TIL! this is cool

Yeah it's not totally unlike people who consider learning that they've been hacked is worth more than $x and so, even if they're not into cryptocurrencies, they leave the equivalent of $x on their computer in a "software wallet", in an obvious place.

It's not a guaranteed you'll know you've been hacked, but it's still quite a flag to leave. And there are services doing the equivalent of what you posted, but for cryptocurrencies: they contact you through email, SMS, snail mail even, if they detect that "coins at address ..." ever move.
