8161  Bitcoin / Development & Technical Discussion / Re: Low transactions fees but fast on: September 29, 2017, 08:26:20 PM
I think the speed of confirmation is base on the volume of transaction in blockchain because right now since china closed some of their exchange it has a big effect of redusing transactions.
Whilst it will reduce the transactions a little, I don't think the closing of exchanges will have a huge effect on the number of transactions to be honest...

Most exchange transactions are "off chain"... It's effectively just people swapping numbers in the exchange's database... Only withdrawal and deposit transactions are completed on chain...

And despite the volatile nature of exchanges and security risks, most traders seem to ignore the warnings and keep all their coins on the exchange to avoid transaction fees etc.

Besides, most of the traders will likely just move to a different exchange if their normal one gets closed anyway Tongue

Did you run the installer as administrator?
Did you try running the app as administrator?
Possibly an overly aggressive antivirus?

Also, does your windows username use "special" characters at all? i vaguely remember some users having troubles because their username had non latin characters like Å or Ç or chinese characters etc...

Otherwise, I don't have any other wallets to recommend... Electrum is the best lightweight wallet imho.

You're going to need to do a bunch of reading:

https://bitcointalk.org/index.php?topic=1990373.0

Honestly, unless you have sent a significant amount of USDT to that address, it'll be less hassle to just write it off as a learning experience. It's going to be very difficult to recover and requires knowledge of and using commandline tools.

There is no "one button" solution to your issue Undecided

You're welcome Wink Oh, and say thank you to AntPool when they mine your transaction as well! Wink

Also, you may want to have words with your Exchange as to why they used such a low fee? Huh Or did you select a "low" option when withdrawing? Lips sealed Roll Eyes

If you exported your private keys from MultiBit Classic... you must ensure that you do NOT encrypt the export file using a password... otherwise, they multibit.key file will be encrypted and unable to be read by any other application/wallet and will look something like this when you open it in a text editor:




To get the private keys in plain text, use the "Tools -> Export Private Keys" option in MBC and then set it up using the following guide:


and then click the "Export Private Keys" button.


If you do it like this, then your multibit.key file should be a plaintext file that you can open in notepad etc to get the Base58 encoded "WIF" private keys that you should be able to import into the BCH wallet of your choice:


NOTE: due to all the added info in the .key file (# comments and DateTime stamps etc), you'll most likely need to copy/paste the keys into your wallet application... I don't know of any wallets that will simply import the .key file directly

8168  Economy / Gambling discussion / Re: Seuntjie' Dice bot programmers mode discussion. on: September 29, 2017, 01:36:35 AM
You could just create a 2nd "betcount" variable... and do the check and increment on that as well... so instead of betcount, use lowCount and highCount...

Code:
lowcount = 0
highcount = 0
...
function dobet()
...
  #check and reset on wins etc
...
  if lastBet.Roll < 99.34 then
    highcount += 1
  else
    highcount = 0
  end
 
  if lastBet.Roll > 0.66 then
    lowcount += 1
  else
    lowcount = 0
  end

  if highcount > 100 then
    chance = 0.66
    nextbet = previousbet*1.00725
    bethigh = true
    bettinghigh = true
  elseif lowcount > 100 then
    chance = 0.66
    nextbet = previoubet*1.00725
    bethigh = false
    bettinglow = true
  end

end
You will probably need to put in checks on the "bettingHigh = true" and "bettingLow = true" flags or you might find it switches from one to the other if both high and low hit 200+ streaks


One last thing... the "max expected" loss streak for that chance over 1,000,000 rolls is something like 1400-1500... so don't be too surprised when you suddenly hit a crazy 1000+ losing streak and find you've lost 0.1 BTC+ on your martingale #justSaying Wink
8169  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: September 29, 2017, 01:15:34 AM
Yes, this is correct. Mycelium did their best to cater for those using HD accounts and who wanted to "import" non-HD private keys.

