Here is what the gas price was set at. I think it is way too low. It's actually the other way around.
Gas Limit: 7592488 Gas Used By Txn: Pending Gas Price: 0.000000002 Ether (2 Gwei) Max Txn Cost/Fee: 0.015184976 Ether ($10.38) Nonce: 2
As you can see, the gas limit of the transaction is 7,592,488, while the current block gas limit is ~8,000,000 gasBlocks in ethereum have a block gas limit, which determines how many transactions can fit in a block, similar to the block size limit in bitcoin. Your transaction has a very high gas limit so if it is included in a block, there wouldn't be space for other pricier transactions. So your transaction would most likely not be mined any time soon. However, in ethereum, you can "replace" pending transactions by broadcasting a transaction with the same nonce but with a higher gas price. To do that you'll need MyEtherWallet. Go to MEW website, to the offline transactions tab, in the field for the "from" address, insert your address, in the destination address insert any random ethereum Address. In the amount to be sent, input 0 eth. Set gas limit as 21,000 or 30,000. Set gas price according to ethgasstation.info (3 gwei should do the trick) note that the price is in Wei, so 3 gwei = 3000000000 Wei (9 zeroes after 3) In the nonce field insert the same nonce as the pending transaction which is 2. Then import your private key, sign the transaction and broadcast it. This new transaction will override the pending one and you can now resend it with the correct gas limit this time. |

I don't mean to be rude. It's not me, but you who aren't listening. I don't need somebody's money. I'm trying to recover my funds. Even though everybody tells me that it's not possible. I've read about folks from LBC or BLC or whatever it is...has nothing to do with me or my goals. I would be gratefull to anybody who has something to say about a working script, besides the prognosis with possibilities rates.
Okay, I'm sorry if I was harsh earlier. The thing is lots of people come here thinking they can magically generate addresses that already have Bitcoins, neglecting the fact that it bitcoin's security model was so easily broken then no one would use it at all and it wouldn't have any value.
That aside, for what you want to work, you'll need most parts of your private key or mnemonic seed phrase, then the search space would be reduced exponentially and you wouldn't have to do as much work. However, if you do not have anything apart from the address, then there's nothing you can do because trying to generate YOUR Address is as hard as trying to generate any specific address (even those of exchanges with billions of dollars worth) and as you can see that is pretty much impossible even though you have all the computing power in the world. So you need something to work with apart from the bitcoin addresses or you're SOL. That's the way crypto is. |

Thnx. Heared about that soft. Thought about command line on it. How to run it as loop (to constantly create address/key pairs) and compare addresses from these generated pairs to my BTC adresses (saved in .txt or whatever) automatically and possibly keep logs of it? I've seen something like that already, just wasn't able to find it.
PS. So that my grandson could discover one day his grandpas-old-medicine-shit-laptop in the basement and feel happy about it))
Since you do not want to listen that it's futile, whenever you find a brute force software, try to generate the private key for any address in this listMaybe in a few million years when you discover you haven't made any headway, you'll finally realise that it's futile |

Lots of crypto wallets -- especially mobile ones-- notify the user that they have received funds in an address they control.

The windows wallet: https://electroncash.org/I tried both downloads, ElectronCash-3.2.exe and Portable Version but neither allow running in testnet unlike Electrum which installs the testnet option in windows start menu Since Electron cash is a fork of Electrum, the --testnet argument should work also. Read this post for details |

@Xynerise thank you for the explanation, it makes sense now.
Would you know how run the desktop wallet in testnet mode?
For what wallet? Electron cash or Bitcoin ABC? Both should work the same way as their Bitcoin counterparts. |

Thank you for the reply. My desktop wallet is the latest Bitcoin Cash/Electron-Cash v3.2 and I also have v3.2 running on my Digital Ocean Ubuntu server. When I view addresses on the desktop I see "1" but on the server they are "Q".
Please advise which is the wallet that needs updating, the desktop one which already has "1" prefix or the Ubuntu server one which shows "Q" prefix? Since both are running v3.2 please advise how I am supposed to update the one that needs updating
3.2 is the latest version of electron cash. It already supports cashaddr format. Click the blue button on the bottom right corner of the screen near the settings icon as shown below  If the blue icon is on it will show receiving addresses in the Bech32 format; if it's off it will show addresses in the legacy base58 format. |

