I could relate this in the past.
Not my experience but there are a lot of people who bought Bitcoin and are not serious about holding it or trading it and when the price exploded, they are posting everywhere asking about how they would be able to get back their wallets with their private keys gone, forgotten, and deleted. Some even already threw their PCs where their bitcoin is stored.
It takes just 5-10 minutes to generate the backup file and to store it securely. This could save you from potential heartburn later. During the early days, a lot of people lost their coin holdings to carelessness. I still remember reading about an incident, in which an user lost 25,000 BTC in 2012, because he didn't bothered to enable email confirmation and 2FA to his Bitcoin wallet.
It proves to us that no matter what, we should responsibly keep on our bitcoin right now. We should neither look for the safest wallet we could not even hardware like ledger can be safely trusted. In fact attacks can be so prone to bitcoin holders that it can possibly the next topic for next weeks' hacking, just IMO. But possibly right....?
these kind of negligence can't cause trouble to the network, it caused stubborn to the holders lol.
