More specific, the part "Remote Procedure Calls (RPCs)"... There are also other options, like running bitcore: https://bitcore.io/guides/wallet-service/This being said: i never recommand anybody to start using a web wallet, starting a wallet service as a novice user without any trust is a bad idear (IMHO) |

I will not use it because it will kill your phone, use pc if intend to mining, the results you can not match your phone's life
not useful if using too many scam phones hanging around
Fixed that for you... We're not in the altcoin subforum, so we're talking about BITCOIN mining. At current diff, mining BTC with your PC is a very, very, very bad idear. Proof: https://www.mocacinno.com/nonspecialisedmininghardware.php |

There are many wallet for crypto,
Such as-
Electrum,
Mycelium,
Jaxx,
Blockchain,
Exodus
and Coinbase for simple & easier wallet.
I like Electrum wallet. It is more secure, you can also use this wallet. Or if you a beginner then only Transactions wallet is coinbase better.
Can you give me best BTC wallet? I know coinbase better for a beginner but huge all transaction fees... so I ignore Coinbase , you can say how can I do? Thanks for advance. which one is best bitcoin wallet its depends on your demand and uses.if you want to hold your coin than you need to hold your coin into paper wallet or hardware wallet.if you want to do daily transaction you can use blockchain wallet. here you can found good bitcoin wallet https://bitcoin.org/I wouldn't recommand an online wallet, not even for daily transactions. If you want to do daily transactions and own a lot of BTC, i'd recommand a hardware wallet. If you don't own a lot of BTC, a desktop wallet on a clean PC will probably suffice. The only reason for using an online wallet (imho) is when you're travelling, and you need access to a small amount of BTC from anywhere in the world... Even then, i'd probably use an encrypted mobile wallet instead. |

Sorry guys to disappoint you but I'm still mining with my Lumia 1020. Yeah I know it's sounds crazy but I'm doing this since November last year. It is just for fun, not real profit. In the begging was like around 8000 satoshi every week, then started to make 5000 every 2 weeks now its more like 5000 in 3-4 weeks. Till now I have mined approx 80 000 Satoshi. The phone is at work so no bills for electricity. Here is the proof :  The image shows you're creating SCRYPT hashes, bitcoin's POW algo is SHA256D, so whatever is happening, you're not mining bitcoin with your phone. IF, for example you're mining Litcoin with that phone, this calculator tells me that at current diff, you should be mining around 21 litoshi's/day... That's ~600 litoshi's/month... Still far from the 5000 satoshi's you say you mine... This leads me to belief that the software is either mining an even lower diff coin but mislabeling it as bitcoin, or it's doing something completely different (like showing you adds, or mining even another coin with a mobile friendlyer POW algo, if such a thing even exists), or you *might* be looking at your stats wrong... Several years ago, when the diff was many factors lower than it is today, 5000 sat/week was a possibility, maybe you're looking at historic stats? |

Hello guys. I start to earn money via HashCoin Site: https://hashcoin.hostWho thinks about this service? I already output about 0.01BTC  What do i think about this service: It looks exactly like all the other ponzi scams out there... I wouldn't invest a single satoshi there, nor would i ever recommand anybody to invest their hard earned funds on a ponzi... There is no 100% proof, but the modus operandi is exactly the same as all the other ponzi's, as are the other telltale signs like the hidden whois info, the new domain, the used template, the unrealistic profit expectation, the refferal program,... |

