* My question is, how safe is it to keep screenshots of Bitcoin/crypto transactions and useful information, on ones device?
* How do I go about letting my friend know about such a habit of taking and keeping screenshots on his device that I have observed and warn him about it, without looking like I sense bad days coming?
Hmm, OP pretty good work. I really appreciate you.
OP Your friend is making a big mistake. This is a minor thing but it can cause you to lose your funds. You should explain to him and let him know that this can be a loss for you
In general, people looked at the verified transaction screenshot from an unusual point of view, wondering what would happen to this transaction, and so on. but this is based on a very disadvantage.
In this context, I tell you about the real incident of which I am a witness. Like OP's friend, this
YouTuber had taken screenshots of his assets and used them to save them on the device. He also took a screen shot of the seed phrase or password on his device. Hackers hacked Wallet by collecting all screenshots. Sometimes Gmail automatically syncs your data and the same thing happened with him, The hacker grabbed the phrase and password from the sync data and the YouTuber lost millions of dollars.
So IMH is also the same: you should not take screenshots from the device because it can cause you to lose them. The hacker is looking for such people who will have big assets so that they can be looted by making them victims of theft. So be careful Guys.
