VeraCrypt is best option, but if you're linux user, you can use built-in encryption option (LUKS or LUKS2) If you’re using Windows 10 pro or enterprise, you can use Bitlocker which comes with the system.
I wouldn't trust BitLocker since AFAIK it's closed source and has been cracked few times previously. |

It's unnecessary and would create more than problem than it resolves.
If the main goal is to stop signature campaign spammer, then i have another idea such as :
1. Signature limitation based on your merit amount, not your rank
2. Signature only enabled for those who earned x amount of merit within y last month

Regardless what other people said, being open-source or partially open-source should be important aspect when looking for Bitcoin wallet.
People should remember than Bitcoin and most P2P protocol (Tor, BitTorrent, BitTorrent's DHT etc.) only able to success because they are open-source.

we're talking about BitCore I assumed that was a typo, otherwise this thread should be moved to the Altcoins board. While there's cryptocurrency called BitCore, there's a Bitcoin full node client called BitCore ( https://bitcore.io/). Unless OP explicitly he's talking about BitCore cryptocurrency, then this thread belongs to this section. |

I don't think USB drives can help to store (not enough GB capacity) the whole blockchain database after I sync my wallet today.
USB is just the interface. He could mean USB HDD drives which is cheaper than USB flash drive or USB SSD drive. By the time the blockchain reached 400GB, a 1TB HDD would be less than $20, in fact, you can get some 2nd-hand units in that price range today.
I wouldn't recommend using 2nd-hand or refurbished HDD for intensive tasks (e.g. running full node client). |

It is however very hard to really lose BTC because of that issue, because there is always the option of rebroadcasting it, as others pointed out. Even if a seller of a (virtual) good is naive enough to accept an 1-conf transaction, sends the virtual good to the buyer, and the block including it becomes orphaned, then the sender wouldn't be able to scam the receiver as long as the receiver of the transaction is using a full-fledged Bitcoin client (even Electrum should be enough) - because if he simply rebroadcasts the transaction he received it will be eventually confirmed.
True, but it requires the receiver to rebroadcast the transaction. The potential problems are : 1. The seller isn't aware about orphan block (unless the seller regularly check his/her bitcoin wallet) 2. If the seller don't "save" the raw transaction, it's not easy to find the raw transaction in order to rebroadcast it. |

Without proper security audit, i would assume it's only as secure as other bitcoin wallet and i would say it's not worth if you compare it with more known hardware wallet such as Ledger Nano or Trezor.
Running full node is ridiculous (for now), due to high storage usage & broadcast/receive all transaction and block. Running a full node from your home or VPS and connect to it from your smartphone is more sensible option.
TLDR : No, it's only smartphone with wallet/full node application.

he only way I could ever see it being secure is if they don't actually allow customers to withdraw cryptocurrency directly, which would make it almost useless. The banks would then have full control over how, where and when you can spend those funds. That would only bolster the argument about how you need to be in control of your own funds to see any tangible benefits.
Your statement reminds me about this news : Mastercard Wins Patent for “Managing Fractional Reserves of Blockchain Currency”Now they join us
I doubt this about this part. Custodial wallet/storage defeats the purpose of Bitcoin, it's no different from storing your fiat or goods (e.g. gold, jewelry) to banks. |

There's nothing much to say about block,
1. It stores some transaction and smart-contract execution (for cryptocurrency with smart-contract)
2. A block always metadata such as previous block, timestamp and consensus (PoW, PoS, etc.) information (depending on the cryptocurrency)
3. Usually it has fixed maximum size
P.S. You should specify your question to get good answer

But the smart contract platforms people talk about make escrow smart contracts just easy to use, safe, simple. IF the scripts you just shared are so easy to use (they're not for me), why isn't it brought up to be used more often in the p2p trades this forum sees every day? We're still heavily reliant on hiring forum escrowers for big trades.
pooya87's script is about 2-of-3 multi signature address and you already can use it easily (without need to know about scripting) by using wallet which support multi signature wallet such as Electrum. And obviously hiring escrow is still needed. |

Looking at past news, HodHodl was the first exchange which support LN.
I wonder how may people will use LN to deposit their Bitcoin since LN is intended for micro-transaction which need fast confirmation time.

The fresh electrum wallet shows no value. I looked around and just under the tab "adresses" it shows 2 BTC adresses (not the ones I had on Core) with a green marker.
Now Im confused. I think maybe wait a bit time, but after a few hours I don't know if something is wrong.
Try to import your private key again, but with prefix "p2wpkh-p2sh:" (for Bitcoin address with prefix 3), "p2wpkh:" (for Bitcoin address with prefix bc1) or "p2pkh:" (for Bitcoin address with prefix 1) instead. p2wpkh-p2sh:<your private key>
p2wpkh:<your private key>
p2pkh:<your private key>

Unfortunately... People like centralized systems,-- they have lots of nice usability properties, people are willing to ignore their flaws/risks, they are easy to develop, and *critically* they are easy to monetize.
unfortunately, I think you are clueless, you need to understand that most people still haven't discovered decentralized technology, some people only heard of bitcoin and second of all the decentralized technology needs improvement, faster, ect. I disagree. Many people who've discovered Decentralized technology (Bitcoin, BitTorrent, IPFS, etc.) still prefer centralized technology. It's been proven by : 1. how many people store their Bitcoin on custodial wallet or exchange (which isn't intended to store Bitcoin) 2. low volume of DEX |

Jika khawatir dengan Keylogger dan fitur lainnya yang mungkin mengambil data pribadi anda, lebih baik berhenti menggunakan Windows 10 dan menggunakan OS lain seperti Mac OS X ataupun GNU/Linux. Meskipun semua fitur tersebut dinonaktifkan, Windows 10 tetap mengirim data pribadi anda [1]Sumber : 1. https://thehackernews.com/2016/02/microsoft-windows10-privacy.html |

Open Port 8333 is only necessary if you plan to contribute to Bitcoin Network or actually running a full node.

Personally, i recommend https://bisq.network/. They also have bitcoin-to-fiat (and vice-versa), even though it comes with many risks. There are many decentralized exchanges but some of them become a scam.
Or centralized exchange pretend to be decentralized exchange |

Feel free to offer your advice how to best go about doing this.
Don't update your Ledger firmware to version 1.6.0, i was about to update mine  IMO people should make sure they've made backup of their mnemonic/recovery phrase before risking update to version 1.6.0, even if i doubt the storage will be corrupted or wiped out. |

There is a funny circular reference here, as the joke-chart is actually the first chart in the link you provided, that is the same link I linked in my post where I first posted the chart...
I know and i intentionally use same link as source  Which brings us to the next debate, does your app/company need to work through the costly inefficiencies to achieve censorship-resistance?
The chart is only one of example chart, blockchain application isn't limited for an application or company. DEX and Casino on blockchain (with smart-contract help) are the prime example which need to be censorship-resistant. |