Previously I apologize if I am wrong place to ask this.
I have a computer with game specs, with 8gb of ram. But I do not understand about hardware. I want to try to mining bitcoin or altcoins. Is it possible that I could benefit if I just mining through software or application mining and not use added hardware?
I really want to mining crypto, but I do not know where to start, is there anybody can tell me?
Thank you before.
Bitcoin mining = no, you can't make any profit whatsoever unless you invest in a latest gen asic and have a good plan and electricity rate. Altcoin mining = maybe... If you have a decent GPU you can potentially mine some altcoins, however, if you want more info, you should ask your question in the altcoin mining subforum Good luck Well that is my problem, I do not know about the hardware and anything to be prepared to start mining. Is there any difference between mined bitcoin and altcoins? which one is easier to apply to a beginner miner like me? Mining bitcoin or altcoins? Thank you for responding to my thread. Easyer? When talking about altcoin mining with a GPU and bitcoin mining with an ASIC? Defenately bitcoin mining with a recent ASIC... - Basically, you start by looking for a good price for an S9 + PSU + S&H + import duties... - Next you visit a mining calculator like https://www.coinwarz.com/calculators/bitcoin-mining-calculator- you fill in all the questions on the mining calculator... An S9 hashes at around 13500 Gh/s and draws about 1400 Watt. A default pool fee is ~1%, the price is the price you found for the S9 + PSU + S&H + import duties, the electricity rate is your local electricity rate. - Next you see if the ROI is reasonable. Do realise that if the diff jumps up, the ROI rises, if the BTC/USD price goes down, the ROI rises, if the blocks halve: the ROI rises IF the ROI is reasonable given your power cost and the total price for the ASIC, you can just buy the S9, plug it in, surf to it's web gui, fill in the details you get from your favorite pool and start mining. Altcoin mining, on the other hand, usually requires you to look into which altcoin you want to mine, you'll have to research about your GPU, then setup the mining software on your PC and run it, but constantly keep an eye on the shifting altcoin markets... I don't know a lot about altcoin mining tough, if you have more questions, you should ask them in the altcoin mining subforum. One very important sidenote tough: eventough in my opinion, nothing beats the user experience of just buying an S9, plugging it in and surfing to the web gui, the maintenance and reparation of an S9 is something completely different. IF you burn your GPU, there's a fair chance it's still under guarantee (a lot of those GPU's have 3 years factory warrantee). You can buy a replacement GPU in your local computer shop, and if you're done mining you can get a fair amount of cash for your second hand GPU. An S9 ASIC on the other hand, has only 3 months (very limited) guarantee. It breaks a lot easyer than a decent GPU, and if it does, you're usually in a lot of trouble: you'll have to send boards to china, wait, get your claim rejected,..... Also, when a new (more efficient) ASIC hits the market, the second hand prices for your ASIC will plummet. |

If your new laptop has an SSD, a decent processor (i5-i7) and sufficient RAM, ~24 hours sounds about right... IIRC, somewhere around core version ~0.13, there was some kind of rewrite of some of the sourcecode with a result of a speedup while syncing....
OK, thanks. I never would have imagined that running a full node could be so easy. Craig fakesatoshi Wright vibez! It all depends on the bottlenecks... The io of your disks, the amount of ram, the number of cpu threads, the clockspeed, your internet connection... If you have little or no bottlenecks, the syncing is indeed fast enough... Anyways, if you downloaded bitcoin core from the official repo and checked the signature and you're connected with enough peers, there is little to worry about in the first place |

I just got a new laptop, with plenty of hard drive space, so have started with bitcoin core 15.1, as per the instrutions at https://bitcoin.org/en/full-node#ubuntu-1610. It has only been syncing for about 12 hours and already states that the estimated time left as 22 hours, 5 years and 15 weeks behind. I thought syncing was supposed to take at least a week! It took about 10 days last time I did it 2 years ago. So of course, I'm a wee bit suspicious, and paranoid. DSL speed test: 1.2Mb/s download, 0.5Mb/s upload Running Ubuntu 16.04, with 32G RAM, Intel® Core™ i5-8250U CPU @ 1.60GHz × 8, and a solid state drive. Yes I know that's high spec, but still, thought I should check. Thanks If your new laptop has an SSD, a decent processor (i5-i7) and sufficient RAM, ~24 hours sounds about right...

Most of the coins in your list have a diff that is so high you can only use an ASIC to mine them, the rest are only GPU minable... Could you explain why you think it would be a good idear to browser-cpu-mine a coin like bitcoin? To tell you the truth, doing something like this does not give me a lot of confidence in your enterprise.

