I've seen in people's tutorials that they use both RSI and MACD in their charts. Since both RSI and MACD are momentum indicators, what is the advantage of using them both?

I'm a Post Graduate Computer Engineering Student in India. I'm learning things about blockchain, and wish to do PhD in a topic involving Blockchain. Although, given the rate at which things are evolving, I'm not able to choose the topic in this fast changing technology. Do you have any suggestions?

Whales, big miners, or those who hold huge amounts of bitcoin, if bitcoin becomes mainstream, won't big holders be like ultra rich people in today's world? Some holding lots of money, whereas some very less?

It is no problem at all to mine with cpu and gpu together in same computer. I did that in my mining rig without any coin issue.
Can you share the names of the miners you use and the little about the hardware you have? |

Is it possible for two miner softwares to be running on a machine? One doing CPU mining, other doing GPU mining?

I have a PC, Intel i5, with a Nvidia GPU, which I'm using to mine an Altcoin. I'm not using the PC for any other task. The PC's been running 7 days straight now running the miner software. Will running it continuously for many weeks or so damage the PC?

I just have one question. Why do I have to create a transaction on an online computer and then transfer the transaction to offline computer. Can I not just create the transaction on the offline computer?

So this is what I've figured: - Generate private key, address offline from bitaddress.org. Make paper wallet
- Send btc to this address
- Setup Electrum wallet with a seed on offline and online computer.
- SWEEP the key into OFFLINE Electrum wallet. This will not import the key, but transfer the bitcoins from that address to the electrum wallet address.
- Sign an offline transaction made by Electrum (to send some btc to a exchange)
- Execute the signed transaction on Online computer Electrum
Am I doing anything incorrect? So complicated and so useles. Can't you see the very first step ruins it all? Using online service to generate paperwallet is bad decision. Try it this way. 1- Install electrum to OFFLINE DEVICE, generate address&key pair, print it and DELETE THE WALLET - Now you have created a paper wallet. 2 - Send BTC to this address. - Now you have paper wallet with BTC. 3 - Instead of SWEEP ( which will cost you transaction fee) use the IMPORT to OFFLINE DEVICE with wallet - Now you have offline wallet where you can sign the transaction. 4 - Sign the transaction and DELETE the OFFLINE wallet. - Now you have signed transaction 5 - Copy SIGNED TX to any ONLINE device with and push it (no need to have wallet installed here, use any pushing service e.g blockr.io ) Note that importing address to offline wallet not ruin the paper wallet itself. You can use it again. Step1 - How do you print address and key from Electrum? |

So this is what I've figured: - Download bitaddress.org and copy to offline computer. Generate private key, address offline from it. Make paper wallet
- Send btc to this address
- Setup Electrum wallet with a seed on offline and online computer.
- SWEEP the key into OFFLINE Electrum wallet. This will not import the key, but transfer the bitcoins from that address to the electrum wallet address.
- Sign an offline transaction made by Electrum (to send some btc to a exchange)
- Execute the signed transaction on Online computer Electrum
Am I doing anything incorrect? In the SWEEP the key into OFFLINE Electrum wallet step, since the wallet is offline, Sweep won't happen, right? What should I do then? |

Entering your private key into an online computer kind of defeats the whole purpose of cold storage. The best way is to sign a transaction using an offline computer, copy the signed message and then broadcast it.
It is best to be paranoid while dealing with bitcoins.
Thanks! So to sign a transaction using an offline computer, I would need a bitcoin wallet installed on Offline computer. Right? If I just have a paper wallet, then? |

Suppose I have lot of bitcoins on offline generated address and private key stored on paper wallet. Now I want to spend/sell these bitcoins. What are secure and effective ways to do this? I will need to load the bitcoins at this offline address into some wallet (say Electrum). So do I need to load all the bitcoins, or only some? How do I do it? So I have to EITHER sign an offline transaction made by Electrum (for sending some btc to an exchange) http://docs.electrum.org/en/latest/coldstorage.html or SWEEP them to Electrum on online computer (send all btc to electrum wallet) http://docs.electrum.org/en/latest/faq.html#can-i-sweep-private-keys-from-other-bitcoin-clientsAm I right? What the ways to spend such large number of bitcoins on offline address and private key? |

Suppose I generate an address offline, using something like bitaddress.org
And then I receive some bitcoins on this address.
How do I know how much balance do I have on this address?

Suppose I hold lot of bitcoins in exchanges and in some wallet. To prevent the loss of bitcoins, how should one manage them?
Generate multiple new addresses. Distribute the bitcoins among these addresses. Copy the private keys of these addresses to paper wallet.
Is this the way to do it?
What are other better ways to manage large number of bitcoins?

I have exported my Private key to Paper Wallet. Now, when we send/receive bitcoins, we send/receive them to an "Address". So suppose I receive some bitcoins on my address. I have the private key of this address. Now I want to spend the bitcoins I received at my address. For this I need to import my private key to some wallet. Am I right?
And even though I'm importing my private key to the wallet, how will the wallet know what is my "Address"? Because I'm just importing the Private key, not address. Is address derived from private key?
I'm confused with this.
