Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion
As to seed backups. I think the above stainless steel sheet is a great one. I am also a big fan of the stainless steel washers on a nut and bolt method, and have made several of these myself. I even designed and built a 3d printed stamping jig. I like that these are very compact and durable. There are lots of great hiding places for them etc...

I've decided against the safu ninja method or the bolt, washer and nut method even if it's very good compared to the paper alternatives, for the same reasons that Lopp already states: the pieces might separate, and even if you mark each washer with the word order number.

While there was no data loss in this test, I'm less confident in devices with tiles that could become loose and thus lost.
But it's still a very good idea.

Once it’s done, simple make a hole in your (brick) wall and cement this bad boy in. Or drill a 25mm (1 inch) hole in the top of your door and slide the storage in.
The plate can also be easily hidden or simply screwed on to your home's foundation. Or buried. I would wrap these things in plastic then bubble wrap or something similar, then in some sort of fire resistant container, then put in a wooden or metal box.