- Master Seed is your backup for ALL your HD accounts.
- Encrypted PDF with the random passphrase is your backup for non-HD private keys.

I cannot comment on the Colored/Master coin thing, as I have not used these.
8170  Economy / Exchanges / Re: SENT USDT TO BCH ADDRESS on: September 29, 2017, 01:08:46 AM
Then you'd need your redeem script... and to create a raw unsigned transaction using the redeem script, the inputs with your USDT attached, sign it with your two keys... and then broadcast it to get your tether back...

I have no idea how to get the redeem script for the BTC.com address... maybe try contact their support team and see if they can help... if you can get the 3 public keys involved for creating your "3" address, you can probably follow this:
https://github.com/OmniLayer/omniwallet/issues/1314#issuecomment-243222850

It should be noted that when putting the public keys in, they need to be in the right order (ordered by number/letter, ie 02a before 02b before 03a etc) to generate the correct address/redeem script...


Also, these guys had similar issues with MAID and a bitcoin address which is somewhat similar to your situation:
https://github.com/OmniLayer/spec/issues/224#issuecomment-238381409
https://github.com/OmniLayer/omniwallet/issues/1314

It gets very technical, very quickly... and I've not actually performed any of these operations... you may be better off contacting the users who were helping on those Github threads once you have the redeem script sorted out.
8171  Bitcoin / Electrum / Re: Electrum on: September 28, 2017, 04:28:13 AM
Which version of Electrum did you download? And where did you download it from?

It is weird that it will start up and get as fair as asking for your password, but then the wallet doesn't open... It might be that you have some corrupt data in the Electrum data directory.

Have a look in: C:\Users\YOURUSERNAME\AppData\Roaming\Electrum

If you have you 12 word seed mnemonic, you can simply delete everything in that folder, uninstall Electrum and then try reinstalling and creating the wallet again. If you don't have the 12 word seed mnemonic for you wallet, then backup the "wallets" folder, then delete everything, uninstall and reinstall Electrum.


(NOTE: If you can't see the AppData directory, you need to show all the hidden folders: https://support.microsoft.com/help/14201/windows-show-hidden-files)
8172  Economy / Exchanges / Re: SENT USDT TO BCH ADDRESS on: September 28, 2017, 02:28:45 AM
Ahhh ok... so you've sent your USDT to a MultiSig Wallet... that complicates things...

You need at least 2 of the keys used to create the "3" address... do you have them? Or do you only have access to 1? I don't have much experience with BTC.com wallet... but it doesn't look like it is very easy to export your keys/funds out of that wallet Sad

8173  Economy / Service Discussion / Re: XAPO are now allowing people to withdraw their bitcoincash on: September 27, 2017, 08:57:29 PM
But they're setting a deadline of December 14th 2017. If you haven't withdrawn or sold by then, you lose your bitcoincash coins.
It's a smart move from them. Most people won't see it and then they "forfeit" their right to those coins which XAPO then gets to sell.
That's not exactly true... they're simply going to convert them into BTC at the going rate and deposit to your account.


What will happen if I decide to keep my BCH? Will Xapo allow me to operate with Bitcoin Cash?
Xapo will not support BCH in any way after December 14th, 2017. Users will have until that date to decide if they want to sell or withdraw their BCH. If you do nothing with your BCH by that date, then Xapo will automatically sell any remaining BCH balances for BTC and credit the corresponding value in BTC to the customer's wallet.
 
What will happen if I don’t withdraw or sell my Bitcoin Cash by December 14th, 2017?
You will not lose your coins and Xapo will not keep unsold Bitcoin Cash for itself.
 
If we receive no further action from you before this date, your Bitcoin Cash balance will automatically be sold and the value will be added to your Bitcoin wallet.
 
Please note the amount received will reflect the market rate at the time the sale is executed.


