1  Other / Off-topic / Re: What wallets do you use? on: July 18, 2017, 04:50:27 AM
I use Exodus wallet since it's convenient built-in shapeshift.io crypto exchange and that it's a multi-cryptoCurrency wallet.
I'm not too sure about the ability to adjust fees  Huh

But I also use Ledger Nano S.

 
2  Bitcoin / Bitcoin Discussion / A bit of confusion regarding USAF / BIP148 on: July 18, 2017, 04:34:48 AM
Hi all,

I've read this part:


Quote
How do I prepare for BIP 148 if there is a split?

The most important thing you can do is perform your own network consensus by running a full-node and creating and storing your own private keys.

This means you will need to run a full-node for the legacy chain, likely Bitcoin Core, and a full-node for the BIP 148 chain, likely a fork of Bitcoin Core with the BIP 148 rules enforced.

This will put you in firm control of all decisions related to how you interact instead of having some third-party make those decisions for you.

Additionally, it is unknown how the legacy chain or the BIP 148 chain will be labeled.

This could lead to significant confusion in the marketplace so it is important for you to know exactly what you are buying or selling.

source: https://www.weusecoins.com/uasf-guide/

Why confused?
As a bitcoin owner, I'm not really sure what I should do. Currently, my BTC's are stored on Exodus wallet. I also have Ledger Nano S, but I didn't transfer my BTC over to my Ledger wallet.

What should I do?
Keep the coins where they are?
transfer them to Ledger wallet?

And after the 1st of September, what should I do then?


Thanks for the help!

Do read this post on the Important Ann section:

https://bitcointalk.org/index.php?topic=1836611.new#new

The gist of it: nothing to worry about as long as you're in complete control of your Bitcoins. Not sure what that means? The post will tell you what to do.

thanks, I'll read. I think it means to have your BTC on a wallet that provides you with your private keys, as oppose to exchanges.

if your fear is about bitcoin price and possibility of it going down then your only choice is to go back to fiat because history has proven that if bitcoin price goes down, altcoins will get dumped much harder.

however whether or not bitcoin price is going to fall remains to be seen.

That means that people have no faith in the companies behind those altcoins. Or, am I looking it the wrong way?
5  Bitcoin / Bitcoin Discussion / How are you preparing yourself for the 1st of August? on: June 23, 2017, 11:01:41 AM
Hi everyone.

So with the date getting closer, everyone is talking about BIP148, Segwit, Fard Hork and what not... I here some say to 'not trade few days before and few days after to let things settle down'.

Some say they'll sell their BTC before that date.

I was thinking to exchange my BTC with some other Altcoin, but I'm not sure which. Speculating only, if you were to exchange your BTC to some other coin because of that BTC split, what would you exchange for and why?

I'm thinking of exchanging to Ripple, but also I have my eye on IOTA, since I believe it will be the next big thing after Bitcoin.

Aside form BTC, I'm invested in other 9 coins. Small time investments.

Hi,

I'm currently mining Ubiq, using my 2x R9 290 with a combined hash rate of 58.7MH/s. I use pool mining at https://ubiq.suprnova.cc/.

I would like to switch to Litecoin. Is it profitable to mine it with these GPU's? (ignore power consumption for this argument)
If yes, then solo or pool?

Thanks!

I just signed up to theblocksfactory and I don't know how to proceed from there.
I have 2 AMD GPU's and I was wondering if it's possible to mine using these GPU's.

In any case, what should I do next to start mining for DIGIBYTE ?


DGB is using 5 algos = skein, groestl, scrypt, sha-256 and qubit ... for AMD i cant realy tell you, whichone is "best" but best answer you can get is:

try diferent miners (like ccminer sp-mod 1.5.81 or ccminer trpuvot rc2 or sgminer v5.3.1 etc) to find best hashrate on same algo ...
what i heard the best profit on AMD cards is Dual Mining ETH + anything what claymores miner support Smiley

Stay away from scrypt and sha256. Those are ASIC driven and gpus will not be able to keep up. You have a much better chance with groestl and skein which I believe are new and GPU only. But please do your own research to verify. I have kept my gpus on ETH and ZEC and don't know anything about these newer algorithms.

EDIT - My 12hr Invalid rate is 1.7%. That's not outstanding for btc but it's probably good for DGB.  The pool rate is 6%. I would be curious to here from other sha256 miners as to what their invalid rates are?Huh

Thanks for the help.

I wasn't able to succeed with this though.

Where should I download groestl from?
how do I set it to run on two GPU's?

Update: I think I got it working. But I'm not sure it it's right.
I used the updated kernel that I found in one of the threads.

I set it to 2 devices because I have 2 GPU's R9 290.
And this is the command I'm using:

sgminer.exe -k myriadcoin-groestl -o stratum.dgb-groestl.theblocksfactory.com:9003 -u [username].[workername]_diff128 -p xXx -I 20

Should I change the command?

Thanks for the detailed reply.

I have an android device, Oneplus One, which is rooted by me but have latest google security patches.
I have PIN code access to the phone and PIN code access to Mycelium.
The seed is backed up on text document which is zipped with a password on cloud storage service and printed on a piece of paper as well.


