows as Zero. I pressed the receive coins button to get the address from the original wallet and have noted that down (I am assuming at least I did that bit correct).
i contacted the Potcoin support several times and surprise, surprise, not a dickybird ....
Anyone know If its possible to salvage anything from this mess?
What makes things worse is I have watched the value of Potcoin/BTC fall 25% in the time it took to sync the new wallet   Sad
I know this is the Bitcoin Tech support forum but I couldnt find a Tech support forum in Altcoins.
any help much appreciated,

cheers,

OK Success,
I loaded the 218 keys and swept them, the transaction window says there were 4 individual transactions totaling 2504.52489 mBTC. So the default transaction fees amounted to 0.00225 BTC, which is nice   Smiley


Thanks for all of the input,
kev.
10  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Wallet v0.8.6 beta on: June 25, 2017, 10:25:27 AM
Thanks very much for that input.
I do not have an in depth knowledge of the intricacies of the QT wallet so I am confused to say the least.
When I used pywallet to dumpprivkey contents to wallet.txt, it gave about 200 addresses and keys. I only ever used the single address for transactions so perhaps some of those addresses listed are "change addresses" as previously pointed out by achow.
Now that I have the keys, I want to sweep them into my Electrum wallet so if I use Blockchain.info and identify all the change addresses from my transactions, I can cut and paste the privkeys from the wallet.txt file into Electrum for sweeping along with the key for what I consider as my main wallet address. I'll give it a go and see what happens     Smiley

11  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Wallet v0.8.6 beta on: June 25, 2017, 08:20:50 AM
Yes, pywallet dumped the data and there were 200+ addresses each with a list of keys including a "sec" key so I am assuming that is the privkey for each address as each one starts with the suffix you mentioned.

I found my wallet address in among the data along with the "change" address you identified, so it looks like it worked   Smiley

So all of those change addresses which are shown on Blockchain.info are in the wallet.txt too?
I am a little confused because I have been through all of the outgoings and incomings recorded in my wallet and the final balance comes to 2.50677 BTC and this is what it shows as confirmed balance. Yet BCI says balance is Zero.

It would appear that that address is empty anyway (and has been since Jan 2014): https://blockchain.info/address/13oxYTF1CDzz63FV6FDMT7xuzpH8TRnYgb

Perhaps your coins are contained in other addresses? You might want to start checking all the addresses that pywallet dumped on a block explorer and see if you can find the one(s) that has your 2.5 BTC

Another option could be to backup the wallet file... and then update the bitcoin client? Not necessarily to the very latest, but at least something after 0.8.6 and see if it is more stable.



Very strange....
The last transaction on your link is a send to:   1EExPs6ykuk7hfHbQZfpdf39cqMuC5LuWL  @ 4.4999 BTC on 23rd Jan 2014.
There is no record of this in my wallet transactions:



I have been through every transaction listed in my wallet and the balance shown is correct, yet it does not tally with your link. The 4.4999 BTC transaction above is worrying??

cheers,
kev
13  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Wallet v0.8.6 beta on: June 25, 2017, 06:03:47 AM
Thanks for that,
The last transaction from this wallet was on 12th February 2014 where I sent 1 BTC.
I noticed whilst the wallet was syncing it got to 116 weeks to go and the confirmed balance was still 2.5 odd BTC. The coins are unlikely to be stored under another address as I only ever used the single address in this particular wallet.
It has been dormant on a disused laptop since it was last used, offline with full encryption.
I am checking through all the transaction list now.