When I used the MPK to add to Ubuntu Digital Ocean all addresses on the server start incorrectly with: "Q" prefix It's not incorrect. Addresses that start with "q" are Bech32 addresses, similar to bc1 addresses in bitcoin. It was introduced to differentiate BCash addresses from legacy bitcoin addresses. They're equivalent to legacy addresses that start with "1" as they have the same private keys. When I use testnet faucet I can receive BCH on "1" prefix addresses but when I use "Q" prefix addresses the transaction fails
Bech32 addresses are a new address format and as such aren't backwards compatible. Wallet software must be updated to support the new address type. You can use an address translator, such as this to Convert from Bech32 to legacy format |

thanks for the answer, can I use the instructions to insert the key?
Yes you can. Remember not to give anyone your private key or else they'll be able to spend your Litecoins |

Okay, now I understand. You sent LTC to an address generated from a bitcoin wallet (bitcoin Address) Litecoin and bitcoin have the same address scheme so the transaction went through. You say you can cancel it using a key, that should be the private key. (It should start with 5, K or L) Download Electrum-LTC from here: https://electrum-ltc.orgInstall it, then you can import the private key for the bitcoin Address starting with 3 into it and access your Litecoins. When you install Electrum-LTC, open it, when it asks what kind of wallet you want to create select "import Litecoin Address or private keys" and click next Then paste your private key into the field that appears and select next Then the address starting with 3 should show, and you can now spend your Litecoin. |

I sent a coin to this address 3H6RQQthC5HV1BUYT38NpF9CJVgJzVkubp, I have a key from this address, but I do not know what to do with it and how to cancel the transfer
Where did you get the address from? A bitcoin or Litecoin wallet? Is it your address? You cannot cancel cryptocurrency transactions. |

You get a option to pay a new fee, by clicking the lightning symbol in the ledger wallet.
That initiates a child-pays-for-parent transaction in which a new transaction is made spending the change outputs from the unconfirmed transaction but witha higher fee for both transactions so they get confirmed together. But when i'm asked to confirm the transaction on my Nano s, its not the same address as i sent it to, and the amount is not the same. Yes, that's how CPFP works. Let's say you sent 0.3 BTC to an address with a 1 BTC input, so you have a ~0.7BTC change output also. If you used a too-low fee for the transaction then you can spend that 0.7BTC change to another address that you control with a higher fee so that your 0.3 BTC transaction confirms and the new child transaction confirms at the same time. When you click the lightning bolt icon, the Ledger wallet does this automatically for you. Are the BTC on the new transaction just paying for the fee, and is it supposed to go to another address?
Exactly, yes, as I explained above. That new address is still controlled by your Ledger. You can connect the Ledger device to Electrum and confirm that that address is part of your receiving addresses.
If you don't wish to pay more fees to accelerate your transaction via CPFP, then you can just paste your transaction ID in Antpool's transaction acceleration service And it will be included in any new block they mine. This service is free, but you'll have to sign up on their website. |

Ok...I was supposedly paid by someone and they sent bitcoin to my blockchain account. The dollar amount shows up, but I cant send, transfer or spend any of them. It is an imported account and it says I need the private key. How do I get that? I will pay the first person who helps me .5 bitcoin.

You were most likely scammed. That's a watch only address. You imported an Address, not a private key. Anyone can import a bitcoin ADDRESS to watch the "balance" and transactions of the address, but unless you have the private key to that address, you can't spend from it. So if the person gave you just a bitcoin address to import then he scammed you. For example, this is Bitfinex's cold wallet Address: 3D2oetdNuZUqQHPJmcMDDHYoqkyNVsFk9r It contains billions of dollars worth of bitcoin, everyone can see the amount and transactions, but only Bitfinex can spend from it because only they have the private key. You can import that Address into your blockchain.info wallet to WATCH the address, but that DOES NOT mean you can spend from it. |

