I asked that do we need to set a slab (for e.g.: if we need to take in transactions with fees not less than 200 sats/byte and not more than 600 sats/byte, do we need to (or can we) put it like 200 - 600 sats/byte transactions to include transactions within the mentioned slab only)?
Yes, you can include any transaction you want into your block. A lot of people seem to not understand how a block is generated. Its not like you 'mine a block' and afterwards include your transactions into it. I would suggest to read https://en.bitcoin.it/wiki/Block_hashing_algorithm and https://en.wikipedia.org/wiki/Merkle_tree. As well, if this is the case and we are allowed to choose our own size of transaction according to the protocol and decide not to include those low-fee/byte transactions, will they ever confirm?
If those low-fee/byte transaction will never be mined, they never will confirm. Its fully dependend IF and WHEN a miner decides to include this transaction into his block. Im not sure what you exactly mean with 'we are allowed to choose our own size of transaction'. Transactions can be up to 100kb in size (to be valid according to the network rules). |

Did you nano generate the same addresses (resp. the same first address) after resetting it with the 24 word seed phrase? If yes, then its probably just a display error or a network issue with their online service. If, somehow, the address generated by your nano s after resetting is not one of your addresses and is unused then the seed most certainly doesn't match your old seed. You could look into 'Settings' -> 'Tools' -> 'Sign message' and check the 'Address'-drop down menu and watch out for one of your addresses. If it's contained, then everything is fine and its probably a display/network issue. But if you don't find your addresses and it seems like a 'fresh wallet', you can still import your 24 word seed into another BIP39 compatible wallet (e.g. electrum[1]). Make sure to choose the right derivation path: m/44'/0'/0'/ when restoring your seed in a wallet different than ledgers native one. [1] https://electrum.org/#home |

How did you withdraw your verge without having any address to send them to? You have to 1) download verge wallet 2) create a new seed/wallet 3) get your address and withdraw/exchange your coins to it. Its quite strange that you already exchanged your eth for verge without even owning a wallet / an address. Did your output go to an address starting with D.. ? Verge addresses start with D, where BTC's addresses start with 1, 3 or bc1. You can get the electrum client for verge here: https://vergecurrency.com/langs/en/ |

As already mentioned, the transaction seems to be dropped from almost all mempools. I tried to push your raw transaction, some sites gave an error when doing so (min mempool fee not reached). You might try a few more online services to broadcast your transaction or use core and broadcast it 'manually'. Your can broadcast your transaction in hex format: 0200000014f2bda5db02d98978d19348e5a80fcd587feb6877deba16e4882b19f1738a7da41b0000006b483045022100f6ea88c9ba9c12a38919042a5e88126ed7df3d61b820900c37b6875

If you were the recieving part of this transaction you should contact the person who sent this TX. Only regard transactions as completed when they at least recieved 1 confirmation. Additionally you could contact a miner and ask them to include your transaction into their block (as long as its not conflicting with other transactions). This will most likely cost an appropriate fee. |

Payments should only be regarded as completed when the TX at least recieved 1 confirmation. What happens if I just wait? Will the transaction go through sometime in the future?
This depends on the fee paid and if the transaction is going to be rebroadcasted after being unconfirmed for several days/weeks. You could look the transaction up in this blockexplorer: https://blockchain.info/ and add ?format=hex at the end of the URL afterwards. Then copy the hex transaction. Afterwards you can try to broadcast/push this TX into the network when it has been dropped (if this is going to happen at all). To push the TX after it has been dropped you can either use core or an online service[1].

With the lightning network, if I want to send say 1 bitcoin to someone I have never met and don't know, how will that work in practice? Will we have to first set up a channel between us and deposit bitcoin in it?  The lightning network is an implementation of Hashed Timelock Contracts ( https://en.bitcoin.it/wiki/Hashed_Timelock_Contracts). You can think of it as a network with bidirectional payment channels which allows the payments to broadcasted/routed between several channels safely. Therefore you and your business parther would not have to join the same channel since you are connected through a 'network of paymentchannels'. |

