Isn't this the reason why there are bitcoin hardware wallets?

Edit: Here, I have done the precomputation for you. You want page 38, base 16 digits. https://download.wpsoftware.net/bitcoin/todl.pdf

Thanks.

Saving a copy of this.

Don't know that I'll ever use it, but I like the idea.

If the day comes that you will ever need it, you are going to wish you had printed it out ahead of time.

It's faster in wNAF and using Jacobian coordinates rather than Cartesian. Still nuts though...

Good idea, I might add some tables usable for wNAF.

And you can extend my coordinates to Jacobian by simply adding a third `1` coordinate to everything Smiley.

The dots and the plastic would be made of different materials meaning they have a different mass. This would mean the dots would make an effect on the weight (however small). But the engravings on the dice could cause it to be lighter on that face. Even throwing the die with a certain face up gives a higher chance of landing on the same face twice, especially if thrown by the same person.

Nothing is completely random.

the dots (pips) of die of that grade are usually the same material but just with a different color.

they have the exact same density.

the engraving though might be the only weak spot, and the way you throw them.

I've never gambled at a casino myself, but casino grade dice would probably have flat faces and not have engraved faces, due to this reason.
