"Cold Storage". Maybe you've heard of it. What is it? Why is it important, and how do you do it?
In a nutshell, "Cold Storage" is a method of securely storing your Bitcoin, Bitcoin Cash, and other cryptographic assets using a device that is completely offline (not connected to the Internet). By keeping it offline, you make it essentially unhackable. Sometimes this is also called "air gapped" since there is a gap between any Internet activity and your offline machine.
This is the age of Bitcoin and the promise was that you can "be your own bank". How powerful is that?
Yet with great power, comes great responsibility. You have to learn to secure your coins!
How many times have you read on a forum that some guy's coins got stolen and he has no idea how? Or, how many people lost their coins on an exchange because they didn't know how to secure them?
My heart goes out to those people, but daggone it... I do NOT want to be that guy. And I don't want you to become a victim either.
Would you like to have the peace of mind that comes with knowing that your coins are safely locked in cold storage, completely safe from even the most clever attackers?
What if I were to tell you that with a few short lessons, I can turn you into a cold storage guru, even if you thought you sucked with computers and technology?
I will share my personal methods with you, which can be even more secure than using hardware wallets. In fact, I am attempting to give you an absolutely unhackable and unbreakable security scheme.
Not only will I give you my exact method, I will teach you all the concepts you need to have confidence and mastery in securing your coins.
If you have substantial cryptographic assets, you owe it to yourself to obtain this guide so you can prevent anyone from ever stealing your hard-earned money.
Here's an outline of what you're about to learn:

Hey Jonald!

Thanks a lot for this one,
Can you elaborate on the hardware wallets a little more?
"When you plug in a hardware wallet into your computer, you unfortunately remove the "air gap" and are now trusting the hardware device not to be compromised and not to have glitches.
Theoretically, once your hardware device (that has your private keys) is connected to your computer, anything could be signed and spent."

What do you think of Ledger's attestation? Is this technically a trusted solution because we have to trust their verification process?
What kind of mistakes would someone have to make in order to make them susceptible to having their coins stolen off of a ledger in the fashion you mention here?

Thanks again for the badass writeup!