. If the price of bitcoin indeed goes up, it is not so difficult to see how the entire network could run just on transaction fees, despite the projected halving of the block reward.
Fun fact: around Christmas of last year block transaction fees were higher than the block reward which suggests that the network can be secured on transaction fees alone as Greg Maxwell noted |

what about the btc after it no btc to mining?
there will no miners and how to keep the net active?
Miners will be rewarded with transaction fees only when that happens. |

It's an invalid script why is this not rejected in the first place?
It's not invalid, but nonstandard (even though it may not have been deliberate) (The script itself is invalid, but the transaction as a whole is valid because it obeys bitcoin protocol rules. It's possible to have an invalid script but a valid transaction eg this one, and a valid script but an invalid transaction eg one whose input has been included in the blockchain) Invalid means that it tries to break bitcoin protocol rules in some way (eg double spending, if the script stack returns false, creating more outputs than inputs --1 BTC input creating 5BTC output for example , etc) As long as it doesn't conflict with transaction protocol rules then it's "valid" Nonstandard transactions are the ones that don't follow the script templates of the reference software eg P2PKH, P2SH, etc. Nonstandard transactions can be included in a block (as long as they follow the rules), but invalid transactions cannot be included in a block. For example, this transaction spending 0.02BTC is nonstandard, but not invalid, even though it's outputs can't be redeemed. |

Usually, when you import a segwit private key from Bitcoin Core to Electrum, Electrum generates a legacy address (starting with '1') instead of a Segwit address (starting with '3' or 'bc1') because Bitcoin Core uses the WIF for all address types while Electrum has a custom WIF for different types of addresses so each WIF corresponds to 1 bitcoin address. Also, because of this, you're also unable to import a segwit WIF from Electrum into Bitcoin Core because Core doesn't understand the custom WIF. However, Electrum internally maintains backwards compatibility so you can convert an Electrum custom WIF to one Core understands.
How To Convert An Electrum segwit WIF to standard WIFFor P2SH-P2WPKH addresses: Open the console in Electrum and type the following code . (Press enter after each line) key = 'L4wAtJ8RYaxtRYZxUwZRH8qGYVv1LUP3RAh9ER9KK2HeTXW6v4Ru'
txin_type, secret, compressed = bitcoin.deserialize_privkey(key)
wif2 = bitcoin.serialize_privkey(secret, compressed, 'p2wpkh-p2sh')
print(wif2) Replace "L4..." with the private key you got from Electrum and leave the quotation marks as is. It should print a WIF that you can import into Bitcoin Core. For P2WPKH addresses (Bech32)Type the following code, replacing the private key there with yours. key = 'LAst2SKVNx36PUY2q49cyLCcpze1YMvdJ66z3uKuiyaLKTVVsH3J'
txin_type, secret, compressed = bitcoin.deserialize_privkey(key)
wif2 = bitcoin.serialize_privkey(secret, compressed, 'p2pkh')
print(wif2) It should print a private key you can import into Bitcoin Core to get your Bech32 address.
How To Import Segwit WIF from Bitcoin Core to Electrum This one is simple to do. NB: For this to work you need to be on Electrum version 3.1.1 and aboveFor P2SH-P2WPKH addresses (Addresses starting with "3")Just add p2wpkh-p2sh: directly in front of your private key. For example p2wpkh-p2sh:5BitcoinPrivateKey This should generate the corresponding p2wpkh-p2sh bitcoin address. For P2WPKH addresses (Bech32, starting with 'bc1')This time we'll add p2wpkh: in front of the private key. For example This should generate the corresponding Bech32 address |

what a waste!! a full block reward of 12.5 BTC evaporate into thin air  are they doing it intentionally? or was it caused by accidental faulty script running on their nodes? This one looks like the miner's mistake, he might have entered an invalid bitcoin address in his mining console or configuration.
Who knows. The Output script of the transaction is 52534b424c4f434b3addbf517adf8ffd4bca7751505b39c9013a0d1fd479fc4e901b39dd57b347c624 which, when converted to ASCII gives RSKBLOCK:ݿQzߏKwQP[9:
yN9WG$ so it may have something to do with the Rsk.co sidechain |

The rule states that it can't be MORE than the current block subsidy, but it can certainly be less. For example this Coinbase transaction has an output of 0, while this one is 0.01 BTC less than the block reward In cases like this the bitcoins are lost forever. |
