How did you try to install the drivers? I could successfully setup a machine with this. sudo apt install nvidia-cuda-toolkit
sudo add-apt-repository ppa:graphics-drivers
sudo apt update
sudo apt install nvidia-396
If you also want to compile the ccminer, you will need a few more steps. I don't remember the exact steps, but I really do appreciate these! One addition, you can use sudo apt install nvidia-current to install the current version and don't have to manually upgrade it everytime. |

This is for bitcoin, every altcoin can change this and the algorithm which is used to adapt the difficulty. |

Thank you for this detailed instructions. After a few initial parse errors I was able to create the transaction with createrawtransaction "[{\"txid\":\"id\",\"vout\":n}]" "{\"address\":amount}"
I just had to escape the double quotes. |

I have a staking wallet on a small VPS with a high amount of small inputs and would like to combine them. Due to the low hardware resources I am running only the wallet daemon without GUI. Is there an easy way to combine only the small inputs (I don't want to lose the weight of the larger inputs)?

Yes, it's possible. There are already many decentralized wallets available (not all of them are available on the app stores). DeepOnion for example has a mobile app which is decentralized and runs over the tor network.

with a rasberrypi you have to run a pruned node, or connect an hard disk via usb2(there is no usb3)
with a bananapi you have a sata port so you can connect the hard disk directly. So with a bananapi you can run a full not pruned node. Everything else is almost equal.
I don't like pruned node because, if for some reason I have to perform a rescan I have to download the entire blockchain another time.
Also Im not sure if pruned node relays blocks.
Why would you need to run a pruned node with raspberry pi? just run a regular node. Also, pruned nodes only relay latest blocks received, but not the whole blockchain. because the sd card is too little, I don't know if an sdcard is able to store 150gb of data. usb is very unreliable and you end up with a corrupted blockchain. OK, now I understand your concerns. There are many sd cards with a capacity over 150 GB, it will costs just about 100€ and then you can run your full node on a raspberry. Thanks again, I will use mine for it. |

pruned nodes sucks, you should buy a bananapi with sata port.
I don't understand your point. The performance of the raspberry and banana are similar and I don't think the disk speed will make much difference (except for the initial sync). It was not about performances, I don't like pruned nodes, it is only a personal opinion. better pruned nodes than no nodes at all. I still don't know what you mean. Why would it be a pruned node? Who would notice a difference? What's your definition of a pruned node? |

Initial synchronization on a raspberrypi will take some years.
Good suggestion, thank you. |

This are good reasons to run a full node, but are there any security concerns when running a full node? I can think of one issue, your IP would be visible to the network and therefore you are maybe a target of an attack. Is this a reasonable concern or am I too careful? Are there other concerns?
start your daemon using: onlynet=onion bind=127.0.0.1 listenonion=0 Thank you! I didn't know that the bitcoin core wallet supports to run over tor without much configuration. https://en.bitcoin.it/wiki/Setting_up_a_Tor_hidden_serviceAny other concers? Otherwise I will setup a full node on my raspberry  |

Never experienced this, but it would be quite helpful to get more details about your transaction and the error. - Could you provide at least the transaction id?
- How much did you set as fee?
One idea would be to import the address into another wallet and test it from there again. |

Yes I agree I think it is unning a Bitcoin full node isn’t just for mining pools and companies. Today, we’re going to outline 6 reasons why the average user should also consider running their own Bitcoin full node. There is a list of 6 reasons to run a Bitcoin Full Node.
1) Helps the Network
Running your own full node is the only way to have full control and to ensure that all the rules of Bitcoin are being followed. Nodes do this by rejecting blocks and transactions that don’t follow the consensus rules and by rejecting connections from peers that send them (or too many of them).
2) Keeps you safe
Running any kind of Bitcoin wallet that does not require you to run a full node means that you have to place a certain degree of trust in the service provider, something that shouldn’t be necessary with Bitcoin.
3) Allows you to choose
In the possible event of a hard fork where both blockchains remain active with economic activity on each side like the one in Ethereum/Ethereum Classic, running a full node is the only way you can validate the rules of the new or old blockchain, according to your preference. If you don’t run a full node, your opinion will not be considered and you will simply follow the blockchain that is given to you.
4) Gives you a higher degree of privacy
Using a centralized, lightweight or even SPV wallet will never be as private as running a full node. Since you rely on third-party servers to broadcast your transactions for you, those servers will be aware of which addresses belong to you.
5) It’s not that hard
To less than tech-savvy users, running a full node may seem like a challenge. However, running a Bitcoin core full node is nothing more than simply downloading the latest Bitcoin core client version and running it.
6) It’s not that expensive
Running a node will require you to keep your computer on at all times – or at least for the majority of the day. While you can always turn your node on and off at will with this option, it is not a very practical one. Thank you.

The standard bounties are not paid good anymore, because there are just too many participants.
You have to stand out from others. Why should everyone pay you to advertise their coin for them? Do you have lots of followers on social platforms, do you have a high rank on bitcointalk, do you have something that is unique?
I am pretty sure that youtubers get good paid if they can advertise to the wide mass.

Only signature campaigns. Currently the 'salary' you can earn is just unbelievable low. There is so much dumping, people are literally working for a few dollar per hour.
It seems also stressful and you often read that everyone is replaceable. Better go for a regular job and invest in crypto.

19 Pages of responses with maybe good sources. @IsaakPooo did you make a list of the top sources for yourself and are willing to share this here?

Close your wallet, open the Electrum folder (%appdata%\Electrum) and delete (or rename) the blockchain_headers file. Then, just open Electrum again and wait for it to synchronize.
All sorted thank you!! What was the actual problem? Could you fix it with the above approach? |

I never liked EtherDelta, the site is slow and on some browser it doesn't load at all. But of course, I like the idea of EtherDelta. I tend to use CryptoBridge as DEX, it is also for coins and not just for tokens. Unfortunately there are often not that many open orders compared to centralized exchanges.

One backup is not always enough. The first time you start your qt wallet it will create about 100 addresses with private keys for you, but only one of it will be visible.
The keypool has been increased to 1000. The wallet maintains the keypool at 1000 as long as your backup is from a recent version of Bitcoin Core. It's generated every time the wallet has been unlocked. You can back it up whenever you want and that backup will be valid for 1000 transactions. The general consensus is to back it up every 100/1000 transaction since your addresses will definitely be used up by then. Do you know in which version they changed it? Recently I tested a few altcoin wallets and the daemon always states something like generating address 1 .. 100. So, OP, just be careful and backup the wallet file from time to time. |

If you then encrypt your wallet, the reserved addresses are flushed and new ones will be generated. So it's important that you backup your wallet again after you have encrypted it! Otherwise you don't have your private keys from newly generated addresses.