TL;DR:
Sell or withdraw your BCH from Xapo before Dec 14, or they'll sell it on your behalf at "market rates" and put the BTC value into your wallet...
8174  Bitcoin / Electrum / Re: Has anyone been able to send a transaction using Electrum/ Electron Cash so far? on: September 27, 2017, 06:47:20 PM
If you have lost your seed, then your chances of being able to get the BCH out of Electron Cash is not good.

2FA is a 2-of-3 MultiSig account. Easiest option is to sign with the two private keys generated by your seed. But in your case, No seed = Not able to restore and disable 2FA to get 2 private keys = Not able to send BCH

Maybe you can contact TrustedCoin like the previous poster? https://trustedcoin.com/#/contact-us

If you ask them nicely, they might be able to help you out and sign the transaction so you can move your BCH out of 2FA wallet.

8177  Bitcoin / Electrum / Re: exporting private key from wallet with 2fa on: September 27, 2017, 05:03:03 AM
Unfortunately, it isn't just about getting the 2 private keys out of Electrum... that part is easy... you simply restore your 2FA wallet using the 2FA seed and "disable" the 2FA when prompted to "Keep or disable"... don't put a password on the wallet file, copy paste the two xprv's from your unencrypted wallet file into the BIP39 tool and use a derivation path of m/0... et voila, all the "1" addresses that form components of your "3" address are created.

The difficulty comes from the fact that MAID is essentially a token running on Omnilayer... and while you can easily send a transaction from your 2FA wallet that will send Bitcoin, there is no way for you to create a transaction in Electrum that will move the MAID.

So, as far as I can tell... you need to:

1. Get your 2 keys from your 2FA wallet for the address containing MAID
2. Install and Sync Omni
3. Create a raw, unsigned transaction in Omni that shifts the MAID from your electrum address to somewhere else (and includes a small amount of BTC)
4. Sign the transaction using the private keys
5. Broadcast the transaction
6. Live happily ever after Wink

8178  Bitcoin / Development & Technical Discussion / Re: Why I Am Not Using Hardware Wallet For Cold Storage on: September 27, 2017, 04:36:38 AM
Alright, has HCP lost the debate?
No, I just got tired of trying to explain things that you didn't seem to be comprehending.

You keep inventing more and more convoluted scenarios to try and do "end-runs" around logic and reason... like how a supposed attacker has full access to my entire Bitcoin transaction history and knowledge of every single one of my addresses... so they'd be able to determine whether or not passphrases being provided are "real". Which, of course, is defeated simply by running any cold-storage funding transactions through a mixer etc. and using my "decoy" wallet for day to day transactions.

In the same scenario using your system... exactly the same thing would happen... except, if they've found a bunch of encrypted files and ask for the password, you have no defense. They can see the files, they know they exist, they know there are passwords that decrypt them and will know instantly whether the password you give is correct. With a hardware wallet using a passphrase, there is NO evidence that the wallet exists... because it doesn't until you enter the passphrase.

And this is what you don't seem to want to admit... there is NO 100% secure method of securing your stuff. I admit that hardware wallets are not perfect... there are still attack vectors... just like with your system... but a hardware wallet helps minimise these and provides, in my opinion, a number of benefits that your system doesn't.


You even claimed at one point that your method is "unhackable" Roll Eyes
Hard to hack? My approach is not even hackable.

Then conceded that nothing is safe:
Well, on 2nd thought, I guess nothing is safe. Or else there would be no Matthew 6:19-21.

And then denied that you conceded that point...
I just don't think it is as secure as you believe it to be (a point you eventually conceded)
I never conceded. You are talking nonsense. My method is better than both hardware and paper wallets combined for cold storage.


You then descended into just calling every one of my points "Bullshit"... calling me an idiot, dumb nut, silly and a low life and accused me of just being a trouble maker
That's not even the point, you silly.
Your argument is bullshit.


You are clearly a troublemaker.
You will be a scum that will appear out of nowhere and say "No, a ball is circular."


