Well, for use Skrill, I think there has a high fee. but, if they start accepting bitcoin, I think it is very good news. but, I think they'll give you a high fee even though they accept bitcoin. but now I also have not seen the news that Skrill accept bitcoin  . Skrill has indeed high fees, but I don't think many people will be bothered by that since it's nothing more than an alternative way of buying Bitcoin. In some cases people end up buying coins at a fee of around 5-10% due to the fact that they haven't got any other option than this. Just to be clear, Skrill itself doesn't accept Bitcoin. Skrill just seems to have a friendly policy towards crypto in general which of course is a nice change for once. You can only deposit BTC into your skrill account. You can't withdraw money from your skrill account in the form of bitcoin. It's quite typical really. Everyone is happy to take BTC because it is an irreversible payment method but few will give you BTC in exchange for your dollars. |

Since electrum is a deterministic wallet it is possible to derive all the addresses in the wallet with the extended public key which is also known as the master public key (MPK). You cannot derive private keys with just the MPK and without the private keys you cannot spend your bitcoins. So it is safe to install the MPK on your web server and let it generate addresses for users to send money to without any risk of theft. This is how bitcoin payments for woocommerce does it. It is also how mycelium gear works. It is how you should do things too. You haven't mentioned which shopping cart software you are using? Perhaps there is a bitcoin plugin for that. Otherwise I can point you to opensource deterministic address derivation libraries in the programming language that cart is written in so you can make your own. |

On bitcoinspakistan.com, why there is no any option/info for urdubit.com while it is much better place for selling and buying bitcoins in pakistan.
because i don't trust them so i can't recommend them. |

your math probably isn't correct because it is supposed to take until the heat death of the universe even if you use all the computers in the world non-stop  . you're using just 1000 asics in your example. part of that seed mnemonic is actually a checksum so you have to discount that. once you remove the checksum you find it's a 124bit seed. so 2^124 possibilities. |

And, I've tried on quite a few different occasions to restore my wallet using the seed that I took a picture of but it's not working. I hit restore, enter the seed (exactly as shown in the pic I took) and I have to name the wallet and then it says/shows "loading wallet/s" and when it's done there is no money in my Electrum wallet, it's kinda like I created a brand new wallet instead of restoring my old one.
Install electrum on a desktop pc and run it. Choose to restore from seed and restore your wallet. Then after that is done press ctrl+A or select addresses from the wallet menu. A new tab labeled addresses should appear. Go there and expand the list of "used" addresses by clicking on the arrow/+ sign next to "used". Can you see any familiar addresses there like the HEL one? |

Hi guys i would like to ask if how we can know the size of transaction before we send bitcoin to the target address. so that i can put my manual fee for better speed of my transaction.. i notice sometimes my transaction with the same amount but different size that actually it takes time before its confirm.. So i am looking how to know it but i could not find it.
I have an idea. Use the preview option on the send tab. Sign the tx. Then use the copy option to copy the hex code. What next? Is the hex code saved to an ascii text file going to use the same amount of space as on the blockchain? i'm not sure but maybe this will get you half way there. |

The developer actually doesn't recommend the portable version. I suggest going with the windows installer version. Why are people so afraid of using that? On windows installing software is as easy as clicking next, next, next!
Actually I do like to do the installer version like qt client, and have a feel of holding the backup of the wallet file  But the name "portable" sounds so convenient. I can just bring a usb stick and move around without a need for the full machine when travelling. Why is it not recommended btw? If you need portability you should get a second wallet on your mobile. Mycelium is popular for that purpose. |

You guys need to go take a look at the mycelium thread: https://bitcointalk.org/index.php?topic=293472.0Those guys still haven't gotten their own sub-forum although they very much deserve it. One of the top bitcoin wallets operates out of a single thread! |

Thanks @longbob72
@Abdussamad, What are you trying to advise me from that link? Basically what I gather from that link is about backup and restoring at the wrong place.
I just wanted to point out that you can create shortcuts to open specific wallet files using electrum. That'll make it easier to run two different wallets at the same time. And because you will always be opening the wallets using the shortcuts you create you can never mistakenly use the wrong wallet (as the OP in that thread did). From what @longbob72 had mentioned, I could just safely restore from seed, hence can ignore the backing up of wallet file and hence no headache from restoring at the wrong place. Am I right here?
Restoring your wallet from a seed backup does not restore labels for transactions and addresses. You can enable the labels plugin to store those labels encrypted on a remote server. But I think it is better to keep a copy of the wallet file too. |

You can use the -w switch to make a shortcut to your specific wallet file: electrum -w c:\path\to\wallet
I may have lost 3BTC because of this fucking shit.
Sorry to hear that. Others have complained about this too in the past. If you are not using the default wallet then you should just move it out of the electrum folder that btchris specified above. Electrum does list the wallet file name in the window title so you should pay attention to that. |

where are you downloading electrum from? the official site is at electrum.org I'm having a really annoying problem, I was using an old version of Electrum and the program said I cant transfer bitcoins using versions under 2.5 build.
this sounds strange to me. when does the program say this? |

Actually skrill allows BTC deposits indirectly, let me explain you. You can open a neteller account and deposit with bitcoins there ( they take just 1% fees ) then then you can upload from neteller to skrill ( the fees is 3% ) so actually you get BTC to skrill at just 4% fees.
You can now directly deposit money via btc into your skrill account. The fee is just 1%: https://i.imgur.com/MlEeA4n.jpg |

Some days ago I saw a thread about it: https://bitcointalk.org/index.php?topic=1699023.0But looks they just accept it informally via neteller or any other service offering itself as middle-man to complete the transaction. Do Bitcoin option appear directly in Skrill site for you? I can't see this. Or that is why what I said above, or because my country doesn't accept this. yes it appears directly: https://i.imgur.com/MlEeA4n.jpg |

Skrill now lets you upload money to your skrill account using bitcoin. The fee is 1%. The option is right there on the upload funds page. Go take a look if you have a skrill account!

guys i can't afford your premiums. please take a look at my ad to see the sort of prices i'm looking for. if you can't sell at that price then please don't bother posting in this thread.
Skrill can chargeback- hence the premium Yeah I'm aware of that but I've already purchased at that price before. I mean the price relative to bitstampusd. |

I understand that the xprivkey (the master private key) is derived from the seed, and that no information is lost when calculating the xprivkey from the seed.
Well it's run through hashing functions so I wouldn't say no information is lost. By definition hashing functions will take input of arbitrary size and output a number of a fixed size. You can't convert the output of the hashing function back into its input. That's why they are also called trap door functions. I believe that you can generate the same wallet from either the seed or the xprivkey
Yep that's true provided you know the algorithm used to generate the xprivkey from the seed. |
