Summarizing....
We thought of everything. Generating a guarantee letter requires location a private key from the wallet that creates the signature on the server of mixer. In case the mixer is compromised, its customers will be able to give out fake addresses and fake guarantee letters. We sign the addresses that we give to clients on computers that are not connected to the Internet, then we unload the signatures together with the wallets at our server. This ensures that addresses given to customers can in no way be compromised by a third party (intelligence agency or hackers), under the term that the client will verify the signature.
Are you saying that when I go to your mixer and start mixing, you or one of your employees sign the Letter of Guarantee manually in the offline PC? 24 hours a day? |

Got hacked too. Is it still safe to use my Electrum account if I change the password? Not sure exactly how the hack works and if they will still be able to access account.
Wait. If you got hacked, it was probably because: A) you downloaded a fake Electrum from somewhere. B) your PC is infected with a malware. In any case, you SHOULD consider your PC and wallet compromised. Reinstall your whole OS, download Electrum ONLY from ELECTRUM.ORG and create a brand new wallet. This vulnerability explained in this thread was fixed months ago, so probably it doesn’t have anything to do with your case. |

Está demorando mundo a popularização da lightning network. Eu acho que ainda está muito complicada para quem é leigo no assunto executa-la. Muita gente tem medo de perder seus bitcoins na transações. Isso que me parece.
Eu acho que é mais por causa do tipo específico de use-case da LN. Digamos que você queira comprar uma camisa com o carinha da montanha russa do BTC. Você tem que abrir um canal com o dono da loja, esperar a transação confirmar e então, ai sim, fazer a transação pelo LN. Além do mais, pra gastar esse BTC recebido e pagar suas contas, o dono da loja tem que fechar o canal, esperar outra transação, e depois mandar seus BTC pra exchange. Sinceramente... acho que o LN só pode ser realmente “util” para serviços que fazem múltiplas microtransações, por que mesmo pra usar você tem que fazer uma tx normal pra abrir o canal. Pelo menos foi isso que entendi dele. |

^ in that case, he will also need to log every merit transaction in the mysql database. It’s possible to make an API without an sql server. Idk if Loyce knows mysql. But he already doesn’t know PHP, so that would just complicate his life.  I’ll give a shot on making the API. |

We have a banner at the top of our post due to one person's negative feedback:
I can't see that? You don't have any active flag nor any negative trust from a DT user. |

I’d love one of those to play around with my projects.
Sadly they probably don’t ship to my country and all resellers here try to sell them for at least 3x their price. :/

The minimum fee for Android Electrum Wallet is about 25 s/b now, can I make it smaller?
If I can, how?
You can. Try playing around with the fees settings (click the three dot at the top-right -> settings -> fees). |

Thanks for getting back. I did transfer the funds to Trezor but was confused to still see the private key in Electrum. Did transferring the funds create a new private key in Trezor that contains the funds?
Trezor will generate its own addresses (and consequently private-keys). They will never leave your hardware device, so that's why they are WAY more secure. You sent the coins from your Electrum address to your Trezor address (different addresses). |

Yikes. My Dell XPS 15 came with this software. Thankfully I installed Ubuntu right after it arrived. Crazy how there are so many vulnerabilies everywhere (VLC, DELL software, ...) that goes unnoticed. Anything can be vulnerable to attack vectors.  it's sad how we can't just say anymore that we are safe as long as we don't download random stuff over the internet. |

Acho que isso já acontece. Cado o Bitcoin fosse altamente escalável (centenas ou milhares de tx por segundo), com certeza já estaria com um preço muito mais elevado e 95% das “top altcoins” seriam totalmente inúteis (mais do que a maioria já é).
Na verdade eu acho que esse provavelmente é/vai ser o maior problema do BTC e o que diminui as chances dele ser a moeda global e não um método de pagamento escalável como o VISA ou até mesmo o Libra.
Mesmo gostando do LN, não acho que essa será a solução do BTC e sei que ele pode ser péssimo para certas situações.

All you did was import your Bitcoin address as "watch-only", which - like the name says - can only be used to watch/see the balance and transactions of that address.
The only way you can recover your coins is if you remember the password... OR if you saved your wallet backup seed (or wallet file in older versions of the Blockchain.info wallet). Did you?