There are some apps which use mining on android.
...and you're better off staying away from them. I can assure you they're most likely duds. You also risk getting spyware on your device, which is especially disastrous if you're involved in crypto. Even powerful gaming PCs are barely powerful enough for mining, so there's no way you can mine with a mobile device. You could do something like this though lol: https://motherboard.vice.com/en_us/article/3kvdv9/samsung-upcycling-galaxy-s5-bitcoin-mining-rigYou could have the power efficiency of five whole PCs!!! /s There was an error in your text, it should have been " NOT even powerful gaming PCs are barely powerful enough for mining". I actually wrote a small script for up-to-date info i can use whenever this discussion starts: https://www.mocacinno.com/nonspecialisedmininghardware.phpAt the time of writing, an "AMD ATI 7970" running at 100% load 24/7 will mine ~2600 satoshi's A YEAR. If you have a power rate of 5 cents/Kwu (which is really, really, really, really cheap), you'll pay ~$123 more for your power than you'll make from mining, so basically, mining with a gaming PC will cost you money. |

If i miss the "testnet=1" flag, i'll be running it on the Mainnet ? What do you mean, it's the first line in bitcoin.conf file posted by curiosity81. Since his post was last edited 2 days ago, and your post is less than 1 day ago, the line should have already been there at the time you were creating your post??? |

Is that while Blockchain technology can be replicated without bitcoin purposely, there has to be some kind of token allied with the ledger in order for the system to work. I have no idear what you're trying to ask/tell us. Maybe it would be a good starting point to read up on the lightning network? |
|
|
|

I've been running a c-lightning node on the testnet for a while now...
The reason i chose c-lightning over eclair was that i don't really like running java applications on my sever (i find them slower and more resource intensive than compiled c code) and i like to run a headless server.
Can eclair be run as a daemon, or only as a gui application?

Depending on which operating system you are using you can try to delete blockchain_headers file which is located here : http://docs.electrum.org/en/latest/faq.html and then run Electrum and let it sync.It is possible that some of the files are corrupted since you eliminated a problem with synchronization. Before you do anything be sure to have backup of your wallet files/seed.If deletion of blockchain_headers file does not help,you should try clean install of Electrum which means uninstallation of Electrum and deletion of Electrum folder with all data. One extra remark: stop running 2.9.x on Tails... If you run 2.9.x, you're running a version with a huge bug that can be exploited, even on tails... |

What about a trezor wallet? Does that have this functionality?
I don't have my trezor with me right now, but i'm pretty sure trezor's web wallet doesn't have paytomany functionality either... Same answer as the ledger, basically: use a compatible desktop wallet like electrum, couple it to your trezor, use the pay to many functionality from electrum while signing the transaction on your trezor. EDIT: after reading ranochigo's post, seems like my memory isn't as good as i tought it was |

I believe the first thing that might have triggered an armed robber to attack someone and demand a transfer of their coin is if the armed robber knows that the person been attacked is a bitcoin or crypto trader. This is why it is recommended that you live low key if you are trader especially one with huge fund. iluvbitcoins suggestion is perfect but what if you where not at home when the incident happens and was attacked when you least expect it; probably when you are out for a quick dinner? I guess its better not to have a trading app on your phone and live a low key Life till when you decided not to trade again. Though, most people may not like it since they want to live a five star life when the gains start pouring in.
Keep the cold wallet at home encrypted and only a hot wallet with you, therefore if someone attacks you, if you're forced to, you can give away a low amount of coins. I'm unsure how it works in the US, but if it's possible, get a legal carry, if not, as I said, pepper spray, electric shocker, or a knife.I'll be getting a new batch of bitcoin knives soon, might as well get those  sigh... Some of us live in countries where it's illegal for an individual to carry any kind of firearm (unless traveling from home to a shooting club or back, carrying a legal licence, with the gun locked up in the trunk), any kind of gas pistol, pepper spray, knives, tasers, baseball bats,... Basically, it's illegal to carry anything you can use to protect yourself  Personally, i recently hired a safe at our local bank to store my hardware wallet (+ the encrypted seed). I don't own that much BTC anyways, but i was entertaining the idear of renting a safe to store my house's deed, my testament, some silver coins,... so when BTC price jumped, i just hired a safe and got it over with. |

I have many low-value incoming transactions in my wallet. Some have been spent in outgoing transactions, they have no value anymore. Some are unspent, and represent my bitcoin balance.
I want to know the number of incoming transactions with value required for one outgoing transaction in order to estimate the transaction costs.
How can I detect when a transaction has been spent and has become valueless?
Regards!
Which wallet software are you using? Without knowing this information, it's not really possible to give a conclusive answer to your question. You can always lookup the receiving addresses generated by your wallet on blockchain.info... However, if you used unspent outputs to create a new transaction, it's possible your wallet generated change addresses, so you might have change addresses you did not manually create, but still belonging to your wallet containing unspent outputs. |