Why does not it apply to bitcoin? Sooner or later you submit transaction and your public key is revealed.
Yes, but i was refering to the possible threat of IOTA, lisk,.. when storing coins on an address which already has been spent from. This does not apply to bitcoin. I get you private key with quantum computer ...
1) No, that doesn't work like this. Quantum computer because: a) They dont even exist yet because the whole superposition states are unstable yet and the error rate is way too high. b) There are a lot of resarches done breaking RSA (prime factorization) with quantum alogrithms, but no researches are done about how to break elliptic curve multiplication. 2) Bitcoin is quantum resistant 'by design'. Until you spend from an address the public key is not known and therefore its not possible to attempt to crack the ECDSA ( https://de.wikipedia.org/wiki/Elliptic_Curve_DSA). If ECDSA will get crackable (which takes a quite long timespan; this doesnt happen over night): i) there still will be forks (probably consensus) to prevent BTC from being crackable, and ii) this would put BTC at the same 'security level' as IOTA, since until your public key is known, such an attempted attack is not possible. |

.. I am storing my coins in unspent address but it creates address collision risk ..
.. There is no benefit in security by spending your coins from an address. Address collision risk is equal whether your public key was published or wasn't before .. Is it valid for Lisk? because they suggest spending to avoid address collision risk The reason for Lisk, IOTA, etc.. being unsecured when laying on an address which already was spent from is because the whole network gets to know the public key. This public key then can be used to 'crack' the private key (considering the algorithm makes it possible). This applies to iota, lisk, ... but does not apply to BTC. But this has nothing to do with address collision. Address collision is a term to describe the phenomenon of 2 people randomly generating the same priv-/public- keypair. |

Bitcoin is currently able to handle about 3 Transactions per second.
Now bitcoin cash doubled the block size.. so about 6 tx / s are possibe..
Thats a pretty weak 'technological' growth. Increasing block size is just delaying the problem. Its not solving it at all.
The lightning network (together with segwit) on the other hand could have the capacity to handle up to 50.000 Tx/s.
This brings bitcoin to the same level of scalability as ripple, which is quite impressive.
IMO BCH is just a fraud. It may take some time.. but people will realize that BCH is just a smart way of stealing peoples money.
In the end BTC will outpace BCH in terms of everything.

Do you have a 12-/18-/24- word seed backup? Or can you export the private keys of your addresses? If so, you can import them into another wallet (e.g. electrum: https://electrum.org/#home). You will be able to adjust the fee as you wish, but low fees lead to low (to no) confirmation time. Currently there are 280k+ unconfirmed transactions waiting to get confirmed. The only way to send your coins cheaply is to send a low-fee-TX and wait for it to get confirmed. To get an estimated time interval until your fee will probably get confirmed, you can visit: https://bitcoinfees.earn.com/ |

You DO now that Bitcoin and Bitcoin Cash are two completely different currencies, right? You can't send BTC to a BCH address and vice versa... you have exchange your BTC on a marketplace for BCH... Now.. to get access to your wrongly sent BTC you can export the private keys of your recieving-BCH-address and import it into another BTC wallet. You will be able to spend them from there on. There are quite a few tutorials online to export your keys from JAXX and to import them keys into another wallet, just google it. BTC and BCH are different networks/blockchains. If you sent BTC to a BCH address (or the other way around), it's lost forever.
Nonsense. Same private-/public- keypairs, same transaction history until block 4xx.xxx. Of course you can recover wrongly sent BTC's, with easily importing the BCH private key into your BTC wallet... |

This seems pretty fakeish to me. Didn't found any reputable sources about those statements made. Also, if cryptocurrency transactions are anonymous they have no power to forbid this...
Thats the point. There is no possible way to force customer/cryptoenthusiast to reveal their transaction history with all of those upcoming and right now trending private coins (e.g. monero, verge, dash, ..). Once it gets to this point where the control of the government gets that extreme, most of us will have adopted to a privacy coin. They have the right to forbid this.. but they won't have the capabilities to execute their ban. And even considering exchanges, there is localbitcoins and there will be more if there is more demand for 'privacy related' marketplaces |

