Honestly , when I first got on to steemit, the first fear I had was what if my master key is lost, or what if something happens and how about a bank for master key.
I'm still new in this but I see how emphasized steemit has been on keeping my password safe and storing in a place that it can be accessible to me alone.
Although I don't hope to die yet, safe haven gives me reassurance that all is not lost in the case of eventuality.
I don't know any other company offering such services tho, but thank you for enlightening us on safehaven.
