That is what Andreas is trying to convey. He is saying that the traditional way of generating random private keys for each transaction in order to prevent address reuse is a poor choice of wallet principle. That is because every time you generate a new random private key, you would have to make sure to keep a backup of it so that you can recover bitcoins ...

This will be mostly possible in the upcoming Bitcoin Core 0.18 release. First you need to understand that the sequence of such paired multisig addresses (with public keys generated from 2 xpubs in lockstep) can be described in the new descriptor language. The syntax is sh(multi(2,XPUB/*,XPUB/*)). The sh indicates P2SH embedding, multi refers to multisig, ...

See Why the Large Bitcoin Collider poses no threat to Bitcoin which explains some of the mathematics involved in an accessible way (perhaps overly so). It gives an example of taking over the whole bitcoin network worldwide and spending $75 million on electricity every 3.5 days but taking 2,250,000,000,000,000 years to find one private key associated with ...

LBC exhaustively searches a relatively small area in the 256 bit private key space. It's not a general wallet cracker, broken or otherwise; rather, it will find a private key that is known to be in the vicinity of its searches. One example that sits in the blockchain is the so-called puzzle transaction, which was created to deliberately reward people who ...

You are attempting to withdraw an altcoin to a Bitcoin address. You need to withdraw to a ‘Vibrate’ wallet, not a Bitcoin wallet.

Simply, they don’t support the same addressing schemes. They use a modified version of bech32 that is incompatible.

Try double quoting lockunspent false '[{"\"txid\"":"\"c3fa34606ae3ea416ff640d97414ef6a0a8afcebfbe2c60403ad60c0d961f04c\"","\"vout\"":"0"}]'

Hardware wallets are preferred to hot wallets and cold storage, as they cannot connect to the Internet, and do not require key input into a computer in order to sign transactions. The second point is important, but also partially wrong. The hardware wallet itself is a computer with very specific set tasks, mainly, key pair/seed generation and transaction ...

You can’t. Bitcoin does not work by names, emails, or material things of that nature. Bitcoin works in an anonymous way where public keys are the names and private keys the persons. There is no way to figure out what you are asking, At all.

How to check the balance of each address or how we can look for balance? You will have to scan the blockchain and find the UTXOs that are locked with your addresses in the locking script. You can either do that by running a full node by downloading and verifying the blockchain yourself, or run a Simplified Payment Verification (SPV) node and query other ...
