It seems that you finally woke up to the harsh reality! Isolating the computer with no internet access is DEFINITELY the best way to go. The more you will read up on the subject of how easy it is to lose Bitcoin, the more you will be convinced of this.
Not only will you find yourself with an empty wallet, but you may not even realize where the hell the malware came from. Back in the day before my paranoia, I would have never guessed my wallet can be emptied from what seems to be a legitimate driver.
It does not have to be a sketchy company. Google used to praise not doing evil, now they changed their mind. All sorts of people become criminals overnight and you would have never even guessed. The point of this paranoia is having a safe Bitcoin wallet that offers no head aches. Because why stress yourself out when you can live in a peace of mind?
Things can go very south even if you are usually very careful. It is enough to do ONE mistake and it can all be gone. You may be drunk one night and not realize you are clicking on the wrong website or download link. Why stress out, I rather be peaceful instead.
Yeah, no shit, haha! I knew it sounded like the best option, but I was still considering buying a hardware wallet. However, due to some incidents I've read about in the past few years, I'm not sure if I'll feel safe enough with one, which is why I'm leaning toward buying a second laptop instead. I always thought as well that it wouldn't or couldn't happen to me, till malware was installed on my computer, which I never figured out where it came from, and luckily I only lost a couple of bucks in XRP. Losing those XRP coins was a disguised blessing, because I was also planning to move a large sum of money as well. Had I done that, I would have also lost over $3,000 in the blink of an eye.