That's not even the point, you silly.

You are clearly a very very stupid person.
You are a bullshit.


For that, I say you are a bullshit.

Bullshit.
...you dumb nut.


Bullshit.
For this, I say you are a bullshit.


I don't mind if you are a smart person. In fact, I would be very happy if you are smarter than I am. At least I can learn from you.
But if you are a stupid jackass pretending to be some smart ass, then I don't wish to be troubled by a lowlife such as you.
Personal attacks aside, that's not how you "win" a debate...



Then you started down the whole "hardware wallets are more inconvenient because you have to remember a passphrase AND a PIN" path... I guess I should have just pointed out at the time that with your setup you potentially need to remember a whole bunch of extra stuff as well, like your email account+password where you stored your backup... or your online storage account+password where you stored your backup... or where you put that CD with the backup data on it... because that is just as "difficult" and "inconvenient" as remembering a 4-8 digit PIN Roll Eyes



And now you also seem to think that for some reason hardware wallet users are forever tied to hardware wallets:
With a hardware wallet, the owner will have to keep buying a new one if the previous one is lost. HCP argued that's not the case, but of course if the owner wishes to continue using BTC for cold storage plus spending, he has no choice but to spend for a new hardware wallet.
Which is just plain wrong...

If I lose my hardware wallet... I can simply take my seed backup and generate a paper wallet or import it into a software wallet or import it into a web wallet should the need arise... or simply do nothing and continue using those addresses as cold storage knowing that I still have access to all my coins should I so require in the future.



TL;DR:
I prefer hardware wallets as they offer all the benefits of cold storage and provide added security for hot wallet/day to day spending in a handy, convenient, portable package that still provides me complete control of my private keys, at a relatively reasonable price for anyone with modest/substantial amounts invested in cryptocurrency.

Dorky prefers his digital version of paper wallets as he believes it provides the benefits of cold storage with the best security at near to zero cost, without some of the issues associated with paper wallets (like susceptibility to loss/damage/theft) while still maintaining control of private keys.

Neither method is 100% secure.
8179  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: September 27, 2017, 03:00:34 AM
Mycelium uses BIP39 and BIP44... it uses a Derivation Path of m/44'/0'/0'/0 for receive addresses and m/44'/0'/0'/1 for change addresses (for the default account in Mycelium)...

- Put 12 word seed into here: https://iancoleman.github.io/bip39/ (<insert standard warning about using offline copy here>)
- Click BIP44 tab
- See all your receive addresses AND private keys at the bottom at the bottom (generate as many as you need to find all your coins)
- Change "External/Internal" value from 0 to 1 for change addresses
- See all your change addresses AND private keys for those addresses at the bottom (generate as many as you need to find all your coins)

The xprv and xpub are all generated from the seed... the 12 words are a less error prone method for representing the seed...

For different "accounts" in Mycelium you can just increment the "account" part of the Derivation Path:
m/44'/0'/1'/0 and m/44'/0'/1'/1 - Receive/Change for Account1
m/44'/0'/2'/0 and m/44'/0'/2'/1 - Receive/Change for Account2
etc

If the wallet for the forked coin has full HD functionality, then maybe you could fork your coins by doing a wallet restore on the forkcoin wallet.  I haven't seen that, but then I haven't seen everything.
You mean like how everyone could just restore their 12 word seed into Electron Cash to regenerate their Mycelium and/or Electrum wallets to access the BCC after the fork? Roll Eyes


Personally, I'd rather write down (and double check) 12 words than attempt to make sure that I have transcribed something like: xprv9s21ZrQH143K2EQNBSLkWK1tSFmwprbUHff8sFGVmC4J4qMdJvNR2DVZyaaxA4kHS9hzx4fYtp2 HsXhqFW6UGuB15CotXZrF1uzikqX75nN correctly... but that is just me Tongue