No problem.

Now for the issue.   You said you have the seed in a text document which was zipped.  This means the seed was actually 'online' at some point.  So, for the security concerned people, they would say (me included) that your machine 'could' have been compromised already.  You get the point.  Smiley

Good point Smiley
So... should I create a new wallet and back up the seed on a piece of paper?

Still, a person would require my pin code to do transactions, isn't it?

What OS do you run on your Oneplus One?

14  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: May 29, 2017, 10:47:59 PM
I opened a wallet in mycelium.
Is there a way to install this app on my wifes phone and share the same wallet?

I mean, what happens if she use the restore wallet and paste in the 12 words and private key? will this erase my wallet from my phone? will it sync them?

thanks!

Yes, you can install the same app on your wife's phone and entering the master seed to use the same wallet.
It's the same as both of you have the same access to write checks from a joint checking account.

Any transaction you make will also appear on her phone and vise versa.  They will both keep in sync.



So, one more question that comes to mind is what happens if my phone gets stolen and hacked?
Let's say it does, but in the meantime I use a second phone to restore my wallet using the exported extended private key and 12 words, I should see the same funds, right?
But so does the one who hacked my phone. What does one do in this case? Smiley

If your phone is stollen, and you don't have any security setup (example finger print or code AND the app isn't setup with another code), then the person could take all your bitcoin from all the accounts.  It's worse than a bank card that you wrote the pin on the back.  Just might as well have lost a wallet with cash in it.  So, don't be dumb.... setup a pin code (not 1.2.3.4.5.6)

Basically, keep the master seed on paper in a safe deposit box.  If you lose your phone (knowing someone can't get into it), then simply get a new phone and reinstall the app and recover from your master seed.

Note: bitcoins on a phone should be considered a hot wallet.  Meaning, funds in it should be what you need for day to day dealings.  Not a storage device with all your coins.

'Hacking' a phone isn't as easy as simply typing in digits until you get the right one.  So, a lost phone is safe if you went through setting up security.  If you want real security, then get a trezor / keepkey to use in conjunction with your phone.  (You didn't mention, that I noticed, which phone you were using (iOS or Android).)
I'm not sure from where you got the information's of backing up the extended private key but all you actually need is the seed (12 words), all private keys are generated from it so that's all you need to recover your wallet even after a few years from now. and see this[1] for more info.

[1] http://support.mycelium.com/hc/en-us/articles/207045535-How-do-I-make-a-backup-

There is no need (for most people) to backup the private key.  The seed (12 words) is what is needed to backup all the private keys the app makes.  A private key for a single transaction changes for each additional transaction since mycelium moves from one address to the next.  Yes, there are rare instances you would need a private key or even a master private key, but those are for very specific reasons.   



Thanks for the detailed reply.

hmm... I didn't read it anywhere. I thought that after I backup my wallet in mycelium, that I should also export the private key.
16  Bitcoin / Mycelium / Re: Mycelium Bitcoin Wallet on: May 29, 2017, 12:58:43 PM
Thank you. I'll try that.

a PIN code should be required to send the funds so whoever stole the phone, won't be able to take the funds. In the meantime, you can send your funds to another wallet you have so even If he manage to get the PIN afterwards, It would be useless because you sent the money somewhere and Its empty now.

Great! thanks for the tip.

I was thinking of using the Local Trader in mycelium and read the guide: https://mycelium.com/lt/help.html I then followed to the description of what is HD wallets.
Just to be really sure: All I need to do once I set up my 1st wallet is to back up the 12 words (master seed) by writing it down and also export the private extended key, and do it only once, not after every transaction or X days, correct?

So if in 2 years time I gained X bitcoins and I need to restore my wallet using master seed + extended private key, it will restore it with all the funds?

I have never tried this but It should be the same as Electrum. You should be both able to use the wallet with no problems and nothing will be erased from your phone.

Thank you. I'll try that.

In blockchain, there's an option to import an address under the Address menu. I tried to import my wallet from my old android app to the new wallet in Blockchain, However it appears as "Watch Only" and it doesn't really transfer the funds to the default Blockchain wallet I created.
I get a message showing "0 address was successfully transferred to My Bitcoin Wallet. Would you like to archive this address now?"

I then saw that the transaction fee takes away about $6AUD (bare in mind I'm only experimenting with $7.23AUD which is 0.00226BTC)
So, if I want to transfer my whole 0.0026BTC from one wallet to another, it tell me to use total available minus fee: 0.0017176 BTC, which is 0.0005424...

Does it make sense?
It also asks me for the private key of that wallet I have on my android device. I have not idea what is this private key.

Hi, and thanks for the prompt reply!

So I have installed MultiBit HD Desktop app, however, in addition I've create a wallet using https://blockchain.info which syncs with a mobile app. That basically caters my need to have a cloud storage and mobile app.
I think in this case, MultiBit HD app is redundant since I wasn't successful in creating the same blockchain wallet in MultiBit app.

Thanks for the help!