As soon as I enter walletpassphrase <password> 600 the client crashes saying it has requested runtime to terminate in an unusual manner.

when I enter dumpprivkey <wallet address> it returns:

20:50:46

dumpprivkey 13oxYTF1CDzz63FV6FDMT7xuzpH8TRnYgb


20:50:48

Private key for address 13oxYTF1CDzz63FV6FDMT7xuzpH8TRnYgb is not known (code -4)
                                                                                            ?
Passphrase is correct as shown from the text dump using pywallet   Sad

Just tried the "dumprivpkey" in the wallet again and it gave:


18:32:06

dumpprivkey 13oxYTF1CDzz63FV6FDMT7xuzpH8TRnYgb passphrase <passphrase>


18:32:09

dumpprivkey <bitcoinaddress>
Reveals the private key corresponding to <bitcoinaddress>. (code -1)


18:33:05

dumpprivkey 13oxYTF1CDzz63FV6FDMT7xuzpH8TRnYgb

Thanks very much,
I tried all of that, put the following in the Pywallet.py command

 C:\pywallet-master> pywallet.py --dumpwallet actual wallet address > wallet.txt --passphrase actual passphrase  
and I got the following:

WARNING:root:pycrypto or libssl not found, decryption may be slow.

Now there is now a wallet.txt file in the pywallet folder contains:

'ecdsa' package is not installed, pywallet won't be able to sign/verify messages
Wallet data not recognized: {'__type__': 'orderposnext', '__value__': '\x93\x00\x00\x00\x00\x00\x00\x00', '__key__': '\x0corderposnext'}
The wallet is encrypted and the passphrase is correct
{
    "bestblock": "numerical code here",     
    "ckey": [],
    "defaultkey": "13oxYTF1CDzz63FV6FDMT7xuzpH8TRnYgb",
    "keys": [

There are a list of addresses (none of which I have ever used) and associated "encrypted-privkey", "hexsec" , "pubkey" , "sec" , "secret" data
Not sure if it has dumped the privkey for 13oxYTF1CDzz63FV6FDMT7xuzpH8TRnYgb ??

Perhaps itr might be better if I uninstall everything I have done so far and start over,
I have other wallet.dat files which I need to get keys from so this route would be the best option
This is a guide you published in Dec 2015, please can you review it and add any changes?


Go to https://github.com/jackjack-jj/pywallet and download the zip file. Extract the stuff to another folder.

Then go to https://www.python.org/downloads/ and download python 2.7.11. Run the installer and it will install python. Make sure that when you get to the "Customize features" screen you scroll down and click the dropdown next to "Add python.exe to path" Select "Will be installed on local hard drive" then you can continue.

Then go to https://pypi.python.org/pypi/zope.interface/4.1.3#downloads and select the correct file. The file you want will be either zope.interface-4.1.3-py2.7-win32.egg or zope.interface-4.1.3-py2.7-win-amd64.egg depending on if your windows version is 32 bit (the first file) or 64 bit (second file).

Then download https://bootstrap.pypa.io/ez_setup.py. If that link brings you to a page of text, right click and select "save as"

Go to the folder where you saved the ez_setup file and make sure that nothing is selected. Then do Shift + Right Click and in the menu that pops up select "Open command window here". In the window that pops up, type
Code:

ez_setup.py


After that runs, close that window and go to the folder where you installed python. Then go to the scripts folder within that. Copy the zope interface file you downloaded to that folder. Then open the command window again. This time type
Code:

easy_install.exe <zope filename>

where <zope filename> is the name of the file you copied.

Then go to the folder where you extracted the pywallet files and open another command window. Here just type
Code:

pywallet.py --dumpwallet > wallet.txt

This command will dump everything from the wallet to a file in the same folder called wallet.txt. If you have a passphrase on the wallet, add the option --passphrase <passphrase> to the command after pywallet.py and --dumpwallet. Make sure there are spaces between them all. If the directory where your wallet is located is not the Bitcoin default, then you will also need the --datadir=<path to directory> option also added in in the same manner as the passphrase.

cheers,

10 minutes after I entered the dumpprivkey cmd:

2017-06-22 14:31:26 *** System error: CDB() : can't open database file wallet.dat, error -30974

19  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Wallet v0.8.6 beta on: June 22, 2017, 02:35:42 PM
The wallet immediately freezes so I cannot enter the wallet debug log file   Sad

Could you post the debug.log file?
You do not need to run the wallet to open the debug.log file. The file is in your DATADIR (the place where you normally find your wallet.dat file).

thanks,
got it   Smiley