Your nano s can't 'take some time' since it's not taking any active part when recieving a transaction. The nano s is just a device to store your private keys (which are used to sign transactions (send coins)). The time it takes for your transaction to show up on your ledger app usually takes a few seconds. The transaction, after being sent, will be broadcasted and forwared to every node. After ledgers node recieved the TX it will show up in your wallet. The time until a transaction gets confirmed is fully dependend on when a miner includes your transaction into his block. To get your transaction confirmed pretty fast you have to either 1) be/know/contact a miner who includes your TX or 2) pay a fee which is attractive enough for any miner to include your TX. It doesn't matter which amount of BTC you are trying to transfer. It is depending on the fee, not size. When withdrawing from coinbase you have no control over the fee set. You can look the transaction up in a blockexplorer [1] to check the fee. Afterwards you can go to https://bitcoinfees.earn.com/ to check the current status of the backlog of transactions waiting to get confirmed. You can find an estimated waiting time for your tx. [1] e.g. https://blockchain.info/, https://www.blocktrail.com/BTC or https://bitcoinchain.com/block_explorer |

Its not necessary to withdraw them to a legacy address. To withdraw litecoin from coinbase to a segwit address you have 2 options. 1) You can transfer your funds from coinbase to GDAX (which is free of charge) and cash them out there, since they allow segwit withdrawals. 2) You can use a P2SH converter (e.g. https://litecoin-project.github.io/p2sh-convert/) to convert it to a coinbase-accepted-format. I would still be a bit careful when using the second method. To be on the safe side, test it first with small amounts. |

This is the only way to extract your private keys out of your seed. The tool itself is used quite often. No complaints so far. Of course you should boot from a linux-bootabel device and use this tool offline. If your still not feeling safe (which is quite reasonable, since a HW wallet is designed to never expose private keys) you can create a new wallet, send your coins onto that and then export your private keys to fork your (probably worthless) altcoins. Which fork? Ledger has created apps for BCH and BTG so you can get your coins using the Ledger wallet.
There is no need to export private keys.
He is probably trying to get the unknown (and worthless) forked coins like btc diamond, etc.. |

What do you recommend me to do?
The first thing you should do is to create several backups. Do not try any recovery on the original file. Use copies for that. You can try to extract your private keys out of your wallet.dat using any recovery tool. You can use pywallet ( https://github.com/jackjack-jj/pywallet) for example. The command needed to be run is ./pywallet --wallet=wallet.dat --datadir=/path/to/folder_with_wallet.dat --dumpwalletFor more detailed instructions visit the github repository (link posted above). |

Mostly like you would remove any other application from linux. - apt-get remove package will remove the binaries. Configuration / dependencies will not be removed. - apt-get purge package will remove everything regarding the package (except for dependencies). To remove dependencies apt-get autoremove has to be executed afterwards. To completely remove any traces of electrum at all you can overwrite the file several times to make it unrecoverable. You can read more about unrecoverably deleting here: https://www.tecmint.com/permanently-and-securely-delete-files-directories-linux/ |

heralded has a way to defeat the banks big rip off business, etc, with their high fees
Bitcoin follows the philosphy of all business, get people in with introductary offers of fees in the pennies or even nothing, and then WHACK, RIP EM OFF
The joke is the fees are even higher now than the despised banks.
Anyone who thinks the miners are going back to penny fees are deluded, no way will they give up their 20 dollar fees ....EVER
From your post its pretty clear you don't understand how the whole system works. Miners dont have to give up on the 'high fees'. With segwit the median transaction is cheaper, but miner still earn the same. In addition to that the extreme 'rise of the fees' comes from the BTC value rising up so high. The satoshi amount didn't increase that much - just the countervalue. Please first read yourself into the functionality of bitcoin and the problems/solutions included before making posts which don't make sense. A shift from the every-day currency to a store of value has been visible for quite a few months. |

In time yes, look in to the lightning network that is being developed, it should lower fees and increase transaction speeds. In the nearer future it looks like segwit2x may go ahead again, increasing block sizes should in theory increase speeds.
When the lightning network gets implemented you won't need to bigger the block size. Segwit isn't even fully adopted yet. If everyone would use segwit, the transaction fees would be way lower. Actually segwit is enough scaling until LN get implemented. On-chain scaling like doubling block size is just a short-term solution. A second layer (e.g. lightning network) are the way to go and make block size increase needless. |

Alright it seems like core didn't broadcast your transaction properly. To broadcast them by yourself you can do the following: - Open 'Help' -> 'Debug Window' -> 'Console'
- type getrawtransaction <yourtxid>
- type sendrawtransaction <output_from_above> to broadcast it
(without the '<' '>') If this still doesn't work you could use one of the following sites to broadcast your transaction(s): |
