'''
“Simplified Payment Verification (SPV)
One well-known alternative security model is SPV. This model supports verifying payments without requiring access to the entire blockchain in exchange for trusting Proof-of-Work (PoW) and Proof-of-Stake (PoS) miners to verify the history and a stronger non-partitioning assumption. However, this means that if an attacker is able to overpower the network's PoW hash power, it can trick SPV nodes into believing fabricated transactions are valid for as long as the attacker overpowers the network.”
After consensus onchain, Decred now supports one of, if not the, most privacy preserving and secure decentralized lightweight client (SPV) implementations in crypto.”

How to securely split Bitcoin SV from Bitcoin cash in Cash Electron client

There are no SV servers available anymore in the Bitcoin Cash Electron client. I try to stay away installing anything from SV (like the ElectronSV software client).
I'm looking for a secure and replay safe way. Entering my seed phrase/private key as many guides suggesting on an internet connected machine is simply not an option. That's why I use Trezor in the first place.
TREZOR Wiki answered it here. However, that guide is broken. It refers to find SV servers within the Electron Cash client:

Rather inexperienced with Bitcoin but at the same time I accepted some 2 years ago from a client as payment for a remodel. Sounded fun. Now I'm concerned that keeping them on Breadwallet and Copay isn't secure like Coinbase. Advice please. Should I get a hard wallet?

Insurance for a bitcoin exchange

Unsure if anyone else has looked into this yet: I have two ethics advisory questions in to two respective state bar associations (U.S.) about securing client bitcoins in my lawyer trust account. Essentially any item of value my practice takes for future performance is held in a safe if it's personal property or in the bank if it's tangible currency (so that the interest can be generated and paid to indigent legal services). Some lawyer's have tried to generate press by stating they'll accept Bitcoin for present payment that does not get held in trust, others will accept it to trust but give the client an equal USD value and no benefit of an increase in the coin price if it changes.
In the event that Gox spurns some individuals to want more security, if either of these State Bar's allow an attorney to hold bitcoins in trust similar to personal property by using a digital exchange I can see the following positive results. 1. The exchange would be backed by the firm's malpractice insurance, the fees to pay this insurance could be based on each transaction. (A backdoor way of insuring an unregulated currency). 2. Aside from the security of knowing the investment is secure, it also has the backing of the licensing exchanges lawyer. (No one wants to be disbarred, publicly shamed, and unemployed from stealing client funds). I'll scan in the responses I get for the conversation.

Is there any fast secure bitcoin client?

I have used Armory a bit in the past. But its slow, takes up way too much space, and is buggy. Waiting for it to download the entire blockchain take DAYS when you first install it and many hours if you haven't used it in months. Storing the entire blockchain means that my harddrive often runs out of space when using it - I had to uninstall it and move it to another external harddrive (which took more days) last time. And its a finicky piece of crap a lot of the time. It often refuses to recognize that its online. It refuses to connect to bitcoin core, or it just refuses to work in some other way.
So I've been looking for a new client. One with the following criteria:
Preferrably it would also fully explain how its security works and how to properly back up your wallet (which I know how to do, but gives extra confidence) and also preferrably allows me to choose my own transaction fee (down to 0).
Does anything like this exist? I'm pretty surprised I haven't been able to find a good secure program given how security-paranoid the bitcoin community is in general.

How secure is the message signing on the bitcoin client? How exactly does it work on the network level?

I'm actually using dogecoin, but since the technology is based on bitcoin, I figured it would be best to ask here. I understand that the client uses some sort of cryptographic function that takes address, private key, and message as inputs, but I have no idea how verification works. Wouldn't you have to compare the cyphertext to the private key at some point? What exactly is preventing the attacker from using his own client and your receiving address to forge a signature?

Tell me about how you back-up/secure your Bitcoins, and am I foolish only using a web-based client?

Hey folks, I'm still new to the BTC universe.
So I use Blockchain.info for dealing with my BTC's. I make regular backups of my wallet, but just tonight I was reading about offline cold-storage, and that if you don't use that (if you have more than a few BTC's), you're asking for trouble. So, I guess I've been really rolling the dice only relying on Blockchain and my back-ups?
And what about all of you? What is your level of expertise w/ Bitcoins, and if you have more than a few, do you store them in different wallets? Do you use a web-based service, or a self-installed client? (or both, and if so, how does that work?)
Thanks.

How secure is the Bitcoin QT client wallet encryption?

Is it perfectly safe to distribute your wallet.dat after it has been encrypted using the official bitcoin client? I keep reading about people using TrueCrypt / WinRar / you-name-it, to further secure their wallet before publicly distributing it for safekeeping. Is this necessary? If so, then why doesn't Bitcoin QT use a stronger algorithm... And if not, then why do people bother?
