I just used a tool called BIP39 generator on and offline machine which you can feed entropy and it will generate a bitcoin private key. then sent funds to that address. Then just keep those details safe.
How do you handle giving access to your keys to your next of kin?

Is there an ELI5 guide to keeping coins secure when they're off-exchange? I heard terms like 'cold wallet', 'cold storage', but surely there's work that goes into creating a secure USB stick?
Use a hardware wallet to securely generate keys and sign transactions. Hardware wallet is meant for secure use of cryptocurrency, but it is not optimal for long term storage. It's important to buy devices only from trusted vendors, and to make sure they're not been tampered with (never buy them from a third party). For long term storage, you need indestructible and physically secured backup of your keys. Basically, y…
Why is that in any way more secure than writing down the private key itself? (inb4 "need to find both the hardware and the written seed words" that's equivalent to writing down the private key and then cutting the paper in half)

"There's nothing special about ZFS that requires/encourages the use of ECC RAM more so than any other filesystem."-Matthew Ahrens
His full quote, from the actual source (2003): "There's nothing special about ZFS that requires/encourages the use of ECC RAM more so than any other filesystem. If you use UFS, EXT, NTFS, btrfs, etc without ECC RAM, you are just as much at risk as if you used ZFS without ECC RAM. Actually, ZFS can mitigate this risk to some degree if you enable the unsupported ZFS_DEBUG_MODIFY flag (zfs_flags=0x10). This will checksu…
You stated "Also a good idea to use ECC Memory with the ZFS filesystem".
You should have probably stated its a good idea to use ECC memory, period. Instead you tied ECC to ZFS.

I pulled my funds from binance, writings on the wall.
Well, as large amounts of funds are pulled from Binance, we will find out if they've been stealing. A good regulatory step for the US would be to require that it can't be harder to withdraw than to deposit. Any ID requirements have to be completed before depositing , not withdrawing. And all withdrawals must be processed by T+2. Same rules as regular brokers.
I've never seen this notation before. Does it refer to blocks, hours, or (gasp!) days?

“Cryptocurrencies are only used for scammers and fraudsters.” Source?
Why is this coin 'Monero' being used by these fraudsters and criminals to hide their activity? [0] The fact that this is making ransomware run rampant and now the victim is also part of the unfortunate process of paying the ransom in Bitcoin, (and now apparently they can also pay in Monero at the hackers, 'convenience')[1] it's getting to a point where regulators need to step in before this happens to more companies…

Much easier to remember and to transcribe compared to writing down a string that looks like random garbage.

Hardware wallet is assumed to generate BIP39 seed words securely. If you don't trust the RNG, some hardware wallets also support adding your own entropy with dice rolls. [0]