Sorry for your lost, OP. :/
But if it's any consolation, I'm spamming his website with fake wallets so if other people fall for it, he at least can't find them in the list of thousands of seeds.

Yes... You can do that with Bitaddress (check the 'Brain wallet' tab). Download its source code and run offline. But note that this generally isn't the best idea. See this. |

Nossa, muito legal todas as respostas aqui de vocês!
Gente, eu comprei o Bitcoin lá na MercadoBitcoin, mas não gostei muito da interface dessa exchange, não tem gráficos para analisar, e vi que o pessoal fala que as taxas dessa exchange é uma das mais altas...
Então... Já que tenho o Bitcoin agora...
Quero ir pra outra Exchange, qual a melhor forma de fazer essa migração?
Pois já deu uma valorização de 12% em 24hs que comprei o Bitcoin, o melhor seria primeiro vender ele na MercadoBitcoin pra sacar em fiat pra colocar em outra Exchange? Ou fazer uma arbitragem?? O quê??
As minhas favoritas com certeza seriam a BitcoinTrade e a Walltime. A Walltime principalmente quando eu quero vender e receber o dinheiro rapidamente. A última vez que eu solicitei um saque, ele foi executado em literalmente 5 MINUTOS. E isso em um sábado! 5 minutos e o dinheiro estava na minha conta. Não use o MercadoBitcoin. Eles são uma das piores exchanges (passado sujo e muito duvidoso, taxas altissimas - eles tinham taxa pra depositar!!! (não sei se ainda tem) - etc...) |

There are no minimum or maximum. Bitcoin pumped another 10% in just 24 hours. This makes a lot of people make transactions in order to sell their BTC or send their bought ones to a wallet. A lot of tx in a small space of time fills the Bitcoin mempool, making the average fee to increase. What does that mean is that fees are dynamic. One day it could be at 1 cent, and then the mempool fills up and you need a $3 fee to get a confirmation in the next block. I recommend that you always check the recommended fee on: https://coinb.in/#feeshttps://bitcoinfees.earn.com/And maybe even wait to send your tx or send it with a smaller fee (which will take time to confirm) if you’re not in a hurry. |

Hope it fits the needs.  Is this something I run on the server? (complete n00b here) Call this file anything-you-want.php and just upload it in the same folder as the merit.all.txt file. But if you don’t want, I could try making my own as well. I thought I had to scrape each user merit page or similar. Edit:@Loyce how do you get the name of the users and posts? |

{bear in mind that im not usa citizen, so please base your answers on that, i am european citizen.}
1. will i be able to download coins from 2 separate wallets with ledger nano x, and keep them there or it's 1 wallet 1 ledger?
The Ledger Nano X has waaaay more storage than the Nano S. You will be able to download every coin you want and use all of them in the same Nano X. Just open the right wallet and select the coin in your Nano X screen. 2.are there any sites where i send xlm, and they send fiat currency to a credit card? i remember there was 1 site that did that few months ago, it didn't support my country, but i assume if there was 1,there are more? for instance id like to send 1k dollars to someone in africa, i send to that website 1k worth of stellar, and they send fiat to designated credit card of my recipient?
I’m not aware of any XLM prepaid debit card (which I assume that this is what you're asking for). IIRC, there was a company called Pundi X, but I don't know how they are now. 3. is trust wallet good choice for keeping erc20 and bep2 tokens? their GUI is somewhat clanky for me, i dont like it too much, thats why im asking if there is a wallet with same functionality but with smoother GUI.
Try MyEtherWallet. They support ERC20 tokens and let you connect your Nano X. Soon, the Ledger Manager will be able to do that as well. 4.Im currently using CEX to buy and sell my crypto with fiat currency via credit cards, any cheaper or better alternatives?
Credit Cards are always the MOST EXPENSIVE way of buying crypto (due to the huge card fees). Have you thought about using an exchange to deposit fiat through Wire or something like this and buy it from there? (E.g Bitfinex or Kraken). Unfortunately none of those exchanges work on my country (only local specific ones), so I can’t help you with that. But there are many exchanges around there. You just have to research about them. |
